Use of amine oxide in the H2O2 oxidation of aliphatic mercaptan to sulfonic acid |
摘要 |
Hydrocarbyl mercaptans are oxidized to sulfonic acids by reaction with aqueous hydrogen peroxide in the presence of an inorganic base (e.g. sodium hydroxide) and a tert-amine oxide. The product is in the form of a sulfonate salt. The reaction rate is increased and undesirable free-oil by-product is decreased by the inclusion of the amine oxide catalyst.
