Alkyd Resins Based on Waste Cooking Oil and Crude Glycerol

Abstract

Two kinds of short oil alkyd resins were obtained for the present investigation. The first one was prepared on the basis of waste cooking oil, crude glycerol and phthalic anhydride while the second one was reference sample obtained from refined sunflower oil, pure glycerol and phthalic anhydride. The waste cooking oil was preliminarily treated by adsorption with zeolite. The alkyds were obtained by alcoholysis under microwave heating. The chemical bonds in them were confirmed by 1H NMR. Some basic characteristics of the alkyd resins obtained were compared. The results indicated that the alkyd resin based on waste cooking oil, crude glycerol and phthalic anhydride can successfully replace the reference resin for production of dyes and lacquers for which the requirements for color brightness are not so strong.
