    • 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.
    • 本发明是一种生产特定硫酸盐的方法,包括以下步骤:将具有氧化丙烯基的特定起始化合物沿着反应管的内壁向下流动,在内部形成起始化合物的薄膜 反应管的壁,该管设置在包括两个或更多个温度控制的夹套的夹套系统中,其中温度控制流体可以流动,并且一起将SO 3气体输送到反应管以使起始化合物与 SO 3气体以获得硫酸化产物,并中和所得的硫酸化产物。 两个以上的夹套包括放置在上游部分的上游护套和沿起始化合物流动方向放置在下游部分的下游护套,并且在特定条件下使用。
