The best reference books on manufacturers of chemical engineering equipment and products are the Chemical Engineering Catalog and the Chemical Materials Catalog. These catalogs are published annu-Rly. The Chemical Materials Catalog is a compilation of chemical... 

Hemoglobin Use Hemoglobin Substrate Powder (Sigma Chemical Co., Catalog No. H2625) or a similar high-grade material that is completely soluble in water. 

Pressure-relief Devices. Spring-loaded pressure-relief valves and rupture disks of thin sheet material are available from manufacturers (see " Chemical Engineering Catalog ). When using pressure-relief disks, a strictly noncorrosive material must be specified because of the requirement of maintaining strength in very small thickness. 

The catalog features searches by chemical name, catalog number, or keyword for over 2400 chemicals. It al.so includes Material Safety Date Sheets (MSDSs). 

To seat ch for available starting materials, similarity searches, substructure searches, and some classical retrieval methods such as full structure searches, name searches, empirical formula searches, etc., have been integrated into the system. All searches can be applied to a number of catalogs of available fine chemicals (c.g, Fluka 154]. In addition, compound libraries such as in-housc catalogs can easily be integrated. 

Because of the number of chemicals and subsequent multiple number of potential reactions, it is impractical and (perhaps impossible) to list all potential reactions. Several systems exist for determining the reactions between classes of chemicals, however, none of them is definitive. Because all of the potential reactions for individual chemicals are not cataloged and because there are no (or very few), pure solutions of waste materials, laboratory compatibility testing is recommended for most materials. An appropriate protocol for compatibility testing would involve the following steps ... 

Of these sources, Kirk-Othmer s Encyclopedia of Chemical Technology is particularly recommended for questions on chemistry and on end uses. For information on properties and on toxicity and handling hazards, Patty s Industrial Hygiene, Material Safety Data Sheets (MSDS), and the Aldrich catalog are very nseful. Questions on industrial chemistry should be directed to Ullman s Encyclopedia of Industrial Chemistry, and the texts by Chenier, Heaton, and White. Hawley s Condensed Chemical Dictionary is valuable as a source for dehnitions of the terms (language) of chemistry. 

The sources of these standards include FM manufacturers, synthesis by researchers (especially in the case of NM metabolites), and specialty chemical catalogs. When possible, it is preferable to obtain these standards directly from the FM manufacturers in order to use the authentic material being discharged to wastewater treatment. In all cases, the purchased, synthesized, or obtained standards must be extensively analyzed to confirm the chemical structure and purity.
