A new family of sulfur-containing plasticizers derived from fatty acids has been developed. The synthetic approach is based on the thiol–ene addition of alkyl thiols to the double bond of technical oleic acid, followed by oxidation of the sulfide group to either sulfoxide or sulfone groups. It has been found that both sulfide and sulfoxide derivatives are not suitable as plasticizers due to their unpleasant
已经开发了一种新的衍生自脂肪酸的含硫增塑剂。合成方法是基于烷基硫醇的硫醇-烯加成到工业油酸的双键上,然后将硫化物基团氧化为亚砜或砜基团。已经发现,由于硫化物和亚砜衍生物具有令人不愉快的气味和有限的热稳定性,因此它们都不适合用作增塑剂。但是,砜衍生物无味,热稳定,并显示出与已建立的PVC增塑剂类似的增塑性能,例如环己烷1,2-二羧酸二异壬酯(CHAT)和邻苯二甲酸二异壬酯(VESTINOL®9)。据报道,广泛的应用测试证明了这一结论。此外,
