| Specification: |
4,4'-Methylenedianiline dihydrochloride (CAS NO.13552-44-8) is also called 4,4'-Methylenedianilinium dichloride ; Methylenedianiline dihydrochloride ; 4,4'-Methylenebisaniline bishydrochloric acid ; 4,4'-methylenebisbenzenamine dihydrochloride ; 4,4'-Methylenedianiline Dihydrochloride Salt . 4,4'-Methylenedianiline dihydrochloride (CAS NO.13552-44-8) may be sensitive to prolonged exposure to air and light. 4,4'-Methylenedianiline dihydrochloride (CAS NO.13552-44-8) behaves as an acid in aqueous solution . Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. Flash point data for 4,4'-Methylenedianiline dihydrochloride (CAS NO.13552-44-8) are not available; however, 4,4'-Methylenedianiline dihydrochloride (CAS NO.13552-44-8) is probably combustible. |
