Abstract
PURPOSE: To obtain the titled compound useful as a solvent, catalyst, flame retardant, etc. in high yield and at a low cost, by reacting a readily available phosphoric acid with an alkyl halide in the presence of an amine.
CONSTITUTION: Phosphoric acid is reacted with an alkyl halide in the presence of an amine at 40W150°C to give an alkyl phosphate. The amine is a primary, secondary or tertiary amine or heterocyclic amine of formula III (R1, R2 and R3 are 1W10C alkyl, phenyl, aralkyl, etc.) and most preferably the tertiary amine. The method is much more inexpensive than the conventional method in which phosphorus oxychloride is used.
