Enzymatic synthesis of biodiesel from Jatropha tanjorensis Ellis and Saroja and its potential as biodiesel feedstock was written by Arun, K. P.;Ravichandran, N.;Devi, M. Nithya;Vajrai, R.;Brindha, P.. And the article was included in Asian Journal of Chemistry in 2016.Quality Control of 2-Ethylhexyl benzoate The following contents are mentioned in the article:
21St century has almost become “”reen century” with an increased demand for plant products (bioenergy-oil). Hence, to develop a natural biodiesel feedstock, common species of Jatropha in and around Thanjavur is selected based on its enriched monoalkyl ester content which could be a good source for generating biofuels. Tanjorensis seed oil were extracted and analyzed for its physico-chem. properties such as % free fatty acid, acid value iodine, peroxide, saponification values. P. aeruginosa crude lipase treated transesterification followed by GC-MS anal. of oil proved that oleic acid (37.3 %) and linoleic acid (33.3 %) were the principal fatty acids while palmitic acid and stearic acid being the major saturated fatty acids. Oil contents of Tanjorensis seed oil were comparable with the oil extracted from other species of Jatropha and were found to be close to oil from Jatropha curcas. Tanjorensis seed oil extracts could be useful in industrial applications and as a biodiesel feedstock. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Quality Control of 2-Ethylhexyl benzoate).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
