Abstract
Neem seed (Azadirachtaindica) oil was extracted from its oil seeds by cold maceration using petroleum ether (60-80%) as solvent. The oil obtained was characterized and the acid value, saponification value, iodine, refractive index, peroxide value and viscosity were found to be 17.40(mg/KOH), 213.18 (mg/KOH), 75.26 (Wij’s), 1.462, 7.82 (mg/kg) and 88.43(cP) respectively. The oil was epoxidized at 40°C using formic acid generated in situ. The epoxidized oil was characterized and the acid value, saponification value, iodine value and refractive index were found to be 29.6 (mg/KOH), 112.7 (mg/KOH), 7.1Wij’s and 1.368 respectively. The epoxidized oil was used to cross-link prepared soybean adhesive. FTIR and Water Resistance analysis of the modified and unmodified soybean adhesive indicates that the modified soybean adhesive shows better performance in terms of bond strength and water resistance.
