Abstract
Urea phosphate was prepared from wet process phosphoric acid.A high activator RX-III was adopted to simplify the purification and increase the purity of product.Result showed that the optimal condition was as follows: molar ratio of urea to phosphoric acid 1.1:1,amount of RX-III 0.15% and reaction at 75 oC for 0.7 h,with the yield of 80.5%.
