Abstract: PURPOSE:To carry out the sulfonation of an organic compound using diluted SO3 gas as a sulfonation agent, in high efficiency, by introducing raw liquid into a ring-shaped orifice under pressure to form a uniformized thin film and using SO3 gas after cooling in the middle part of the apparatus. CONSTITUTION:A plurality of reaction tubes 1 are vertically arranged in a ring-shaped space in a double cylinder closed reaction column containing an inner cylinder at the center. The inner cylinder plays the role of a flow channel of dilute SO3 gas. A raw material liquid is introduced under pressure to the top of the reaction tube 1, allowed to flow down from a ring-shaped orifice 2b along the inner wall surface of the reaction tube 1 to form a thin film and, at the same time, cooling water is circulated in the ring-shaped space between the reaction tube and the inner tube to cool the reaction mixture and diluted SO3 gas. The diluted SO3 gas is supplied through a nozzle 2a attached to the top of each reaction tube 1 to effect the sulfonation of an organic compound. The apparatus enables not only the sulfonation reaction but also a sulfonation reaction to form a sulfuric acid ester via O atom. The side reaction and coloring of product can be suppressed and the size of the apparatus can be reduced since the cooling means is placed at the center of the apparatus.
