Abstract

Vegetable oils are rich in unsaturated bonds that can be converted to epoxidized oleic acid. They are considered sustainable, renewable, and also environmentally friendly. To date, there is a paucity of studies on production of dihydroxystearic acid (DHSA) using an eco-friendly ion exchange resin as it is not fully utilised. As a result, the aim of this study is to elucidate the mechanism of ring-opening by hydrolysis for the production of DHSA using amberlite IR-120H as a catalyst. The process of epoxidizing oleic acid involved the in situ generation of performic acid, which was then used to convert oleic acid into epoxidized oleic acid. This performic acid was created by combining formic acid, serving as the oxygen carrier, with hydrogen peroxide, acting as the oxygen donor. Under optimal conditions, the maximum relative conversion of oleic acid to oxirane was attained, with up to 85 %. Overall, DHSA with a high hydroxyl value (182 mg KOH/g), was successfully produced from oleic acid using in situ hydrolysis of epoxidized oleic acid.
使用离子交换树脂催化油酸环氧化,然后进行原位开环水解的可持续方法
植物油富含不饱和键,可转化为环氧化油酸。植物油被认为是可持续、可再生和环保的。迄今为止,使用环保型离子交换树脂生产二羟基硬脂酸(DHSA)的研究还很少,因为它还没有得到充分利用。因此,本研究旨在阐明使用琥珀岩 IR-120H 作为催化剂生产 DHSA 的水解开环机理。油酸的环氧化过程包括就地生成阳起酸,然后用阳起酸将油酸转化为环氧化油酸。作为氧载体的甲酸与作为氧供体的过氧化氢结合生成了执行酸。在最佳条件下,油酸与环氧乙烷的相对转化率最高可达 85%。总之,利用原位水解环氧化油酸的方法,成功地从油酸制备出了羟值较高(182 毫克 KOH/克)的 DHSA。
