Brzeczek-Szafran, Alina; Wieclawik, Justyna; Barteczko, Natalia; Szelwicka, Anna; Byrne, Emily; Kolanowska, Anna; Swadzba Kwasny, Malgorzata; Chrobok, Anna published an article in 2021, the title of the article was Protic ionic liquids from di- or triamines: even cheaper Bronsted acidic catalysts.Synthetic Route of 5036-48-6 And the article contains the following content:

Dicationic and tricationic ionic liquids, synthesized by proton transfer from sulfuric acid and corresponding di- and triamines, were characterised and used as Bronsted acidic catalysts in biodiesel production It has been demonstrated that the new ionic liquids are less expensive than those based on monoamines (even on triethylamine) and are highly acidic. Their performance in a model catalytic esterification reaction surpassed that of sulfuric acid and other literature reports, due to the capability of the ionic liquids to absorb water while phase-separating the ester, thereby shifting the reaction equilibrium towards products. The overall catalytic performance was an interplay between acidity (quantified by Gutmann AN) and phys. properties: d. and viscosity, which enabled easy phase separation, thereby separating water from the ester. The substrate scope and recycling studies have demonstrated that the new ionic liquids are robust and recyclable catalysts. The experimental process involved the reaction of N-(3-Aminopropyl)-imidazole(cas: 5036-48-6).Synthetic Route of 5036-48-6
