Abstract
All of the dimethylene-interrupted methyl cis-octadecenynoate isomers, except the delta13c,17a isomer, have been prepared by partial hydrogenation of the corresponding methyl octadecadiynoate. Gas-liquid chromatographic analysis of the octadecenymoates has been carried out on Carbowax 20M, DEGA, DEGS, FFAP and Silar 10C stationary phases. The delta3,7 isomers decompose on chromatography. The equivalent chain lengths of all of the remaining methyl cis-octadecenynoates are reported.
摘要
除δ13c,17a异构体之外的所有亚甲基间断的顺式十八碳烯炔酸甲酯异构体，均通过相应的十八碳二炔酸甲酯的部分氢化反应制备而成。已在聚乙二醇20M、二乙二醇琥珀酸聚酯、二乙二醇琥珀酸酯、游离脂肪酸聚酯和Silar 10C固定相上对十八碳烯炔酸酯进行了气液色谱分析。δ3,7异构体在色谱分析过程中会分解。报告了所有其余顺式十八碳烯炔酸甲酯的等效链长。
