Diphenamid Specification

N,N-Dimethyl-2,2-Diphenylacetamide (CAS NO.957-51-7) is a colorless to off-white crystals. It is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P₂O₅ or SOCl₂ generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). Also it is decomposed by strong base or acid.
