Acetylation of glycerol and so-called "glycerol layer" that forms after transesterification of triglycerides of rapeseed oil by methanol in the presence of sodium hydroxide was investigated. Kinetics of acetic acid accumulation and reduction of glycerol concentration in the presence of acid catalyst KU-2 was studied. Optimal conditions at that conversion of glycerol is 100% and degree of its acetylation - more than 95% were found. Cetane number (CN) and limiting temperature of filtration (LTF) of three samples (1 - without AGL, 2 - 5% AGL, 3 - 9,5% AGL) were determined. It is found that CN of samples are 50, 52, 45 and LTF are -3, -1 and -3, respectively, that satisfies the standards of Ukraine. Analysis of the influence of raw materials nature, reagents and catalysts on the rate and selectivity of transesterification triglycerides of vegetable and animal origin by alcohols in presence a caustic soda is done on the basis of literature data and authors' research
