Research on High Efficiency Method of Preparing Unsaturated Alcohols from Unsaturated Chlorohydrocarbons

Based on the catalytic hydrolysis method,a high efficiency method of preparing unsaturated alcohols from unsaturated chlorohydrocarbons was developed. The key factors that influenced the process of preparing unsaturated alcohols were investigated,which included catalyst type and usage,cocatalyst type,chlorohydrocarbon type,reaction time and temperature. Under the optimized conditions,the hydrolysis efficiency of unsaturated chlorohydrocarbon was more than 80%. To keep the hydrolysis efficiency,every recycle of the hydrolysis solution,0. 5% mol catalyst was added to the solution. All the unsaturated alcohols prepared have been characterized by GC and1 H NMR.
