查询词典 siccative

The results indicate that it is possible to identify and distinguish these siccative oils because the unsaturated acid had changed into azelaic due to oxidation and polymerization during the drying process to make the chromatogram of siccative oils have a typical peak of C9 compound and provide a finger marker of m/z 217, and the concentration ratio of palmitic acid to stearic acid remains constant with time to facilitate the differentiation of oils.

分析时采用了热裂解与甲基化同时进行的技术。分析结果显示，4种干性油的不饱和脂肪酸在成膜后的甲基化产物均为壬二酸二甲酯，离子质量与离子电荷量比值为217，是干性油的特征检测峰。4种油中不同含量的软脂酸和硬脂酸在干性油成膜前后的比值不变，为干性油的甄别提供了可能性。
