METHOD FOR PREPARING ARYL POLYOXY ALKYL QUATERNARY AMMONIUM COMPOUND

A method for preparation of an aryl poly(oxalkyl) quaternary ammonium compound is provided, said method comprising steps of: 1) reacting a phenol with a dihalopolyalkylene ether under the action of a phase transfer catalyst, to obtain an arylpoly(oxalkyl) halide; 2) reacting said arylpoly(oxalkyl) halide with an amination reagent under the action of a phase transfer catalyst, to obtain an arylpoly(oxalkyl) amine; 3) reacting said arylpoly(oxalkyl) amine with an alkylation reagent, to obtain an aryl poly(oxalkyl) quaternary ammonium compound; wherein R1 is H or a C1 to C16 alkyl group, located in the ortho, meta or para position; n is an integer of 2 to 6; R2 is H or a C1 to C16 alkyl group; R3 is H or a C1 to C16 alkyl group; R4 is a C1 to C16 alkyl group; X1 is Br or Cl; X is Cl, Br, or I. The preparation method according to the present invention requires low temperature and low pressure, the reaction time is short, and an overall yield can reach 75%. The operation is simple, the cost is low, and the product can be separated easily and have a purity of pharmaceutical grade, thereby facilitating the large-scale production.

Method for preparing arylpoly(oxyalkyl) amines

The invention pertains to a process for preparing an arylpoly(oxyalkyl)compound, wherein the process involves reacting a phenol with a halohydrin, and reacting the reaction product with an amino alkyl halide. The invention seeks to provide a less hazardous alternative to conventional preparation processes where arylpoly(oxyalkyl)compounds are made starting from an extremely toxic and hazardous dihalogeno-polyalkylene ether. The preferred arylpoly(oxyalkyl)compound is benzethonium chloride.
