Embodiment 1
[0017] Mix the 1:4 chloroform and absolute ethanol, pour it into a 100 mL three-necked flask, and then use the dropping funnel to drop the mixed solution of chloroform and phosphorus trichloride with a volume ratio of 5:4. mL, use ice water to control the temperature at 6~8 ℃, start the stirrer, and dropwise addition is completed in about 1 h. Hydrogen chloride gas generated during the reaction was absorbed with 5% sodium hydroxide solution. After the reaction is complete, pour the reactant into a beaker, neutralize to pH=7~8 with 10% sodium carbonate solution, add deionized water to wash three times, separate with a separatory funnel, and distill under reduced pressure to obtain sub Diethyl Phosphate (C 2 h 5 OPHO C 2 h 5 ), the yield was 94.8%.
[0018] Add diethyl phosphite into a 250 mL iodine flask, add equimolar 10% ammonia water, and carry out ammoniation reaction in a water bath at 40 °C for 48 h to obtain ammoniated product C 2 h 5 OPHOONH 4 . Transfer the am...
