Compatibility Guide

The following procedure explains how this section may be used as a guide in determining chemical compatibility information  

Determine the reactivity group of a particular product by referring to the alphabetical list in Table 12. 

For example, crotonaldehyde is listed in Table 12 as belonging in Group 19 (Aldehydes). The Chart shows that chemicals in diis group should be segregated from sulfuric and nitric acids, caustics, anunonia, and all types of amines (aliphatic, alkanol, and aromatic). According to note A, crotonaldehyde is also incompatible with nonoxidizing mineral acids. 

Notes to compatibility chart reactivity differences (deviations) within chemical groups 

Isophorone (18). and Mesityl Oxide (18) are not compatible with Group 8, Alkanolamines.

Polymers used for seat and plug seals and internal static seals include PTFE (polytetrafluoroeth ene) and other fluorocarbons, polyethylene, nylon, polyether-ether-ketone, and acetal. Fluorocarbons are often carbon or glass-filled to improve mechanical properties and heat resistance. Temperature and chemical compatibility with the process fluid are the key selec tion criteria. Polymer-lined bearings and guides are used to decrease fric tion, which lessens dead band and reduces actuator force requirements. See Sec. 28, Materials of Construction, for properties. 

Ketchup. The ketchup, tomato sauce, barbeque sauce type products are difficult to package. The compatibility factor is guided by consumer requirements and the expected shelf life or market pattern. 

A recommended USAF guide in this connection is Ref 20. Compatibility studies with spacecraft materials are reported in Refs 23, 29 32... 

Appropriate resources should be consulted for compatibility and stability information before mixing components (e.g., manufacturer s information, Trissel s Handbook on Injectable Drugs, and King Guide to Parenteral Admixtures). 

Lab experiments 98003 and 98008 indicate that the materials do not generate heat or gases when mixed nor when heated to 108 C Although the USCG chart NVC 4-75 indicates that some alcohols end amines are incompatible, ethylene diamine has been found to be compatible with many alcohols see Appendix of USCG Guide.

The demonstration that neither of the ions-at-any-price views, the main rivals of the pseudo-cationic theory, is compatible with the facts does not, of course, prove the ester theory. As I pointed out in my introduction, it is not possible to prove any scientific theory. What has been demonstrated, however, is that the ester theory will account for most of the established facts it has the advantage of being based in conventional organic chemistry, and it provides interesting guide-lines for future research and innovation. 

ASTM (E 2012-00) has developed a "Standard Guide for the Preparation of a Binary Chemical Compatibility Chart." The hypothetical example given in ASTM E 2012-00 is reproduced in Figure 4.4 specific mixing scenarios associated with this example are not described. 

An interaction matrix indicates whether the combination of two or more materials yields an undesired consequence (see ASTM E2012-99, Standard Guide for Preparation of Binary Chemical Compatibility Chart). 

The American Society for Testing and Materials (ASTM) is a not-for-profit organization that provides a forum for the development and publication of voluntary consensus standards for materials, products, systems, and services.67 One ASTM committee (E27) develops standardized physical and chemical test methods on the hazard potential of chemicals, including but not limited to reactive hazards. The committee has developed standard analytical methods for calorimetry studies in addition to a standard guide for determining binary chemical compatibility (ASTM, 2000).

Solvent-polymer compatibility problems are often encountered in industry, such as in the selection of gaskets or hoses for the transportation of solvents. A rough guide exists to aid the selection of solvents for a polymer, or to assess the extent of polymer-liquid interactions. A semi empirical approach has been developed by Hildebrand based on the principle of like dissolves like. The treatment involves relating the enthalpy of mixing to a solubility parameter, S, and its related quantity, 8, called the cohesive energy density.
