WebThis research presents the possibility of producing polyester (glyptal), which is a widely used coating material, from glycerol by esterification using phthalic anhydride. Esterification reaction of phthalic anhydride and glycerol to produce glyptal can be catalyzed by Lewis acid provided by either homogeneous or heterogeneous catalyst. http://www.scirj.org/papers-0919/scirj-P0919703.pdf Webalkyd resin, a complex oil-modified polyester that serves as the film-forming agent in some paints and clear coatings. Developed in the 1920s, alkyd-based enamel paints were once one of the most important types of surface coating. Owing to their incorporation of volatile organic solvents and to their low durability on exterior surfaces, they have yielded … martin camilleri
