| 摘 要： | 利用异丁醇胺对异海松酸的选择性结晶特性,采用湿地松松脂蒸馏后得到的新鲜松香,或者采用工厂生产得到的湿地松松香进行热异构使大部分枞酸型树脂酸异构成为枞酸,而后将异海松酸与异丁醇胺反应形成异海松酸的异丁醇铵盐而与其他树脂酸进行分离,再利用复式重结晶法纯化异海松酸铵盐结晶,分解游离得到异海松酸,其得率达到原料松香质量分数的10.1%,纯度达到95.4%,提取率为42.2%.

| Abstract: | Taking advantage of the selectively crystalline specialty of 2-amino-2-methyl-1-propanol toward isopimaric acid,butanolidine isopimarate(2-amino-2-methyl-1-propanol isopimaric acid salt) was prepared by reacting 2-amino-2-methyl-1-propanol with thermally isomerized slash pine rosin that was freshly prepared from oleoresin or rosin,then purified by multi-recrystallization.Thereafter,isopimaric acid was isolated from the butanolidine isopimarate by acidic decomposition in a yield of 10.1 % based on the rosin,with purity of 95.4 % isopimaric acid.The isolation yield of isopimaric acid is 42.2 % based on its content in rosin. |
