摘要： New, highly effective detergent/dispersants for use in spark-ignition fuels comprising Mannich condensation products formed from (i) at least one substituted hydroxyaromatic compound having on the ring both (a) an aliphatic hydrocarbyl substituent derived from a polyolefin having a number average molecular weight in the range of about 500 to about 3000, and (b) a C 1-4 alkyl; (ii) at least one secondary amine; and (iii) at least one aldehyde are described. Carrier fluids such as poly(oxyalkylene) compounds further enhance the effectiveness of these Mannich condensation products in minimizing or reducing intake valve deposits and/or intake valve sticking.

摘要： The present invention discloses a process for manufacturing an alkylphosphonate monoester. The process may comprise partially hydrolyzing an alkyl phosphonate diester with an alkaline compound in a first solvent to provide a reaction mixture, wherein the first solvent comprises a mixture of an alcohol and water. The reaction mixture may be diluted with a second solvent to provide an organic phase, wherein the second solvent comprises at least one non-polar organic solvent. The process may comprise acidifying the reaction mixture with an acid, wherein the organic phase includes an alkylphosphonate monoester.
