The nucleophilic ring opening of epoxy fatty esters was carried out using the amino-1,2,4-triazole to yield substituted derivatives of β-amino alcohol. The synthesis of the substituted beta amino alcohols has been achieved by refluxing equimolar quantities of long chain epoxy esters (epoxy fatty esters) and 4-amino-1,2,4-triazole in dichloromethane to yield following compounds, methyl 10-(4'-am...

barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. their reduction with zinc and hydrochloric acid in methanol yielded the narylmethylcysteines ?9a-c?. these can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?reaction of n, n'-carbonyl diimidazole (im co...

The fuel qualities of several biodiesels containing highly saturated, mono, and poly unsaturated fatty acids, as well their combustion exhaust emission characteristics, were studied. Six biodiesel samples divided into two groups based on acid composition, including group 1 (coconut, castor, jatropha) II (palm, karanja, waste cooking oil biodiesel). All fuels (in both groups) tested in a single-...

Mycolic acids were detected in both reference strains and clinical isolates of mycobacteria using gas chromatography of fatty acid methyl esters prepared by acid methanolysis. The methyl esters were extracted with hexane, concentrated, and analyzed with a gas chromatograph by using two different injector temperatures. When the samples were analyzed at high injector temperatures of 300 to 350 de...

Jatropha curcas L., a drought tolerant, monoecious perennial shrub, has gained attention in the tropics and sub-tropics during the past decade as a potential biodiesel crop. Adequate genetic diversity for key agronomic traits is of fundamental importance in crop improvement programmes particularly for crops such as J. curcas, which are in the early stages of domestication. In J. curcas, genetic...

Bio-diesel the mono-alkyl esters of vegetable oils can serve as sustainable energy resources alternative to depleting fossil fuels and has gained more importance due to its clean environmental benefits, renewability and biodegradability. The proposed paper highlights the results of experimental investigations on the scope of utilizing biodiesel manufactured from Polanga and Jatropha oils as an ...

Biodiesel research has been carried out via transesterification. However, biodiesel products (methyl esters) have not encountered new insights, because feedstocks explored and studied. Various optimum conditions on transesterification reaction could produce different methyl ester type with compound. So, this review describes various oil feedstock that were to find insights about type. The took ...
