摘要
甘油作为一种重要的生物质基平台化合物,可以和羰基化合物在酸性催化剂的作用下发生缩合反应生成缩醛和缩酮,缩醛和缩酮可广泛应用于燃料添加剂、香料、兽药制剂、塑化剂和多元醇等领域。从甘油缩醛和缩酮的合成机理出发,简单比较了传统的液体酸催化剂与固体催化剂的催化性能,重点介绍了丙酮甘油缩酮、环己酮甘油缩酮、苯甲醛甘油缩醛、甘油甲醛缩醛和甘油乙酰丙酸酯缩酮等几种重要甘油缩醛和缩酮的合成工艺,并概述了其生产技术,最后展望了生物质基甘油缩醛和缩酮的开发应用前景。
As an important biomass-based platform compound,glycerol can be condensed with carbonyl compounds under the action of acidic catalysts to form acetals and ketals.Acetals and ketals are widely used in the fields of fuel additives,perfumes,veterinary medicine preparations,plasticizers and polyols.The catalytic performance of traditional liquid acid catalyst and solid catalyst was compared based on the synthesis mechanism of glyceryl acetal and ketal;then,the synthesis processes of several important glycerol acetals and ketals such as solketal,cyclohexanone glycerol ketal,benzaldehyde glycerol acetal,glycerol formal and glycerol levulinate ketal were introduced,and their production technology was summarized;finally,the development and application prospects of bio-based glycerol acetal and ketal are prospected.
