Pd/BC was used as catalyst for disproportionation of slash pine rosin.

研究钯/竹炭(Pb/BC)催化剂对湿地松松香的歧化反应,确定了最佳反应条件,催化剂用量为原料松香质量的0。

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.

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。

In this study, the preparation of Pd/BC catalyst and its application in slash pine rosin was first investigated systemically with the bamboo charcoal as the support.
