Huang, Rui published the artcilePhysicochemical characterizations of microalgal methyl esters extracted with hexane and refined by vacuum distillation at different temperatures, Recommanded Product: Methyl decanoate, the main research area is hexane microalgal methyl ester vacuum distillation.
To prepare quality biodiesel from microalgal lipids in pilot-scale reactors, Me esters from microalgal cells were extracted with hexane after direct transesterification and then refined by vacuum distillation The refined Me esters were comprehensively characterized via gas chromatog.-mass spectrometry, Fourier transform IR spectroscopy, NMR, and thermogravimetric anal. The Me ester refined at 255°C-259°C was found to be the ideal fuel with a high fatty acid Me ester content of 94.6%, a low combustion activation energy of 42.1 kJ/mol, and a proper carbon-chain length distributed in C14-C18. Impurities extracted with hexane, such as alkanes and short-chain esters, were separated at 105°C-254°C owing to their low polarity and mol. weight Highly unsaturated Me esters with a long carbon-chain were collected at 260°C-280°C owing to their high b.p. Separation of alkanes, short-chain esters, and highly unsaturated Me esters through vacuum distillation effectively improved the properties of the Me esters extracted with hexane as a fuel and enhanced the economic feasibility of microalgal lipids.
Fuel published new progress about Activation energy. 110-42-9 belongs to class esters-buliding-blocks, name is Methyl decanoate, and the molecular formula is C11H22O2, Recommanded Product: Methyl decanoate.
