Proceso para producir una sal de éster de ácido sulfúrico

摘要

The present invention is a method for producing a specific sulfate, including steps of: feeding a specific starting compound having an oxypropylene group as a flow running down along the inner wall of a reaction tube to form a thin film of the starting compound on the inner wall of the reaction tube, the tube being provided in a jacket system including two or more temperature-controlled jackets in which a temperature-controlling fluid can flow, and together feeding the SO 3 gas to the reaction tube to react the starting compound with the SO 3 gas to obtain a sulfated product, and neutralizing the resultant sulfated product. The two or more jackets include the upstream jacket placed on the upstream part and the downstream jacket placed on the downstream part in the direction of the flow of the starting compound, and are used under specific conditions.
