Abstract

Sulphonic acids of polyalkylated aromatic hydrocarbons and their derivatives are used for dispersing fatty and mineral oils, waxes, hydrocarbons and water-insoluble materials. They are more efficient than the mono- and di-alkylated derivatives. Reference has been directed by the Comptroller to Specifications 244,645, 246,817, 252,392, 261,707, 264,860, 271,543, and 317,355, [all in Class 2 (iii), Dyes &c.].ALSO:Alkylated aromatic hydrocarbons and their derivatives are made by condensing aromatic hydrocarbons or their derivatives, e.g. halogen, hydroxy or amino compounds or sulphonic acids thereof with aliphatic alcohols or mixtures thereof or their esters (2,2 to 4 mols.) and sulphonating if necessary. When higher alcohols are used solvents may advantageously be employed. The hydrocarbon may be first sulphonated and then alkylated or the alkylated hydrocarbon may be sulphonated or the alkylation and sulphonation may be carried out simultaneously. Acid chlorides, e.g. phosphorus trichloride, acetyl chloride, &c. with or without phosphorus pentoxide may be used as catalysts with or without solvents. The products are more efficient as wetting agents &c. than the corresponding mono- and dialkylated products. The dispersive capacity in respect of fatty and mineral oil, waxes, hydrocarbons, dyestuffs and like water-insoluble materials is similarly increased. They also show an increased levelling action in wool dyeing. In examples, (1) naphthalene-b -sulphonic acid is treated with isopropyl alcohol and concentrated sulphuric acid to form multipropylated-b -naphthalene sulphonic acid, (2) n-butanol mixed with naphthalene is treated with oleum, (3) n-butanol is treated with chlorsulphonic and then sulphuric acid and naphthalene added at 45-55 DEG C., (4) a mixture of naphthalene, n-butanol and the 15 carbon chain aliphatic alcohol obtained from soya bean oil by catalytic hydrogenation is treated with oleum, (5) a mixture of naphthalene and isobutyl alcohol is treated with oleum, (6) naphthalene is disulphonated and condensed with n-butanol in sulphuric acid; the alkali salts are suitable as wetting agents for precipitation baths in the artificial silk industry, (7) tri-isopropyl-benzene (from isopropyl alcohol, benzene, and sulphuric acid) is sulphonated, (8) a mixture of diphenyl and n-butanol is sulphonated, (9) tributylphenanthrene sulphonic is made from n-butanol, phenanthrene and sulphuric acid, (10) a mixture of chlorsulphonic acid and n-butanol is condensed with b -chlornaphthalene in sulphuric acid, (11) a mixture of n-butanol and sulphuric acid is added to tetrahydronaphthalene in sulphuric acid and the condensation is completed with addition of oleum. Specifications 224,869, 240,318, 244,645, 246,817, 247,588, 251,294, 261,707, 264,860, 271,543, 277,277, and 317,355, [all in Class 2 (iii), Dyes &c.], are referred to. Reference has been directed by the Comptroller to Specifications 244,645, 246,817, 252,392, 261,707, 264,860, 271,543, and 317,355, [all in Class 2 (iii), Dyes &c.].
