Abstract: Sulphonated products having a reserving action upon animal fibres and also stated to be dispersing and tanning agents are prepared by sulphonating compounds obtained by condensing alkali soluble synthetic resins or resinous substances containing phenolic hydroxy groups with alkylene oxides, alkylene halohydrins or halogenated or hydroxy alkylene oxides.  The following resinous compounds may be used: phenol-aldehyde synthetic resins, prepared if desired in conjunction with urea, thiourea, arylsulphonamides, phenolsulphonic acids or naphthalenesulphonic acids; the condensation products of phenols, alone or in the presence of aldehydes or urea with resin acids or other carboxylic acids or with glyptals; vegetable tanning extracts such as quebracho extract; and resins obtained by reacting phenols with sulphur, sulphurhalides, unsaturated high molecular fatty acids or unsaturated hydrocarbons such as acetylene and butadienes.  The resinous compounds, which may contain carboxyl or sulphonamide groups may be treated with ethylene, propylene or butylene oxide, glycide, mixtures thereof or the corresponding alkylene or epihalogenhydrins.  The sulphonation may be effected in the presence of solvents, acetic acid or phosphoric acid.  The products may be after-treated with formaldehyde.  In examples: (1) caustic soda lye is stirred into a melted resin prepared from phenol or cresol and formaldehyde, and ethyleneoxide is introduced; sulphonation is effected with sulphuric acid of various products obtained with different quantities of ethylene oxide; (2) a product prepared according to example 1 is after treated with formaldehyde; (3) an alkali soluble resin prepared from phenol and formaldehyde in the presence of sulphuric acid and urea is treated with ethylene oxide and then sulphonated; (4) resins obtained from colophony and cresol after treatment with various quantities of ethylene oxide are sulphonated; the products coagulate glue and disperse calcium soaps.ALSO:Sulphonated products stated to be dispersing agents are prepared by sulphonating compounds obtained by condensing alkali soluble synthetic resins or resinous substances containing phenolic hydroxy groups with alkylene oxides, alkylene halohydrins or halogenated or hydroxy alkylene oxides.
