Abstract :With glucose as the starting material, sodium tripolyphosphate as the phosphorus acylating agent, and urea as the catalyst, glucose 1-phosphate was synthesized and its properties were analyzed. The synthesis conditions were selected according to the phosphorus content and optimized through the response surface methodology insert ignore into journalissuearticles values(RSM);, based on a 3-level, 3-variable Box--Behnken experimental design. The results showed that the phosphorus content of glucose 1-phosphate was 8.12% using a reaction temperature of 70 °C, a molar ratio of glucose to sodium tripolyphosphate of 1.54:1, and catalyst amount of 3.7 g. It coincided well with the experimental value insert ignore into journalissuearticles values(8.34%);. The structure of the product was confirmed by IR, UV, and 1H NMR spectra; electrical conductivity; TG; and DTA. The proposed method has high phosphorus content and low toxicity.
