Abstract
Organic liquids are continuously sulphonated or sulphated by continuously introducing a stream of the organic liquid into a reaction zone, without any addition of sulphuric or other acid, and intimately mixing said liquid with a continuously introduced stream of a mixture of sulphur trioxide vapour and inert gas, which contains between 3 and 40 per cent by volume of sulphur trioxide vapour, the molecular ratio of sulphur trioxide to organic liquid being between 1.0:1 to 1.5:1, the temperature in the reaction zone being 32-60 DEG C., the pressure 0 to 100 p.s.i.g. and the mean residence time of the reactants in the reaction zone being not more than 10 minutes. The reactants may be intimately mixed in a reactor as described in Specification 799,039. Suitable liquids which may be subjected to the sulphonation or sulphation process are alkylbenzenes having from 9 to 20 carbon atoms in the alkyl group, fatty alcohols containing from 9 to 20 carbon atoms, ethylene oxide condensation products in which from one to ten mols. of ethylene oxide are condensed with one mol. of any of the following: alkyl phenols having 8-20 carbon atoms in the alkyl group, fatty alcohols having 9-20 carbon atoms, fatty acids having 9-20 carbon atoms, fatty acid alkanolamides having 9-20 carbon atoms in the fatty acid residue and 2-4 carbon atoms in the alkanol group. An example is given of the sulphonation of an alkyl benzene derived from alkylating benzene with a propylene tetramer. Specification 680,613 also is referred to.
