化合物描述

Dimethyl tetrachloroterephthalate (DCPA, Dacthal) is an organic compound with the formula C6Cl4(CO2CH3)2. It is a colourless solid, although commercial samples can be off white. DCPA is the dimethyl ester of tetrachloroterephthalic acid. It is used as a preemergent herbicide. It kills grass and many common weeds without killing sensitive plants such as flowers, fruits, vegetables, turf, and cotton. DCPA was first registered for use in the United States in 1958. Production of DCPA was eventually discontinued by ISK Biosciences in 1998, but the large manufacturing company AMVAC began producing the product in 2001 for use in America. Sigma-Aldrich also manufactures DCPA for use in the USA under the name Pestanal. In Australia, DCPA is the active ingredient in agchem company Farmalinx's herbicide called Dynamo 750. Currently, DCPA is only used for eggplant, kale, turnips, and sweet potatoes.

生产方法及用途

  • 生产方法

    采用强甲基化剂(如重氮甲烷或硫酸二甲酯),使四氯对苯二甲酸烷基化;或由四氯对苯二甲酰氯与甲醇酯化而得。中间体四氯对苯二甲酰氯有两种主要合成方法。
    (1)由对二甲苯侧链氯化、水解、环上氯化而得。
    (2)由对苯二甲酸经酰氯化、氯化而得。

  • 用途

    除草剂。对萌发至二叶期的稗草有显著的活性,对旱地马唐等芽前杂草也有良好的防除效果
