摘要
针对传统松节油聚合工艺所得产品萜烯树脂中催化剂残留量较高的问题,进行了工艺技术改良,以氯硅烷作为助催化剂取代了毒性高、易残留的三氯化锑。新工艺在降低产品中残留催化剂方面功效显著,所得产品中氯元素含量低于100 mg/kg,金属铝元素含量低于5 mg/kg,不含金属锑元素,其质量指标符合美国FDA标准对作为食品添加剂使用的萜烯树脂的技术要求。
To reduce the contents of catalysts remaining in terpene resin produced by the traditional method, a primary improvement for its preparation process was put forward, i, e. , SbCl3, a kind of Lewis acids with high toxicity as the co-catalyst in the reaction, was replaced by TMCS. The new process has been proved that it had a remarkable effect on decreasing the residual quantity of catalysts. The obtained products usually have excelleut quality and the contents of chlorine and aluminum in it are lower than 100 mg/kg and 5 mg/kg respectively. There is no antimony existing in them. It is considered that terpene resins from new process could serve as food additives according to FDA standard.
