Preparation of Acrylated Epoxidized Soybean Oil with Excellent Properties

In this paper, a kind of abundant and environment-friendly material—epoxidized soybean oil (ESO) was chosen to be esterified with acrylic acid to produce acrylated epoxidized soybean oil (AESO). By studying the influence of various factors including feed rate, reaction temperature, feed ratio, catalyst and inhibitor on the reaction, we got the optimal synthesis conditions: feed ratio is 1.25:1; reaction temperature is 120 °C; feeding time is about 2.5h;the dosage of the inhibitor (TBC) is 0.15 % and the catalyst (Triphenylphosphine oxide) is 1.5 %. The AESO we prepared has low viscosity, low skin irritation, excellent pigment wetting characteristics and so on. It can also be widely used in the manufacture of coating, printing ink, paint, etc.
