Catalytic synthesis of normal propyl cinnamate in acidic ionic liquid was written by Huang, Yanxian. And the article was included in Yingyong Huagong in 2012.Computed Properties of C10H20N2O4S The following contents are mentioned in the article:
Normal Pr cinnamate was synthesized with acidic ionic liquid[Hmim]HSO4 as catalyst. The effects of molar ratio of acid/alc., reaction time and the catalyst amount of ionic liquid on the yield of Pr cinnamate were investigated and the optimal conditions were as follows: amount of cinnamic acid 1.48 g (0.01 mol), the molar ratio of acid to alc. 1:6, catalyst 2 mL, reaction time 5 h. The yield of the Pr cinnamate could reach 88.2%. The ionic liquid could be reused for 5 times without much lose in activities. The structure of Pr cinnamate was characterized by IR spectrum and chromatog./mass spectrometry. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Computed Properties of C10H20N2O4S).
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. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Computed Properties of C10H20N2O4S
