研究了固体碱催化剂上生物质来源的糖直接液相转化为乳酸甲酯的反应。在最佳反应条件下，乳酸甲酯的收率可达29.45%。考察了反应时间、反应温度和催化剂焙烧温度对反应的影响。采用XRD、CO2-TPD和N2-吸附技术对新鲜和使用过的催化剂进行表征。发现具有最高浓度弱碱性位点的MgO对糖转化为乳酸甲酯表现出最高的催化活性。(C)2011 Elsevier B. V.保留所有权利。
A study of the liquid-phase conversion of biomass-derived sugars directly to methyl lactate catalyzed over solid base catalysts is presented. The yield of methyl lactate reached 29.45% under optimal reaction conditions. The effects of reaction time, reaction temperature, and catalysts calcination temperature were investigated. Fresh and used catalysts were characterized by XRD, CO2-TPD, and N-2-adsorption techniques. MgO with the highest concentration of weakly basic sites was found to show the highest catalytic activity for the conversion of sugars to methyl lactate. (C) 2011 Elsevier B.V. All rights reserved.
