| 摘 要： | 采用基团贡献法计算了单个脂肪酸甲酯的溶解度参数,发现脂肪酸甲酯的溶解度参数随着碳链的增长而降低,而碳链不饱和度的增大对其影响有限。测定了几种脂肪酸甲酯的KB值,考察了生物柴油萃取废水中苯酚的萃取性能,并将其与脂肪酸甲酯的溶解度参数进行了比较,结果显示利用基团贡献法计算得到的脂肪酸甲酯的Hansen溶解度参数可以很好地反映脂肪酸甲酯的溶解性能。在此基础上,比较了脂肪酸甲酯与常用有机溶剂、常见有机污染物的溶解度参数,结果发现,脂肪酸甲酯与常用有机溶剂、常见有机污染物具有相近的溶解度参数,脂肪酸甲酯可以作为一种性能优良的绿色溶剂,替代常用的有机溶剂广泛应用与工业清洗、废弃物处理等方面。

| Abstract: | Solubility Parameters of fatty acid methyl esters(FAMEs) were calculated by group contribution methods.Results showed that solubility parameters of FAMEs increased with the chain length,but were not affected by the degree of unsaturation.KB values and extraction ability of FAMEs for pyridine in water were measured and compared with solubility parameters.It was shown that the consistency existed among KB value,extraction ability and solubility parameters.Hansen solubility parameters of FAMEs calculated by gr... |
