  • Patent number: 4988817
    Abstract: A process is provided for obtaining quaternary ammonium or phosphonium substituted carbonic acid esters. The first step involves reacting the hydroxyl predecessor compound of the ester with phosgene in an aprotic organic solvent to obtain a solution of chloroformate/hydrogen chloride complex. In a second step, the chloroformate/hydrogen chloride complex in solution is admixed with a salt whose conjugate anion, normally a phenol sulfonate, has structure L. During the admixing step, pH is maintained no lower than 6 until all reactants have been combined to form the product ester. Thereupon, pH is lowered to less than 5.5 to stabilize product against hydrolysis.
