【Abstract】 A linear polymer catalyst polyvinyl chloride bound N alkyl N methyl aminopyridine was synthesized by polyvinyl chloride resins reacting with N methylaminopyridine in THF and NaH. Compared to other polymer bound dimethylamino pyridine, the new synthesized catalyst can be dissovled in organic reaction solution, therefore acetylation of alcohols is homogeneous reaction, after the reaction was finished, the catalyst can be isolated from organic reaction solution by adding water and reused. The active of the catalyst was studied by acetylation of linalool. A reaction condition is: linalool 0.1 mol, acetic anhydride 0.15 mol. catalyst 2 g, reaction time 20 h, reaction temperature 55~60 ℃, transforming ratio of linalool is above 99%, linalyl acetate is about 57%.更多还原
