Abstract: ALKENYL SULFOSUCCINIC ANHYDRIDES, ACIDS AND ALKALI AND AMINE SALTS THEREOF AND THEIR PREPARATION BY REACTING ON ALKENYL SUCCINIC ANTHYDRIDE WITH SULFUR TRIOXIDE IN AN ANHYDROUS SOLVENT REACTION MEDIUM TO FORM THE ALKENYL SULFOSUCCINIC ANHYDRIDE WHICH IS CONVERTED TO THE ACID OR SALTS BY REACTION WITH WATER OR AQUEOUS BASE SOLUTIONS. THE COMPOUNDS ARE USEFUL AS SURFACE TENISON REDUCING AGENTS, ESPECIALLY ADAPTED FOR INCORPORATION IN ACID PLATING BATHS.

Abstract: A process is disclosed which comprises the steps of introducing a stream of the organic liquid onto a plurality of rotating reacting surfaces, rotating the reacting surfaces at a velocity such that the organic liquid is continuously formed into a thin film on each reacting surface and is continuously moved as a thin film towards the periphery of each reacting surface by centrifugal force, depositing over each thin film a substantially undiluted stream of a gaseous medium, reacting the organic liquid and gaseous medium on said rotating reacting surfaces, maintaining the pressure during reaction at subatmospheric levels, moving the resulting reaction products in a radially outward direction along each reacting surface and collecting said reaction product. An apparatus for carrying out such process is also disclosed.
