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。
