摘要:以自制A胺为有机胺原料,采用胺盐法,以95%乙醇为胺盐的重结晶溶剂,从松香酸中分离提纯得到纯度90.91%的枞酸,该方法所用原料A胺价廉,重结晶溶剂用量小,毒性小,不仅大幅度降低了成本,还具有环保作用。样品用1H NMR、UV、IR和GC-MS鉴定了结构。研究了异丙胺、环己胺、十八烷基伯胺、二丁胺、三乙胺和A胺等多种有机胺盐法提纯枞酸,分析了有机胺的碳原子数和伯仲叔胺对提纯的影响,得到的90%纯度的枞酸在5 kPa、-15℃条件下储存2个月纯度基本不变。
Abietic acid of 90.91% purity was obtained by amine salt method, using self-prepared amine A as raw material and 95 % ethyl alcohol as recrystallization solvent. The method is economic and environmentally friendly because of the low price of amine A and small consumption of recrystallization solvent. Sample was characterized by ^1H NMR, UV, IR and GC-MS methods. Purifications of abietic acid with isopropylamine, cyclohexylamine, octadecyl primaryamine, di-n-butylamine, triethylamine, and amine A were studied. The effects of carbon numbers of amines and primary, secondary, tertiary amines on purifying process were analyzed. The abietic acid with purity of 90 % could be stored for 2 months at 5 kPa and - 15 ℃.
