ABSTRACT
Alkyd resin was prepared using the seed oil of water melon (Citrullus Lanatus). The extraction of the seed oil of Citrullus Lanatus was done by solvent extraction method using n-hexane as the solvent. The physicochemical properties of the oil were determined using standard analytical procedures, the result of the physicochemical properties of the oil is as follows; colour (yellow), specific gravity (0.9), saponification value (181mg KOH g-1). Iodine value (68.63g of iodine/10g of oil), Refractive index at 400C (1.45), Acid value (0.81mg KOH/g) and free fatty acid (12.1mg KOH/g). The result of the physicochemical properties of the oil revealed that the oil is a drying oil since its iodine value is less than 100. The percentage yield of alkyd resin based on the oil is 80%, this shows that the oil is ideal for the production of alkyd resin. The physicochemical properties of alkyd resin produced from the seed oil of water melon (Citrullus Lanatus) revealed that the alkyd resin has good viscosity (23% at 30oC), flexibility (flexible) adhesion (Hard) and drying properties (which involves hard dry (tested after 24hour) and surface dry (tested after 2hours)).
