蔗糖脱水制备5-羟甲基糠醛的研究
Preparation of 5-Hydroxymethylfurfural by Dehydration of Sucrose
摘要
Abstract
The preparation of 5-hydroxymethylfurfural ( HMF ) from sucrose was studied in the presence of Br nsted-Lewis composite catalytic system. The effects of reaction conditions on the yield of 5-hydroxymethylfurfural were examined. The optimal reaction conditions were obtained as follows: sucrose 2. 0 g, composite catalytic system HCl-CrCl3(mass ratio 5:1) 0. 8 g , dimethyl sulfoxide 20 mL, reaction time 30 min and reaction temperature 200 ℃. Under the above conditions, the conversion of sucrose was 100 %, and the yield of 5-hydroxymethylfurfural reached 72. 7 %. Moreover, CrCl3 had a good stability on the product 5-hydroxymethylfurfural. It could avoid 5-hydroxymethylfurfural over-reacting to form formic acid and levulinic acid by the hydration/decarboxylation reaction to a certain extent.关键词
