重要化工原料——异丁醛的制备方法

Abstract

论述了异丁醛的制备方法，其中负载型水溶性膦铑催化剂（SAP）促进下的丙烯氢甲酰化反应是异丁醛的主要制备方法。通过反应条件的调节，配位基团及载体的选取，可有效地控制主副产物的比例；由甲醇与乙醇或甲醇与正丙醇在负载型V2O5催化剂促进下的反应是制取IbA的又一途径，V2O5负载量及载体种类均对IbA的产率有着明显影响

Methods For manuFacturing isobutyraldehyde (IBA) are reviewed, with the main one being hydroformylation of propylene promoted by the supported aqueous-phase(SAP) Rh catalyst.The ratio of the main product to the byproducts can be controlled by regulation of reaction conditions and selection of ligands and supports.Another noval method For synthesizing IBA From methanol and ethanol or 1-propanol is developed using V 2O 5/TiO 2-MO catalyst,in which the supported V 2O 5 content and the sort of support obviously inFluence the yield of IBA.
