Dalvi, Sanjaykumar published the artcileBiodiesel (fatty acid methyl ester) from Chlorococcalean Chlorella vulgaris by single step in-situ transesterification, Name: Methyl octanoate, the main research area is fatty acid methyl ester transesterification algae assessment.
To study the single step in-situ transesterification process for synthesis of fatty acid Me ester (biodiesel) from microalgae biomass Chlorococcalean Chlorella vulgaris. The growth and lipid productivity of an isolated microalgae C. vulgaris were studied under Chu’s 10 modified media under phototrophic cultivation conditions. In-situ transesterification of this dry biomass with methanol in presence of base catalyst at 60° C was carried out to investigate the fatty acid Me ester’s biochem. composition by FTIR & anal. performed using GCMS technique. The cetane number was also calculated The biodiesel fraction from C. vulgaris biomass was found to be 85.58%. The 43.40% lipid fraction was obtained from the biomass of C. vulgaris. In the in-situ transesterification process, the optimal concentration of potassium hydroxide (KOH) and methanol yields an 85.58 percent biodiesel fraction. The presence of lipid compounds and the biochem. composition of fatty acid Me ester were verified with the help of FTIR spectral anal. The gas chromatog.-mass spectrometry anal. explores the fatty acid Me ester profile, which comprises 29.05% and 56.54 percent saturated and unsaturated FAMEs. Through GCMS, the fatty acid Me ester composition of C. vulgaris microalgae species was revealed through six types of fatty acid Me esters, of which 54.95%, 11-octadecenoic acid Me ester, is the dominant one. The cetane number of C. vulgaris biodiesel was determined to be 67.726; this is comparable to diesel fuel according to ASTM-D613, and the presence of a higher fatty acid Me ester composition indicates favorable biofuel qualities. The calculation of cetane number by theor. method and affirmation of ecofriendly single step in-situ transesterification method for biodiesel production
Indian Journal of Science and Technology published new progress about Biodiesel fuel. 111-11-5 belongs to class esters-buliding-blocks, name is Methyl octanoate, and the molecular formula is C9H18O2, Name: Methyl octanoate.
