摘要: 以杂多酸磷钼酸为催化剂合成了马来海松酸。考察了催化剂用量、溶剂、反应时间及原料配比等对双烯加成反应的影响。实验结果表明,松香与马来酸酐摩尔比为1.7:1,催化剂质量分数为2.0%,甲苯作溶剂,反应时间4h,反应得率可达78.9%。

Abstract: Maleopimaric acid can be synthesized by Diels-Alder reaction from rosin and maleic anhydride catalyzed by phosphato-molybdic acid. The effects of reaction parameters, such as catalytic amounts, temperature, times and rosin/maleic anhydride molar ratio, were investigated. Based on the experimental results, it is found that with mass part of catalyst 2.0%, toluene as solvent, reaction time 4 h and rosin/maleic anhydride molar ratio 1.7:1 the yield of 78.9% can be obtained.

Key words: phosphato-molybdic acid, maleopimaric acid, gum rosin
