ASTM standards for biodiesel

The physical properties of beef tallow i.e. methyl esters density, kinematic viscosity, cloud point, pour point, cold filter plugging point (CFPP), acid value, calorific value, and flash point, were within ASTM standards for biodiesel.

This research illustrates the results of a study on the synthesis of maleic anhydride-vinyl acetate copolymers (MAVA) with the monomer molar ratio of 1:1 by the radical polymerisation method in which benzoyl peroxide was used as a catalyst. The structure and composition of MAVA were characterised by FTIR, 1 H-NMR and 13C-NMR spectra. The molecular weight of the copolymers was determined by the viscosity method. The copolymers were then modified by the esterification reaction with hexadecanol - a long alkyl chain alcohol.
