Abstract
Wax esters of C28-C44 chain-lengths, and containing 0-7 double bonds, were characterized with equivalent chain lengths [ECL] obtained by GC using a cyanosiloxane, Silar 10C. The ECL of the unsaturated wax esters is significantly dependent upon the column temperature, and selection of an appropriate column temperature permitted adequate resolution of critical pairs differing in the degree of unsaturation or the position of the double bonds.
摘要
链长为C28 - C44且含有0 - 7个双键的蜡酯，通过使用氰基硅氧烷Silar 10C的气相色谱法获得的等效链长[ECL]进行表征。不饱和蜡酯的ECL显著依赖于柱温，选择合适的柱温能够充分分离双键饱和度或位置不同的关键对。
