综述了合成肉桂酸的催化研究进展,介绍了各种不同催化剂下合成肉桂酸的工艺条件和结果。认为在现有肉桂酸合成技术中,负载型催化剂催化合成效果最佳,产率可达90%以上,且活性高、反应时间短,无污染,比其它方法有显著的优越性。 The progress of the research on the synthesis of cinnamic acid was reviewed. The technological conditions and the results of the synthesis of cinnamic acid under various catalysts were introduced. It is considered that in the existing cinnamic acid synthesis technology, the supported catalyst has the best performance in catalytic synthesis with a yield of over 90%, high activity, short reaction time and no pollution, and has obvious advantages over other methods.
