Synthesis of acrylated epoxidized biobased resin from groundnut seed oil

Abstract

In this study, groundnut seed oil was epoxidized in situ using hydrogen peroxide (30%) and formic and acetic acid. The reaction conditions were monitored at a temperature of 70oC, stirring speed of 750 rpm and time of 6 hours. After epoxidation, a further modification was done using acrylic acid in the presence of hydroquinone at a temperature of 120oC. Comparatively, peroxyformic acid performed more effectively than the peroxyacetic acid during epoxidation with an iodine value (26.4 gl/100g oil) and oxirane content(3.27%). FTIR analysis of the raw, epoxidized, and acrylated groundnut seed oil indicates that they were suitably functionalized.
