Efficient Combination of Recyclable Task Specific Ionic Liquid and Microwave Dielectric Heating for the Synthesis of Lipophilic Esters was written by Arfan, Atef;Bazureau, Jean Pierre. And the article was included in Organic Process Research & Development in 2005.SDS of cas: 478935-29-4 The following contents are mentioned in the article:
Mild and efficient esterification reactions of carboxylic acids with neo-pentanol were carried out using task-specific ionic liquids with hydrogen sulfate counter-anion under microwave irradiation The latent acidity of the ionic liquid was introduced by anion metathesis from hydrogen sulfate with the corresponding imidazolium or pyridinium halides. The catalyst [C4mim][HSO4] modified with 5% of concentrated sulfuric acid was reused three times without considerable loss of activity in esterification using classical heating in oil bath. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4SDS of cas: 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.SDS of cas: 478935-29-4
