Abstract The present invention relates to method of preparing 2-methyl-2-methyithio propionaldoxime using isobutyraldehyde as raw material. Chlorine gas is passed through the solution of butyraldehyde is organic solvent to proceed chlorination, the obtained 2-chloro-2-methyl propionaldehyde reacts with aqueous solution of sodium methyl mercaptide two form 2-methyl-2-methyl thio propionaldehyde, which further reacts with hydroxylamine to form 2-methyl-2-methylthio propionaldoxime.
