2-(4-Aminophenyl)-1H-benzimidazol-5-amine Chemical Properties,Uses,Production

Description

2-(4-Aminophenyl)-1H-benzimidazol-5-amine (APBIA) is a synthetic raw material for the preparation of sulfonated polyimides containing benzimidazole (SPIBIs). The synthesised SPIBIs with polyhedral oligomeric silsesquioxane glycidyl ethers (G-POSS) can be used to prepare a number of novel organic-inorganic hybrid proton exchange membranes (PEMs). The obtained membranes exhibited good crosslink density at all gel fractions above 75%. The mechanical properties, oxidative stability and hydrolytic stability of the crosslinked membranes were significantly improved compared with those of pure SPIBI membranes.

Safety Profile

Low toxicity by ingestion. Whenheated to decomposition it emits toxic vapors of NO_x.
