    Abstract: A process for preparing oxime ethers of the formula I,in which the substituents R and R can be identical or different and can each be cyano, alkyl, haloalkyl, cycloalkyl, phenyl and naphthyl, and R can be alkyl, by alkylation of oximes of the formula IIunder basic conditions with an alkylating agent from the group of alkyl halides, dialkyl sulfates and dialkyl carbonates, wherein the reaction is carried out in a mixture consisting of5 to 25% by weight of polar aprotic solvents selected from the group of nitrites, N-alkylpyrrolidones, cyclic urea derivatives, dimethylformamide and dimethylacetamide,55 to 95% by weight of nonpolar solvents selected from the group of aliphatic hydrocarbons, aromatic hydrocarbons, alkyl alkylcarboxylates and ethers, and0 to 25% by weight of water, the contents thereof totaling 100%.
