Distribution of Ethyl Esters and Glycerides between ester and glycerol phases after ethanolysis of rapeseed oil

Popis výsledku v původním jazyce

The distribution of ethyl esters, triglycerides, diglycerides and monoglycerides between the ester and glycerol phase were investigated after the ethanolysis of rapeseed oil at various reaction conditions. The determination of these substances in the ester and glycerol phase was based on the GC chromatography method. The amount of ethyl esters in the glycerol phase was unexpectedly high and therefore the effect of a heterogeneous reaction mixture composition on this amount was investigated. The distribution coefficients and weight distributions of each investigated substance were calculated and compared with each other. The distribution coefficients increase in this sequence: monoglycerides, diglycerides, ethyl esters and triglycerides. Soaps and monoglycerides in the reaction mixture cause worse separation of ethyl esters from the reaction mixture.
