| | 2-(4-Aminophenyl)-1H-benzimidazol-5-amine Usage And Synthesis |
| 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] |
