Patent number: 4988817Abstract: 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.Type: GrantFiled: November 16, 1988Date of Patent: January 29, 1991Assignee: Lever Brothers Company, Division of Conopco, Inc.Inventors: Stephen A. Madison, Jeffrey Bonn, Eddie N. Gutierrez

Patent number: 4985561Abstract: A process is described for obtaining sulfophenyl quaternary ammonium or phosphonium substituted carbonic acid esters. These esters are prepared through sulfonation with sulfur trioxide of aromatic chloroformates followed by reaction of the sulfonated aromatic chloroformate with quaternary ammonium or phosphonium substituted alcohols. The resultant sulfophenyl esters are useful as bleach precursors in combination with peroxygen compounds such as sodium perborate or percarbonate.Type: GrantFiled: August 29, 1989Date of Patent: January 15, 1991Assignee: Lever Brothers Company, Division of Conopco, Inc.Inventors: Stephen A. Madison, Leonora M. Ilardi, Hans Cerfontain

Patent number: 4931563Abstract: A process is provided for obtaining sulfophenyl quarternary ammonium or phosphonium substituted carbonic acid esters. The important step in this process involves reacting a phenyl quaternary ammonium or phosphonium substituted carbonic ester with oleum that contains from 0.5 to 33% sulfur trioxide. Amounts in excess of 33% sulfur trioxide lead to increased reaction times and, eventually, unacceptable product conversons.Type: GrantFiled: November 16, 1988Date of Patent: June 5, 1990Assignee: Lever Brothers CompanyInventors: Stephen A. Madison, Leonora M. Ilardi
