在蔗糖业中开展生物炼制,利用生物质开发绿色平台小分子(如乙酰丙酸),是解决能源危机的重要途径,也符合蔗糖业规避风险和提高市场应变能力的要求。文章分析了蔗糖制备乙酰丙酸的原理和催化剂选择,并以几种固体无机酸催化为例说明,制备中可采用超声-微波协同技术提高生产效率,高效液相色谱法在分离提纯产品中能发挥较好作用。 In the sugar industry to carry out biological refining, the use of biomass development green platform small molecules (such as levulinic acid) is an important way to solve the energy crisis, but also in line with sugar cane industry to avoid risks and improve market resilience requirements. In this paper, the principle and catalyst selection of levulinic acid prepared by sucrose were analyzed. The catalysis of several solid inorganic acids was taken as an example to illustrate that ultrasonic-microwave synergism can be used to improve the production efficiency. High performance liquid chromatography Play a better role.
