Latest Patents
Imamura's latest patents include a sulfonation apparatus and a process for sulfonation. The sulfonation apparatus features a design that incorporates multiple vertical first-stage reaction tubes. In this apparatus, the sulfonatable material and an SO.sub.3 -containing gas are flowed upwardly from the lower ends of these tubes. Additionally, a single vertical second-stage reaction tube is utilized, where the reaction products from the first-stage tubes are combined and flowed downwardly with fresh SO.sub.3 -containing gas to complete the sulfonation reaction. The process for sulfonation involves a two-stage reaction using an SO.sub.3 -containing gas. The first-stage reaction is conducted by flowing the organic compound and the SO.sub.3 -containing gas in parallel flow relation into vertically positioned cylinders. The second-stage reaction collects the first-stage product, adds fresh SO.sub.3 -containing gas, and flows the mixture downwardly into another vertically positioned cylinder.
