芳氧基乙酸及其酯类是一种具有多种用途的选择性除莠剂,又是植物生长调节剂。例如,2.4——二氯苯氧基乙酸(2.4—D)和2.4.5—三氯苯氧基乙酸(2.4.5——T)是选择性的除莠剂和有效的植物生长调节剂。据文献报导,氯苯氧基乙酸可用做果树催熟剂,并可增加稻谷,蔬菜的产量。又如用α-或β-萘氧基乙酸处理葫芦属类的花后,可得无核的果实。即使苯氧基乙酸也是植物生长调节剂。因此,研究探讨合成芳氧基乙酸的新技术以提高生产能力,对工农业生产有着重要的现实意义。
Aryloxyacetic acids and their esters are a selective herbicide with multiple uses and are also plant growth regulators. For example, 2,4-dichlorophenoxyacetic acid (2.4-D) and 2.4.5-trichlorophenoxyacetic acid (2.4.5-T) are selective herbicides and effective plant growth regulators. According to the literature, chlorophenoxyacetic acid can be used as a ripening agent for fruit trees, and can increase the output of rice and vegetables. Another example is the use of α- or β-naphthyloxy acetic acid treatment of flowers of the genus Cucurbita can be non-nuclear fruit. Even phenoxyacetic acid is a plant growth regulator. Therefore, it is of great practical significance to study the new technology of synthesizing aryloxyacetic acid in order to improve the production capacity.
