摘要
本文采用超临界流体精密分离和硅胶吸附色谱相结合的分离方法,考察了南阳、南充两种地蜡的化学组成与结构上的差别,并为窄馏分地蜡的生产提供了一种新方法。
Supercritical fluid precise fractionation and slilca gel adsorption chromatograph are used in combination to investigate the differences in chemical composition and structure between two commercial ceresins produced from Nanyang and Nanchong crude oils respectively. A novel method to produce new narrow fraction ceresin products is proposed.
