Abstract: A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. The process can be carried out in a distillation column reactor wherein the acid catalyzed reaction and fractional distillation are carried out simultaneously. Suitable alkylating agents include alcohols and olefins.

Abstract: The present invention relates to a process for producing an organic acid or its derivatives, which comprises oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst and an oxidant. In particular, the present invention relates to a process comprising oxidation of a hydrocarbon substrate in the presence of a homogeneous MC-type catalyst selected from Co/Br, Mn/Br, Co/Mn/Br and Co/Mn/M/Br and an O2/CO2 mixed gas oxidant where the partial pressure of O2 is controlled to 30-40%, thereby improving the oxidation rate, the conversion, the selectivity and the yield even under milder conditions. Especially, the present invention remarkably reduces down to a negligible level the production of color impurities and other impurities such as 4-CBA and p-toluic acid, which had been conventionally removed by hydrogenation reduction. Further, the loss in acetic acid solvent due to combustion can also be drastically decreased using the method of the present invention.
