Problems solved by technology

However, practice has proved that some insurmountable shortcomings have also occurred in the process of using fat: the effect of using fat in young livestock and poultry is not obvious
[0005] At present, the synthesis of mono- and diglycerides of butyrate has not been reported at home and abroad.

Embodiment 1

[0024] Weigh 184g of glycerin, 141g of butyric acid, 7.4g of catalyst phosphoric acid, and 100ml of carbon tetrachloride with water agent, and add them to a 500ml three-neck flask equipped with a thermometer, a water separator and a reflux condenser, turn on the magnetic stirring, and heat up to reflux , when the temperature of the system rises to the highest temperature of 110°C, with the formation of water in the reaction, the temperature drops slowly, and when the amount of water in the water separator remains basically unchanged, the reaction is stopped, the reaction is refluxed for 2.5 hours, and the heating is stopped. Add zeolite and distill carbon tetrachloride to obtain crude product. The crude product was washed with weakly alkaline saturated saline for several times until the lower aqueous phase was alkaline, and the ester layer was poured out from the upper end of the separatory funnel, and dried in a drying oven for 3 h. After cooling, filter with a funnel plugged...

Embodiment 3

[0028] Weigh 184 g of glycerin, 123 g of butyric acid, 9.2 g of catalyst phosphoric acid, and 100 mL of water-carrying agent carbon tetrachloride, and add them to a 500 mL three-necked flask equipped with a thermometer, a water separator and a reflux condenser, and start magnetic stirring. Heating to reflux, when the temperature of the system rises to the highest temperature of 103°C, the temperature drops slowly with the formation of water in the reaction, and when the amount of water in the water separator remains basically unchanged, the reaction is stopped, the reaction is refluxed for 3 hours, and the heating is stopped. Add zeolite and distill carbon tetrachloride to obtain crude product. The crude product was washed with weakly alkaline saturated saline for several times until the lower aqueous phase was alkaline, and the ester layer was poured out from the upper end of the separatory funnel, and dried in a drying oven for 3 h.

Abstract

The invention discloses a synthesis method of functional feed additive butyric acid mono-and di-glyceride, comprising the following steps: heating and reflowing glycerol and n-butyric acid in the presence of phosphoric acid serving as a catalyst and carbon tetrachloride serving as a water-carrying agent; stopping reacting until the amount of the water in a water knockout drum is almost constant; distilling out the carbon tetrachloride to prepare a crude product; rinsing the obtained crude product by utilizing a saturated salt solution with the pH of 10 for many times so as to remove the reactant and catalyst which do no react; and separating and purifying until the low-layer aqueous phase is alkaline, thus obtaining the butyric acid mono-and di-glyceride. The method is simple and easy to control, and has the advantages that the reaction condition is safe and moderate, separation and purification can be carried out easily, and the steps are less.

Description

technical field [0001] The invention belongs to the field of preparation of nonionic surfactants for feed, in particular to a preparation method of functional feed additive butyric acid mono- and diglycerides. Background technique [0002] Butyric acid is an organic acid acidifier commonly used in the feed industry. In addition to the functions of seasoning and supplementing insufficient secretion of gastric juice, it can also regulate the balance of gastrointestinal microbial flora and provide rapid energy for intestinal cells It can promote the proliferation and maturation of gastrointestinal cells, enhance immunity and other special functions, and is considered as a potential substitute for antibiotics. [0003] At present, the feed industry generally has the purpose of adding oil to improve feed energy supply, improve livestock production performance and feed remuneration. Yet practice has proved that some insurmountable shortcomings have also occurred in the process of...
