Problems solved by technology

Use P 2 o 5 For phosphorylation, P 2 o 5 The feeding method is still in powder form. Due to its strong moisture absorption and easy agglomeration, it will also dehydrate and carbonize the reaction material, which will affect the progress of the reaction.
Although some people have used organic solvents such as CCl 4 , benzene, etc. will P 2 o 5 Dissolved, but actually not dissolved but added after dispersion, but due to the low boiling point of this type of solvent, it is easy to volatilize during the reaction and pollute the environment, and it must be removed after the reaction, which increases the operating procedures

Abstract

The invention is a manufacturing method for phosphate textile assistants. At first, the P2O5 is added into high molecular aliphatic hydrocarbon and its derivant solvent of mineral oil long carbon chains or plant oil dispersing solvent, they are blended evenly to be used as phosphorylation agent; castor oil or dewatered wool grease are heated to 30-60 degrees and adds in phosphorylation agent, adds in water to hydrolyze them after the heating reaction to produce acid phosphate ester; decreases the temperature to below 50 degrees, then adds in natrium oxyhydrogen to neutralize, heats up and stirs, adds in water to control the solid content between 45%-85%.

Description

technical field [0001] The invention relates to a preparation method of a light spinning auxiliary agent, in particular to a preparation method of a phosphate ester light spinning auxiliary agent. Background technique [0002] There is little research on the synthesis and research of phosphoric esters, especially the selection of phosphorylation reagents in the synthesis of phosphoric acid esters and the greening of phosphorylation methods. Commonly used phosphorylating agents are pyrophosphate, P 2 o 5 , POCl 3 , PCl 3 etc., due to POCl 3 , PCl 3 HCl is produced in the reaction, polluting the environment, and the phosphorylation of pyrophosphoric acid should be carried out under xylene azeotropic dehydration. Widely used in industry P 2 o 5 Phosphorylation is carried out. Use P 2 o 5 For phosphorylation, P 2 o 5 The feeding method is still in powder form. Due to its strong moisture absorption and easy agglomeration, it will also dehydrate and carbonize the reac...
