摘 要:本文主要介绍了氟硅唑化合物的一般性质,并且指出了新农药氟硅唑开发过程,介绍了创制的一般途径;其次改进了高效、低毒、广谱有机硅杀菌剂氟硅唑合成方法,以乙醇钠代替氢化钠做俘酸剂,以格氏试剂代替有机锂试剂,合成了硅唑类氯代衍生物。在合成格氏试剂过程中,以对二氯苯代替了对溴氯苯。这些都使得生产过程的成本降低,易于工业化生产,新合成方法可用于氟硅唑化合物的合成,以便工业化的进一步发展。High -efficient, low toxicity, wide table organic silicon bactericide Fluorine silicon thiazole formate the technology to study [ The summary ] This text has introduced the general nature of the silicon thiazole chemical compound of Fluorine mainly, and has pointed out that the development course of the new agriculture chemical Fluorine silicon thiazole has introduced the general way formulated. Secondly improved high - efficient, low toxicity, wide table organic silicon bacteri cide Fluorine silicon thiazole Formate [(p-FC6H4)2Si(CH3)CH8-N-N-CH-N-CH] patent make method of drawing by report, substitute by ethanol sodium hydrogenation captures the sour pharmaceutical by sodium, The organic lithium rea- gent, take the place of the derivative after formating the type of thiazole of silicon chlorine in order to be substituted by rea- gent. In the course of formating the dose reagent, by replacing the chlorine benzene of bromine correctly to two chlorine benzene. All these make cost of the production process reduce, therefore easy industrialization production, Formate method draw lessons from at Fluorine silicon thiazole chemical compound synthetic, so that the further development of industrialization newly.
