Organic compounds in liquid form are sulphonated or sulphated by passing gaseous SO3 in an inert gas in the form of a sheet-like gas stream of substantially rectangular cross-section at least three times as wide as thick, together with the organic compound in the form of an annular stream not more than about 0.1 inch thick, into an elongated reaction zone of cross-section substantially the same as the gas stream, so that a film of liquid flows down the periphery of the reaction zone and surrounding the gas stream, the organic compound being cooled prior to, and during the reaction, and the sulphonated or sulphated compound being finally separated from the gas mixture. The process is applicable to any compound known to be sulphonatable or sulphatable by SO3, e.g. fatty alcohols (e.g. lauryl, myristyl and cetyl) and ethoxylated fatty alcohols and alkyl phenols, or olefins (e.g. tetradecene, hexadecene), aromatic compounds and alkylated aromatic compounds (e.g. toluene, ethylbenzene and dodecylbenzene). |
