2,4-二氯苯氧乙酸合成工艺的研究进展

Research Progress on the Synthesis of 2,4-Dichlorophenoxyacetic Acid

2,4-二氯苯氧乙酸作为一种除草剂和植物生长调节剂,具有高效低毒,高选择性的优点,在农林业方面具有广泛的应用前景。本文综述了以有氯气氯化、无氯气氯化为划分依据的三种2,4-二氯苯氧乙酸合成工艺的研究进展,针对每种工艺的优缺点进行了对比分析,指出未来的研究方向应围绕着无氯气氯化合成2,4-二氯苯氧乙酸的工艺来进行深入研究。

2,4-Dichlorophenoxyacetic acid is a plant growth regulator and herbicide with high efficiency,low toxicity and high selectivity,it has broad application prospects in agriculture and forestry.The research progress of three types of 2,4-Dichlorophenoxyacetic acid based on with or without Chlorine reaction was discussed,and comparative analysis of the advantages and disadvantages of each process,it is pointed out that in the future,in the search for the synthesis process of 2,4-dichlorophenoxyacetic acid,in-depth research should be developed around the synthesis of Chlorine-free chlorination,which provides a direction for the synthesis of 2,4-dichlorophenoxyacetic acid.
