Patent GB-374866-A (GB)
Title: Improvements in or relating to the manufacture of wetting, cleaning, emulsifying, dye-dissolving and water-softening agents
Filed: 1931-02-12
Abstract: Products, stated to be emulsifying agents, are obtained by the simultaneous condensation and sulphonation of fats, fatty oils, fatty acids derived therefrom or esters or anhydrides of the latter with aromatic or hydroaromatic polynuclear hydrocarbons, aralkylhalogenides or unsubstituted alkyl, aralkyl or hydroaromatic alcohols being added during the condensation or afterwards.  In examples (1) tetrahydronaphthalene, castor oil, n-butyl alcohol and benzylchloride are condensed and sulphonated with sulphuric monohydrate; (2) tetrahydronaphthalene, castor oil and cyclohexanol are condensed and sulphonated with chlorsulphonic acid; (3) tetrahydronaphthalene, oleic acid and iso amylalcohol are condensed and sulphonated with oleum, and benzylchloride then condensed with the product by means of a further quantity of oleum; (4) tetrahydronaphthalene, castor oil and iso amyl alcohol are condensed with sulphuric acid monohydrate and the reaction completed with oleum; (5) a mixture of oleum and chlorsulphonic acid is used to condense and sulphonate a mixture of tetrahydronaphthalene, castor oil, n-butylalcohol, benzylchloride and naphthalene.  The following components are also mentioned: anthracene, phenanthrene and their homologues.  The products may be neutralized with ammonia or potassium or sodium hydroxide or with cyclic or acyclic organic bases, e.g. pyridine, quinoline, tetramethylammonium hydroxide, and mono di or tri ethanolamine.  The Specification as open to inspection under Sect. 9 (3) (a) comprises also the use of hexaline (a Registered Trade Mark) and methylhexaline as starting materials. This subject-matter does not appear in the Specification as accepted.ALSO:Products, stated to be wetting, emulsifying dye dissolving, cleaning, and water-softening agents, are obtained by the simultaneous condensation and sulphonation of fats, fatty oils, fatty acids derived therefrom or esters or anhydrides of the latter with aromatic or hydroaromatic polynuclear hydrocarbons, aralkylhalogenides or unsubstituted alkyl, aralkyl or hydroaromatic alcohols being added during the condensation or afterwards.
