Abstract: Splitting fats; dust-binding agents; lubricants.--Aqueous dispersions of alkyl and cycloalkyl esters of aromatic sulphonic acids are used as emulsifying and dispersing agents, e.g. for fats, sizes and impurities.  The dispersions may also be used, preferably mixed with oils or fatty substances as spinning oils. The esters may be used alone or in association with sulphonated oils, soaps or fat solvents, e.g. hydrocarbons, chlorhydrocarbons, alcohols or ketones.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use, for the same purpose, of esters of aromatic sulphonic acids which are alkylated in the nucleus or are partially hydrogenated.  The esters may also be used for splitting fats and as dust-binding agents and boring oils for metals.  The use of the esters as emulsifying agents in salves, creams and cosmetics and for dispersing powders in general is referred to.  This subject-matter does not appear in the Specification as accepted.ALSO:The wetting, dispersion, penetration and conveyance of effective substances in liquid or plastic preparations used in the textile and leather industries is improved by the addition of aqueous dispersions of alkyl and cycloalkyl esters of aromatic sulphonic acids.  Aromatic sulphonic acids or their salts, sulphonated oils, soaps or fat solvents, e.g. hydrocarbons, chlorhydrocarbons, alcohols or ketones, may also be present.  The esters may be prepared by treating the aromatic sulphonic acids with phosphorus pentachloride and treating the resulting sulphonyl chlorides with the appropriate alcohol.  The dispersions of the esters may be used in foam dyeing and in the treatment of textile fibres with any neutral, acid or alkaline liquid, fats, sizes and impurities, when present being emulsified. Aqueous dispersions of the esters, especially in conjunction with oils or fatty substances may be used as spinning oils.  The dyeing of fur is mentioned.  Specification 312,688, [Class 2 (ii), Cellulose &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of the esters, including esters of aromatic sulphonic acids which are alkylated in the nucleus or are partially hydrogenated, in the manufacture of dust binding agents, compositions for destroying pests, boring oils and corrosives for the metal industry, cosmetics (including salves and creams), and also for dispersing solid substances, e.g. ceramics, dyes and inks, and for splitting fats.  This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 (3) (a) comprises the use of alkyl and cycloalkyl esters of aromatic sulphonic acids, particularly of aromatic sulphonic acids which are alkylated in the nucleus or are partially hydrogenated in the manufacture of corrosives for metals. The esters are melting and dispersing agents.  The esters may be used alone or in association with sulphonated oils, soaps or fat solvents, e.g. hydrocarbons, chlorhydrocarbons, alcohols or ketones.  This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 (3) (a) comprises the use of alkyl and cycloalkyl esters of aromatic sulphonic acids, particularly of aromatic sulphonic acids which are alkylated in the nucleus or are partially hydrogenated, as wetting agents in compositions for destroying pests.  The esters may also be added to salves, creams &c. in the production of cosmetics.  The esters may be used alone or in association with sulphonated oils, soaps or fat solvents, e.g. hydrocarbons, chlorhydrocarbons, alcohols or ketones.
