摘　　要：在超低酸催化体系中,转化生物质基糠醇生成乙酰丙酸正丁酯。通过响应面法研究了反应温度、反应时间和催化剂用量以及它们之间的交互作用对乙酰丙酸正丁酯得率的影响,优化了糠醇生成乙酰丙酸正丁酯的反应条件。结果表明:反应温度为150℃,反应时间为3.0 h,催化剂硫酸浓度为0.0086 mol/L的最佳反应条件下,乙酰丙酸正丁酯得率为73.32%。N-butyl levulinate is produced from biomass-derived furfuryl alcohol by using the extremely low acid as catalyst system. The effects of reaction temperature, reaction time, amount of catalyst and their interaction on the yield of n-butyl levulinic acid are studied by response surface method. The reaction conditions for the formation of n-butyl levulinic acid from furfuryl alcohol are optimized. The optimum processing conditions are as follows: the reaction temperature is 150 ℃, the reaction time is 3.0 h, the concentration of sulfuric acid is 0.008 6 mol/L. Under the optimum conditions, the yield of n-butyl levulinate is 73.32%.
