    摘要： A process for obtaining pure 2-substituted-3(2H)-isothiazolones is presented, wherein the substituent is alkyl, linear or branched. By developing suitable conditions, the isothiazolone hydrochloride is isolated from the complex reaction media wherein it is formed as readily filterable crystals of high purity. Such purified crystals are then utilized in isolation of isothiazolone of high purity.
