Abstract
The methanolysis of jojoba oil has been studied in the presence of tin powder, dibutyltin diacetate (C4H9)2Sn(OOCCH3)2, dioctyltin diacetate (C8H17)2Sn(OOCCH3)2, dibutyltin oxide (C4H9)2SnO, dioctyltin oxide (C8H17)2SnO, diphenyltin oxide (C6H5)2SnO, dibutyltin chloride dihydroxide (C4H9)2Sn(OH)2Cl, butyltinhydroxide hydrate (C4H9)Sn(=O)OH.xH2O, Ni nanoparticles and Pd nanoparticles act as catalysts. Among these, 1 weight % of dibutyltin diacetate shows the maximum conversion. Then, methanolysis of sunflower oil, neem oil, rocket seed oil and linseed oil into methyl esters studied in the presence of 1% dibutyltin diacetate as a catalyst and was compared their percentage conversions. The experimental yield for the conversion of jojoba oil, sunflower oil, neem oil, rocket seed oil and linseed oil into biodiesel was found to be 71%, 51%, 50.78%, 40.90% and 39.66%, respectively. The experimental yield of the conversion of jojoba oil into methyl esters was found to be increased up to 96% by increasing reaction time, without emulsion formation. The synthesis of jojoba seed oil biodiesel (JSOB), soybean oil biodiesel (SOB), neem oil biodiesel (NOB), rocket seed oil biodiesel (RSOB) and linseed oil biodiesel (LSOB) was confirmed by NMR (1H &13C) and FT-IR analyses of biodiesel.
