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

Uses

2-(4-Aminophenyl)-1H-benzimidazol-5-amine is a useful as an aerogel lithium battery separator.

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.

Uses

2-(4-Aminophenyl)-1H-benzimidazol-5-amine is a useful as an aerogel lithium battery separator.

Synthesis Reference(s)

[1] Process for preparing 2-(4-aminophenyl)-5-amino-benzimidazole and substituted derivatives. US4417056A

Safety Profile

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

Synthesis

In a process for the preparation of 2-(4-Aminophenyl)-1H-benzimidazol-5-amine and substituted derivatives thereof by cycloreduction of starting material N-(4-nitrobenzoyl)2,4-dinitroaniline or a substituted derivative thereof by means of hydrogen gas in the presence of a catalyst based on a metal belonging to Group VIII of the Periodic Classification of the elements.[1]
