Oxime ether synthesis method

The invention discloses an oxime ether synthesis method. The method comprises the steps as follows: putting ketoxime and organic base in the molar ratio being 1:(1-1.5) into a high-pressure reactor, adding an organic solvent, controlling the reaction temperature at 10-60 DEG C, introducing an alkylation reagent, conducting a reaction for 2-6 h, filtering a reaction solution after the reaction ends, after removing the solvent from filtrate, performing distillation or crystallization to obtain an oxime ether product; the chemical structural formula of oxime ether is shown in formula (I), whereinR1 and R2 independently represent C1-C3 alkyl; R is substituted benzyl or C1-C3 alkyl. An organic phase one-pot method process is adopted to replace a water phase stepped method process, oxime etherhydrolysis side reactions are avoided, the process operation is simplified, the reaction yield is increased, and discharge of wastewater is reduced.
