A PROCESS FOR PREPARING ALLYL CYANIDE OF HIGH PURITY BY USING LEWIS ACID CATALYST

摘要

PURPOSE: A manufacturing method of highly pure allyl cyanide is provided to effectively remove impurities by only a simple separation refining, and to minimize side reactions. CONSTITUTION: A manufacturing method of a highly pure allyl cyanide comprises: a step of dissolving one or more Lewis acids in water selected from zinc chloride(ZnCl2), nickel chloride(NiCl2), and palladium chloride(PdCl2); a step of adding allyl chloride and adding 30-50% sodium cyanide aqueous solution; a step of controlling the pH thereof to 5-5.5 by using 10-35%; and a step of stirring the solution for 3-6 hours at 30-40 deg. C, distilling liquid crystal to separate an organic layer, and obtaining allyl cyanide. [Reference numerals] (AA) Chromatogram; (BB) Voltage(mV); (CC) Time(minutes)
