Patent GB-475955-A (GB)
Title: Surface-active compounds and their manufacture
Filed: 1936-02-24
Abstract: Products stated to have wetting, foaming, dispersing, and detergent properties are prepared by condensing a sulphonated p  diaryloxide having the formula C6H5OAr in which Ar stands for phenyl or naphthyl containing no chromophor substituent, with the sulphuric ester of an aliphatic alcohol containing more than two carbon atoms or of a hydroaromatic alcohol.  From one to five alkyl or hydro-aromatic radicles are thus introduced into the diaryloxide nucleus.  In modifications, the sulphuric esters of the alcohols may be obtained from the corresponding olefines, and the sulphonation may be effected during or after the condensation of the diaryloxides and alcohols. In examples: (1) diphenyloxide is sulphonated and condensed with the sulphuric esters of iso-propyl alcohol, sec: butylalcohol, sec: butylcarbinol, methyl-n-propylcarbinol, diethylcarbinol, cyclohexanol and a methyl-cyclohexanol isomeric mixture; (2) diphenyloxide is treated with chlorsulphonic or sulphuric acid and butylalcohol, methyl-n-propylcarbinol, n-amyl-alcohol, n-heptylalcohol, borneol, cyclohexanol, fenchylalcohol, dipentene, terpineol, terpinolene, pinene, a mixture of olefines obtained by a cracking process or a mixture of branched chain alcohols obtained by a methanol synthesis; (3) a mixture of hexahydroquinone, diphenyloxide and tetrachlorethane is treated with sulphuric acid; (4) phenyl-a -naphthyloxide is sulphonated and condensed with isopropyloxide; (5) p-phenoxydiphenyloxide is sulphonated and condensed with isopropyl-alcohol.  The products may be used for treating textiles, leather or paper, the removal of spray residues from fruits and for de-emulsifying petroleum-water emulsions.  They may be employed in disinfecting and antiseptic mixtures, in the froth flotation of ores, in insecticidal sprays and as dispersing-agents in the dyestuff industry.ALSO:Products stated to have emulsifying and dispersing properties are prepared by condensing a sulphonated diaryloxide having the formula C6H5OAr in which Ar stands for phenyl or naphthyl containing no chromophor substituent, with the sulphuric ester of an aliphatic alcohol containing more than two carbon atoms or of a hydroaromatic alcohol.
