    • In the preparation of a phenoxy-azolyl-butanone derivative of the formula ##STR1## in which X is a halogen atom,Y is a hydrogen or halogen atom, andAz is an imidazolyl radical or a 1,2,4-triazolyl radical,wherein dichloropinacolin of the formulaCl.sub.2 CH--CO--C(CH.sub.3).sub.3is reacted with an azole of the formulaAz--Hand a phenol of the formula ##STR2## in the presence of an acid-binding agent, the improvement which comprises carrying out the reaction in the presence of a water-immiscible organic solvent at a temperature between about 40.degree. and 150.degree. C., adding to the solvent at a temperature between about 0.degree. and +80.degree. C. a mineral acid, thereby to precipitate the mineral acid salt of the phenoxy-azolyl-butanone derivative, and separating such salt. Surprisingly the product does not hydrolyze when standing in contact with the mineral acid solution. The product is a known fungicide.
    • 在制备其中X是卤素原子的式“IMAGE”的苯氧基 - 唑基 - 丁酮衍生物的制备中,Y是氢或卤素原子,并且Az是咪唑基或1,2,4-三唑基, 其中式Cl2CH-CO-C(CH3)3的二氯青霉素与酸结合剂存在下与式为Az-H的唑和式“IMAGE”的苯酚反应,其改进包括进行 在与水不混溶的有机溶剂的存在下在约40℃至150℃的温度下反应,在约0℃至+ 80℃的温度下加入无机酸,从而沉淀出 苯氧基 - 唑基 - 丁酮衍生物的无机酸盐,并分离此盐。 令人惊讶的是,当与无机酸溶液接触时,产物不会水解。 该产品是已知的杀真菌剂。
