NOTICE This book is intended to provide data about chemical incompatibilities and other hazards. It is not intended as a primary source of research information. It cannot be assumed that all necessary warnings and precautionary measures are contained in this work, and that other, or additional, information or assessments may not be required. Extreme care has been taken in the preparation of this work and, to the best knowledge of the publisher and the editors, the information presented is accurate. No warranty, express or implied, is made. Information may not be available for some chemicals; consequently, an absence of data does not necessarily mean that a substance is not hazardous. Neither the publisher nor the editors assume any liability or responsibility for completeness or accuracy of the information presented or any damages of any kind alleged to result in connection with, or arising from, the use of this book. The publisher and the editors strongly encourage all readers, and users of chemicals, to follow the manufacturers' or suppliers' current instructions, technical bulletins, and material safety data sheets (MSDSs) for specific use, handling, and storage of all chemical materials. The chemical profiles presented in this guide book are representative of known and potential incompatible materials and neither purports to be complete, nor is it intended as a primary source of research information. In fact, although there are other fine works that report on chemical accidents, it is nearly impossible to cover all of the potential combinations resulting from the 3,000 high-production volume chemicals used in the United States and elsewhere, let alone the hundreds of thousands of chemicals registered with the Chemical Abstract Service of the American Chemical Society (ACS).
ACKNOWLEDGMENT Thanks are due to those individuals who reviewed and constructively commented on publication of the first edition and during the development of this second edition. We also want to thank the many scientists, contract employees, and other individuals who developed the various documents and databases that provided so much of the data that were compiled for this book. Thanks are also due to Bob Esposito of John Wiley & Sons for his encouragement and suggestions for this edition.
INTRODUCTION More than five years ago, Rapid Guide to Chemical Incompatibilities was published. This second edition has outgrown Wiley's smaller "Rapid Guide" series and has been enlarged and renamed Guide to Chemical Incompatibilities. Designed to fill the need for a portable and easy-to-use reference on reactive substances commonly found in commerce, the objective of this book is to aid those having all levels of knowledge and especially those who may not be chemists by profession, but who are trusted with the protection of human health and the environment. More specifically, this is a guide for personnel in the fields of safety, first-response, and transportation, as well as workers, supervisors, and plant management responsible for the handling, storage, and conveyance of chemical materials. To this end, the summary information covers flammability, violent and explosive binary reactions, incompatibilities, and reactions that may result from physical change. This edition contains nearly 9,500 chemical incompatibility profiles using more than 12,000 chemical and trade names. Nearly all the chemical profiles from the first edition have been revised, expanded, and rewritten. To save space, many similar and contiguous chemical synonyms (with the same CAS number) have been combined into a single entry. At the suggestion of reviewers of the first edition, Spanish language names and many additional flash points have been added and generally rounded down (i.e., 98.5 is rounded down to 98.0). More information has been added on the effects of chemicals that come into contact with construction materials, rubbers, plastics, and coatings. To help users with general chemical terms, a glossary has been included. Temperatures appear in both Fahrenheit and Celsius using the format (xxx°F/xxx°C). A more detailed description of profile contents appears in the next section. All CAS numbers have been checked. It is hoped that this new edition will save the reader time by providing information that would otherwise be difficult to obtain from multiple other sources. Any comments, suggestions, or advice from users are both welcomed and appreciated. All correspondence should be submitted in writing to the publisher.
HOW TO USE THIS BOOK The term incompatibility is used to describe a wide range of chemical reactions that might include self-ignition from contact with air, the generation of heat resulting from contact of a chemical with moisture; decomposition; the generation of toxic gases; the heating, overflow, and rupture of containers; polymerization; the formation of new and possibly more dangerous compounds; fire, detonation, and explosion; or any combination of these or other actions. Using chemical names and Chemical Abstracts Service (CAS) numbers, readers can locate concise incompatibility profiles for thousands of commercial chemicals that may be found in the industrial workplace, frequently stored, and transported in bulk. Chemical names, regulatory names, alternate names, commonly used "trivial" names, and in many cases, product and trade names can be looked up directly without the reader's having first to consult interim indices or charts. To avoid confusion with like-sounding names or multiple names with exact spellings, CAS registry numbers (in the format xxx-xx-x) have been provided. These numbers are assigned to all chemicals registered with the Chemical Abstracts Service of the American Chemical Society, and should always be used in conjunction with a substance name for positive identification. A substance's incompatibility profile is based on the following information (as available): Incompatibility or reactions with common materials or conditions, including air and moisture. Incompatibility or binary reactions with another chemical substances. Incompatibility or reactions with structural materials such as metals, glass, concrete, etc. Incompatibility or reactions with protective materials such as plastics, rubber, and coatings. Information, as known, related to the ability of chemical substances to accumulate dangerous static electrical charges. The ability, when known, of a chemical (e.g., ethers) to form unstable and potentially explosive peroxides, or to cause polymerization. When polymerization inhibitors are known or recommended, they have been included. According to National Safety Council Data Sheet 1-655/rev. 1982, peroxides can be rendered harmless with iron(II) sulfate (1:1) or by passing the liquid material over a bed of activated aluminum oxide [a-alumina (OSHA)]. When a chemical mixes with air to form an explosive mixture, the flash point has been provided in both degrees Fahrenheit and Celsius. Flash point is defined as "the minimum temperature (@ 760 mm Hg/1 atm.) at which the liquid gives off sufficient vapor to form an ignitable mixture with air near the surface of the liquid or within the test vessel used. Data are apparatus- and procedure-dependent." However, in practice (e.g., outside the laboratory), ignition may occur at lower temperatures than those provided; it should also be noted that flash points found in the literature may differ for various reasons, including the presence of impurities. When a precise flash point is required, it should be established or verified by testing a technical-grade sample of the chemical substance. It should be noted that the U.S. OSHA and U.S. DOT have differing definitions for the terms "flammable" and "combustible." DOT defines a flammable liquid as one that, under specified procedures, has a flash point of not more than 141°F/60.5°C. A combustible liquid is defined as one having a flash point above 141°F/60.5°C and below 200°F/93°C. This definition is used in this book. Many experts use 100°F/37.8°C as the point to differentiate these
terms. Therefore, for reference only, the following listing from 29 CFR 1910.106 is used by OSHA to classify flammable or combustible liquids: Class IA flammable liquid: Flash point below 730F and boiling point below 1000F Class IB flammable liquid: Flash point below 73°F and boiling point at or above 1000F Class IC flammable liquid: Flash point at or above 73°F and below 1000F Class II combustible liquid: Flash point at or above 1000F and below 1400F Class IHA combustible liquid: Flash point at or above 1400F and below 2000F Class HIB combustible liquid: Flash point at or above 2000F Extremely flammable liquids should be transported by gravity, pumping, or inert gas propellent. The use of compressed air will cause the spreading of fumes and air-vapor mixtures. In confined spaces combustion can lead to violent explosion. Some materials are sensitive to heat and can deflagrate without any addition of air. When heated to decomposition, many substances emit toxic, flammable, and explosive vapors; some will ignite or explode. Although intended to be helpful in preventing, or at least minimizing, the harmful effects of chemical accidents, this guide will not address all possible contingencies that may be associated with storage or chemical mixtures, and should not be considered a substitute for the user's own knowledge or judgment. In compiling this manual the editors used various sources of information; occasionally, contradictory data were found in the literature. Consequently, the editors and the publisher strongly urge users to consult chemical manufacturers' and suppliers' technical bulletins, material safety data sheets, labels, and shipping and other documents related to protection from, and the safe handling and storage of, all chemical substances. Furthermore, users are cautioned that the absence of specific reaction information in no way implies that different materials, or combinations of materials, under any set of conditions, may be safely mixed or otherwise used. In like manner, users must weigh comments about the "violence" of particular reactions, which may be affected by factors such as the amount of material, physical properties, temperature, use of closed or restricted systems, and so on. In some cases, very small quantities of contamination, or the presence of other materials in the working environment, may act as a catalyst and produce violent reactions such as polymerization, disassociation, and condensation. It should be noted that foreign names do not contain distinctive or diacritical marks used to aid in a particular country's pronunciation; therefore, a name such as ACIDO FOSFORICO (phosphoric acid) or ACIDO NITRICO (nitric acid) are the same in both Italian and Spanish. The term "incompatible" generally means that there may be a reaction (possibly violent) with another material which may be other than binary. The reaction with another material may occur when subjected to "outside forces" such as warming, change in vapor pressure, or other physical change.

Common transition metals include cobalt, iron, manganese, nickel, vanadium. vapor pressure: When a substance evaporates, its vapors create a pressure in the surrounding atmosphere; therefore, vapor pressure is a measurement of how readily a liquid or solid mixes with air at its surface. This measurement is expressed in millimeters of mercury (mm of Hg), at 68°F/20°C and normal atmospheric pressure (760 mm Hg). A vapor pressure above 760 mm indicates a substance in the gaseous state. The higher a product's vapor pressure, the more it tends to evaporate, resulting in a higher concentration of the substance in air and therefore increased likelihood of breathing it in. volatiles: A substance, usually a liquid, that easily vaporizes or evaporates to form a gas or vapor. Ziegler catalyst: Organometallic compounds generally made up of an alkyl metal (from Groups I, II, or II of the Periodic Table) plus a halide of a transition metal (from Groups IV to VIII) and used in the Zeigler process for making synthetic rubbers and high-density polymers.
