摘要
将Span－60水解为山梨醇酐和硬脂酸，再将硬脂酸甲酯化，采用气相色谱法测定硬脂酸的量，并根据Span－60的结构式，计算SOP型合成纤维油剂中该物质的含量。测试方法简便易行，测定结果准确、精密度高，令人满意。
Sorbitanmonosteatate was decomposed into sorbitan and stearic acid. The stearic acid was esterif icated by methyl. The methylstearate was detected by gas chromatography. According to the componsition of sorbitanmonostearate, the content of Span - 60 in SOP agent was calculated. The method was simple, with results right, good reproducibility and satisfactory.
