Abstract:

with glycerol (0.5mol), butyric acid (0.4mol) as raw materials, carbon tetrachloride (25ml) as water-carrying agent, the amount of phosphoric acid (4.0% of glycerol) synthesis of glyceryl butyrate by catalytic esterification. The structure of the product was qualitatively analyzed by FT-IR. The results showed that the target product could be synthesized, and the content of monoglyceride was 60.2%. The synthesized butyrin Ester was used as emulsifier in microencapsulation of oil and fat, and good results were obtained.

Yu Jiqiang

Abstract:

The present invention relates to a preparation method of butyrin Ester, comprising the following steps: the first step, in a reaction vessel, P-toluenesulfonic acid is heated to carry out the reaction under the condition of passing nitrogen gas, and the generated water is discharged from the reaction vessel; When there is no more water discharged, the heating is stopped and the nitrogen gas is maintained; when the liquid in the reaction vessel is cooled, the nitrogen gas is stopped, and the liquid in the reaction vessel is the crude product; The second step, the crude product is repeatedly washed alternately with 0.5-1.0% NaOH solution and distilled water until the acid value of the crude product falls below 1mg; The washed crude product is put into a separating funnel, the oil phase liquid is separated; Anhydrous sodium sulfate is added to the oil phase liquid until no crystallization occurs, and the filtrate obtained by filtration is the final product. The present procedure to a method for preparing acids, p-toluenesulfonic acid under conditions of heated nitrogen gas through the reaction, and the resulting water discharge reaction vessel, the heating was stopped, purged with nitrogen and maintained; when the liquid within the reaction vessel was cooled, nitrogen gas was stopped, the resultant reaction liquid in the container as a crude product; the second step the crude The product was a concentration of 0.5-1.0 mass% NaOH solution and washed repeatedly with distilled water alternately, until the acid number of the crude product falls below 1mg; The crude product was washed into a separatory funnel, separated oil phase liquid; to the liquid phase unspecified, the resultant was filtered and the filtrate was the final product. After adopting the method of the invention, the obtained butyrin Ester has high purity, fast reaction rate and easy industrial production. With the process of this, the resulting high purity acid glycerides, and fast reaction rate, ease of industrial production.
