Synthesis of dihydroxystearic acid for palm oil-derived oleic acid via sustainable epoxidation and subsequent ring-opening using amberlite IR-120H ion exchange resin catalyst / Siti Mariam A. Rahman

Vegetable oils have high content of unsaturated bond that can be converted into epoxidized oleic acid thus they are considered sustainable, renewable, and also an environmentally friendly. Many commercial epoxides in the market are mainly based on petroleum and animals which are not environmentally...
