Web8.3.3.2 Phthalic Anhydride Synthesis. ... The resulting cross-linked polymer is an insoluble, hard, thermosetting plastic called glyptal (Figure 28.12). Figure 28.12. Cross-Links in a Condensation Polymer. The reaction of 2 moles of 1.2,3-propanetriol and 3 moles of phthalic anhydride gives a cross-linked polymer called a glyptal. 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.
