Abstract The acetalization of aldehydes has been studied with ethyleneglycol, 3‐chloro‐1,2‐propanediol, 1,2‐propanediol, and 1,2,3‐propanetriol using resin‐D72 catalyst in high yields under reflux and water separator conditions. The reaction is simple, efficient, and chemoselective and does not involve any other additive.
Bio-based glycerol and aldehydes have been valorised by acetalization reaction over novel macroporous sulfonated polystyrene-type resins (MR-SP20-SO3H and MR-SP50-SO3H). The influence of reactants molar ratio, catalyst amount, temperature, and reaction time on the activity and selectivity to acetals have been investigated. Results showed that MR-SP20-SO3H and MR-SP50-SO3H confirm a high performance
生物基甘油和醛已通过缩醛化反应在新型大孔磺化聚苯乙烯型树脂(MR-SP20-SO 3 H 和 MR-SP50-SO 3 H)上获得价值。研究了反应物摩尔比、催化剂用量、温度和反应时间对缩醛活性和选择性的影响。结果表明,MR-SP20-SO 3 H 和 MR-SP50-SO 3 H 证实了在甘油衍生物 1,2-丙二醇、1,3-丙二醇、3-甲氧基-1,2-丙二醇的缩醛化中的高性能和单醋精;这些催化系统可实现回收和再利用。
