application | dimethyl acetone phosphonate is an organophosphorus compound, which is an important chemical substance and exhibits many excellent properties. It is widely used in agriculture, medicine, industry and other aspects. |
preparation | heat the dry and clean 500mL coil to 135 ℃, take 1000g(0.7 eq.10.81mol) of chloroacetone (boiling point 117~119 ℃ under standard atmospheric pressure) and place it in beating bottle a, add 4000g of toluene to dilute it, take 1878g(1.0 eq.15.13mol) of trimethyl phosphite (boiling point 112 ℃ at standard atmospheric pressure) and place it in beating bottle B, add 3122g of toluene to dilute it, start beating after the coil temperature is stable, pump A (toluene solution of compound 6):12.5 g/min, pump B (trimethyl phosphite):12.5 g/min. The residence time is 20min and the reaction pressure is 0.5~2.0Mpa.. The discharge port is directly connected to the film evaporation device, the pressure is controlled by 4~10 × 102Pa, the temperature is 60~70 ℃, and finally 1230g of dimethyl acetonyl phosphonate (boiling point 85~88 ℃,666Pa) is obtained, and the yield is 88%. 1H NMR(400MHz,CDCl3):δ3.78(d,6H,J = 11.0Hz,),3.07(d,2H,J = 22.8Hz,),2.29(s,3H). |
