Esterification reactions of acetic acid, methoxyacetic acid and methylmalonic acid with neo-pentanol, hexanol, heptanol and decanol have been investigated in three ionic liquids with hydrogen sulfate, dihydrogen phosphate as counteranions and also two ionic liquids modified with HPF6 as catalyst. The nature of both the counteranion and cation influence the behavior of the catalyst. Good yields and high selectivities were obtained and all the produced esters could be easily recovered due to their immiscibility with the ionic liquid as green reaction medium. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Product Details of 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Product Details of 478935-29-4
