以H_3PW_6Mo_6O_(40)/TiO_2-WO_3为催化剂,苯甲醛和1,2-丙二醇为原料合成了苯甲醛1,2-丙二醇缩醛,用正交实验法研究了物料配比、催化剂用量、带水剂用量、反应时间等因素对收率的影响。结果表明,在n(苯甲醛):n(1,2-丙二醇)=1:1.3,催化剂用量为反应物料总质量的1.2%,带水剂环己烷6mL,反应时间75min的优化条件下,苯甲醛1.2-丙二醇缩醛的收率可达79.1%。 The benzaldehyde 1,2-propanediol acetal was synthesized from H_3PW_6Mo_6O_ (40) / TiO_2-WO_3 catalyst by using benzaldehyde and 1,2-propanediol as raw materials. The effects of material ratio, amount of catalyst, Dose, reaction time and other factors on the yield. The results showed that under the optimized conditions of n (benzaldehyde): n (1,2-propanediol) = 1: 1.3, the amount of catalyst was 1.2% of the total mass of the reaction mass, 6 mL of cyclohexane cyclohexanone and the reaction time was 75 min, Benzaldehyde 1.2-propanediol acetal yield of up to 79.1%.
