Synthesis of n-Butyl Furoate Catalyzed by (3-Sulfopropyl) Triphenyl-Phosphine Phosphotungstate
摘要
Abstract
3-Sulfopropyl)triphenyl-phosphine phosphotungstate catalyst ([TPSPP]3PW12O40) was synthesized from triphenylphosphine, 1,3-propane sultone and phosphotungstic acid through two step reactions and characterized by means of ESI-MS, NMR and FTIK. Its catalytic performance in esterification of furoic acid with ra-butanol to n-butyl furoate was evaluated. Several heteropoly compounds with Keggin-structure were prepared and supported on porous silica by impregnation. Their catalytic performances in the esterification were compared with [TPSPP]3PW12O40 catalyst. The effects of catalyst dosage, mole ratio between the reactants, oil bath temperature and reaction time on the n-butyl furoate yield were investigated. Under the optimal reaction conditions; furoic acid 20 mmol, n( [TPSPP]3PWl2O40) : n(n-butanol) : n(furoic acid) 0.005 =5.4 : 1, oil bath temperature 150 ℃ and reaction time 3 h, the n-butyl furoate yield could reach 96.9% and the catalyst could be recycled four times.关键词
