专利汇可以提供Production of m-(chlorophenoxy)toluene专利检索，专利查询，专利分析的服务。并且PURPOSE: Dichlorobenzene and an alkali metal salt or m-cresol are heated in the presence of m-cresol and copper and/or its salt to effect the reaction, thus permitting high selectivity production of the titled substance which is used as a starting substance of pyrethroid insecticides.
CONSTITUTION: (A) Dichlorobenzene and (B) an alkali metal salt of m-cresol are heated in the presence of free m-cresol and 0.01W0.45mol%, based on the compound B, preferably 0.05W0.2mol% of copper and/or its salt to effect the reaction to give the titled compound. As the copper salt, is cited cuprous oxide, cupric oxide, copper carbonate, cuprous chloride, cuprous bromide or copper sulfate. The compound A is used in an equimolar or more amount than the compound B. In order to avoid the side-reactions between the product and compound B, the amount of the compound A employed is preferably more than 1.5 times the molar quantity of the compound B or it can serve as a solvent, when the compound A is used more than 10 times the molar quantity.
