Abstract

The invention discloses a process for the production of monoglycerides by glycerolysis of methyl ester derived from animal or vegetable fat and oils which includes mixing a surplus of 0.1 to 3 moles of glycerols in relation to methyl ester, subjecting the reaction mixture to a reaction temperature between 130 to 160 at a vacuum of 200 to 400 mbar, adding of alkaline catalysts, stopping the reaction by fast cooling of the reaction mixture and the destruction of the alkaline catalyst when the quantity of glycerides has reached a concentration of mono and diglyceride of 40 to 60%, leaving the catalyst in the reaction mixture to catalyse the reaction downstream in a reactor, separating the surplus methyl ester and glycerol by distillation and stopping the reaction by fast cooling of the reaction mixture with reactor and the destruction of the alkaline catalyst when the quantity of glycerides has reached a concentration of 40 to 60% and the ratio of concentrations of mono and diglyceride lies between 3 to 10.
