ZnCl_2 催化下的β-蒎烯与多聚甲醛的反应条件优化研究

STUDY ON OPTIMUM CONDITION OF REACTION BETWEEN β-PINENE AND PARAFORMALDEHYDE CATALYZED BY ZnCl_2

以松节油中的 β 蒎烯为起始原料 ,在无水ZnCl2 催化下 ,和多聚甲醛反应 ,合成了诺卜醇。采用均匀设计的方案 ,研究了反应物料配比、反应时间、反应温度对诺卜醇产率的影响。按均匀设计优化条件安排实验 ,实际得率为 71 31% ,在预测范围内 。

Nopol was synthesized from β pinene in turpentine and paraformaldehyde catalysed by ZnCl 2. Uniform design was adopted to study reactant proportion, reaction time, reaction temperatrue which influence the yield of nopol. The experiment was arranged according to the optimum conditions from uniform design to obtain the actual yield at 71.31%, which is within the expected range and is superior to all other experiments.
