Paragraph 0016; 0020; 0021, (2017/07/19)
The invention discloses a preparation method of meat alcohol phosphate. The method includes the following steps of firstly, separately adding phosphorus pentoxide to phosphoric acid for reaction; secondly, adding muscle alcohol phosphate to reaction liquid in the first step to generate meat alcohol phosphate biopolymer; thirdly, adding water to reactant in the reaction liquid in the second step; fourthly, cooling the reaction liquid in the third step to the room temperature, adding solvent to obtain precipitates, conducting suction filtration, washing a filter cake with solvent, draining the filter cake, drying the filter cake at the temperature of 80 DEG C till the constant weight is reached to obtain a product, and conducting pressure reduction and concentration on a mother solution to obtain organic solvent and phosphoric acid. Raw materials in the synthesis method are easy to obtain, no excessive waste can be generated in reaction, organic solvent and phosphoric acid can be applied mechanically, pollution emission is greatly reduced, and the method is low in production cost, small in wastewater discharge, high in synthesis yield, suitable for industrial production, not high in reaction requirement, not high in corrosion to reaction devices and small in influence on the environment and human bodies.
