METHOD OF PRODUCING FATTY ACID ESTERS FROM SQUASHED OILSEED Russian patent published in 2013 - IPC C11C3/00 A23K1/14 C10L1/02 C07C67/03 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved method of producing fatty acid esters, which are used as diesel biofuel, from whole oilseeds, involving the following consecutive steps: a) preheating unhulled and cleaned whole seeds; b) squashing the oilseeds together with their shells; c) drying the squashed seeds until achieving water and volatile substance content of 0.5-2.5%; d) re-esterification by bringing the squashed seeds into contact with an alcohol medium in the presence of a catalyst; e) separating the liquid and solid phases obtained from re-esterification; f) neutralising the liquid phase obtained at step (e); and g) removing alcohol and separating glycerol from fatty acid esters, which are then purified. The invention also relates to a method of producing an oil cake, meant for use as animal feed, from the obtained solid phase, which involves the following steps: 1) removing alcohol from said solid phase; and 2) adding glycerol obtained at step (g) of the method on any of the previous claims.

EFFECT: method of obtaining fatty acid esters from squashed oilseeds.
