Alkyd resins are the product derivation of polyacid and polyol modified with monobasic fatty acid through polycondensation. Over the recent years, alkyd resins are widely used as the binder for composite and film-forming agent in paints. Vegetable oils were being explored and evaluated to synthesis alkyd resin due to its biodegradability and renewability. Synthesis of alkyd resins involved the alcoholysis of the oil by the polyol (commonly glycerol) and followed by polyesterification with a polyacid (commonly phthalic anhydride). Generally, a homogeneous or heterogeneous base catalyst was used to carry out the reaction. Nanoparticles were said to be a promising catalyst and colloidal form of nanoparticles was discovered in this context. In this work, palm oil based alkyd resin was synthesized over Magnesium Oxide (MgO) nano sol. Colloidal MgO nanoparticles were synthesised in glycerol and subsequently was used in alkyd resin synthesis. The alcoholysis process was conducted in the presence of various concentration of MgO (0.01, 0.02, 0.04 and 0.06wt% w.r.t. palm oil) at 240oC. The monoglycerides yield was found to achieve up to 95% in 40 minutes reaction time for 0.04wt% MgO catalysed system.
