Yield:1623-19-4 152 g

Reaction Conditions:

with aluminum (III) chloride;ammonium dihydrogen phosphate at 30 - 80; for 9 h;Temperature;Reagent/catalyst;

Steps:

1-4 Example 1
To have a reflux condenser,A dry 1000ml three-necked flask with thermometer and exhaust gas absorption device was charged with 229.5g (3mol) of 3-chloropropene,115 g (1 mol) of ammonium dihydrogen phosphate and 2.3 g of anhydrous aluminum trichloride as the catalyst.Under stirring,React at a temperature of 30 to 45°C for 6 hours.There is basically no reflux in the reflux condenser,Then increase the reaction temperature to 70-80°C and continue to keep the temperature for 3 hours.The exhaust gas is absorbed into hydrochloric acid with water.After the reaction, it is cooled to room temperature and filtered.The filtrate is crude triallyl phosphate,Then carry out vacuum distillation,Collect 120130/10mmHg fraction,152 g of triallyl phosphate was obtained,The purity of the product is 99.3%.
