| Abstract: | A method was presented to synthesize castor oil phosphate in this paper,in which P 2O 5 was dispersed in a kind of non toxic compounded solvent and slow released into the reaction liquid.Comparing with the conventional method of direct application of P 2O 5 powder,this method improved the conversion rate of P 2O 5 by 6 0%,and the proportion of phosphoric acid monoester(MAP) in the product x (MAP) increased from 52.0% to 71 6%. |
