IN-SITU METHOD FOR PREPARING HYDROLYZED ACYL HALIDE COMPOUND

摘要

An in-situ method for preparing a hydrolyzed, acyl halide-containing compound by combining a reactant including a plurality of acyl halide functional groups containing reactant, a tri-hydrocarbyl phosphate compound and water within a hydrocarbon or halogenated hydrocarbon solvent.

1. A method for preparing a reaction product comprising at least one acyl halide functional group and a carboxylic acid functional group in a solution comprising a hydrocarbon or halogenated hydrocarbon solvent having a water solubility of less than 800 ppm;
wherein the reaction product has a solubility limit of less than 1 weight percent in the solvent and is produced to a molar concentration greater than its solubility limit within the solvent while remaining soluble in solution, and wherein the solution comprises at least 80 v/v % solvent in combination with:
i) water at a molar concentration greater than its solubility limit within the solvent but less that its solubility limit with the solution,ii) a reactant comprising a plurality of acyl halide functional groups at a molar concentration less than its solubility limit within the solvent and at a molar ratio with water from 1:2 to 1000:1, andiii) a tri-hydrocarbyl phosphate compound at a molar ratio with the reactant from 100:1 to 1:1000 wherein the tri-hydrocarbyl compound is represented by: wherein R1, R2 and R3 are independently selected from hydrogen and hydrocarbyl groups comprising from 1 to 10 carbon atoms, with the proviso that no more than one of R1, R2 and R3 are hydrogen.
