从岭南花椒根得到一种C_(18)酸为主的混合羧酸。用复分解法制得其混合稀土盐。实验表明,后者具有较高的涂料催干性能并能增强涂料膜的耐水性,具有一定的实用价值。本文在综合利用植物资源方面是一个尝试。
A mixed carboxylic acid mainly composed of C_ (18) acids was obtained from the roots of Lingnan. The use of complex decomposition of the mixed rare earth salt. Experiments show that the latter has high drying performance of the coating and can enhance the water resistance of the coating film, which has a certain practical value. This article is an attempt to comprehensively utilize plant resources.
