Title: Improvements in sulphonation
IPC: H02J7/14
Filed: 1937-07-17
Abstract: Aliphatic substances containing an alcoholic <PICT:0499373/IV/1> hydroxyl group are sulphonated by bringing together continuously flowing streams of the aliphatic substance and the sulphonating agent in the full proportions required for the reaction, allowing the reaction to proceed without restraining the resulting rise in temperature and arresting the reaction by neutralization or rapid cooling or both to prevent side reactions.  In a modification, when the reaction is normally instantaneous, the sulphonating agent is dilluted or the reaction is restrained by slight cooling.  Coconut oil alcohols from storage tank 1 meet a stream of sulphuric acid in a mixer 9.  The reaction is completed in a reaction coil 18 and the product is neutralized by means of caustic soda solution drawn from tank 28, in one of the tanks 20 which are provided with jackets. Local overheating during neutralization may be avoided by diluting the unneutralized product with already neutralized material.  The product is produced in paste form, but a dry product may be obtained by using a modified neutralization chamber in which the sulphonated alcohols and neutralizing solution are brought together in the form of sprays in a splash funnel at the top of a vertical tank maintained at reduced atmospheric pressure.  The sulphonation of secondary alcohols obtained by the oxidation of paraffin and of low molecular alcohols is mentioned.  Alcohols obtained from vegetable and animal fats, fatty oils and waxes, e.g. tallow, sperm oil and corozonut oil and castor oil are further specified starting materials.  Diluents such as nitrobenzene, low boiling hydrocarbons, trichlorethylene, ethylenedichloride and carbon tetrachloride may be used in the sulphonation.  The products are stated to be wetting, sudsing and detergent agents.  The Specification as open to inspection under Sect. 91 comprises also the continuous sulphonation of any sulphonatable organic material such as unsaturated aliphatic hydrocarbons, fatty acids, ketones, ethers and corresponding aromatic, hydroaromatic and aliphatic-aromatic compounds.  This subject-matter does not appear in the Specification as accepted.
