摘要

以大孔聚苯乙烯氯球为原料

在氮气保护及氢化钠存在下

将其与４-氨基吡啶及硫酸二甲酯反应

制成聚苯乙烯支载Ｎ-苄基-Ｎ-甲基氨基吡啶（ＢＭＡＰ）催化剂．与文献相比

该法具有反应时间短

价格低

制备的ＢＭＡＰ活性高等特点．经过元素分析、ＦＴＩＲ及ＭＡＳ１Ｈ-ＮＭＲ对其结构进行表征．利用该催化剂进行了芳樟醇的乙酰化反应

对影响反应的诸因素如反应物料比

反应时间

反应温度等进行了讨论

芳樟醇的转化率为９９％以上

总酯率为９５％左右

其中芳樟酯的产率为６０％以上（目前工业上使用Ｈ３ＰＯ４催化剂芳樟酯产率为５０％左右）．催化剂通过再生连续使用五次

活性无明显下降．

Abstract

Polystyrene supported N benzyl N methyl aminopyridine(BMAP) was prepared through chloromethylated polystyrene beads (made in the chemical plant of Nankai University in Tianjin

Cl%:6.49

DVB:2%) treated with 4 aminopyridine and dimethyl sulphate. All the reaction were performed under efficient stirring and protection of N 2. BMAP was determined by elementary analysis

FTIR and MAS 1H-NMR. BMAP is a useful catalyst for acetylation of linalool. Some experimental paramaters (anhydride and alcohol molar ratio

reaction temperature

reaction time

etc) were discussed.The conversion of linalool is over99%

toal esters is about 95% and Linalyl acetate is above 60%.There are advantage in comparison with literature:reaction time shorter

price lower and the synthesized BMAP more active.
