Title: Improvements in the manufacture and production of valuable water-soluble condensation products suitable as assistants in the textile and related industries
IPC: C08G65/28

Abstract: Products stated to be useful in the textile, leather, paper, lacquer, rubber, cosmetic and pharmaceutical industries as wetting, washing, dispersing, levelling and softening agents are prepared by treating aliphatic compounds containing at least one amino or carboxyamido group with (a) at least two molecular proportions of dihydric alcohols free from ether linkages containing at least three carbon atoms or their corresponding alkylene oxides and (b) polyhydric alcohols containing from 2--4 carbon atoms and one hydroxy group attached to each carbon atom or their corresponding alkylene oxides, in either sequence.  The solubility of the products may be increased, if necessary by treating with oxygen containing polybacic mineral acids or with further amounts of the said polyhydric alcohols.  In a modification, when employing starting materials containing at least eight carbon atoms, the latter are treated with three molecular proportions of the said dihydric alcohols and the condensation product then sulphonated.  In an example, cetylamine is treated first with propylene oxide and then with large excess of ethylene oxide. The product may be used in dyeing wool.  The use of epichlorhydrin and 1 : 2-propyleneglycol, is mentioned and the following starting materials, butylamine, octylamine, oleylamine and lauric acid amide. Halogen atoms and nitro and sulphonic groups may be present in the starting materials.  The products may be used in association with soap, turkey red oil, alkylated aromatic sulphonic acid, organic solvents, cyclohexanol, cyclohexanone, benzyl alcohol, carbon tetrachloride, Glauber's salt, alkali phosphate, waterglass, borates, sodium hypochlorite, sodium hydrosulphite, mucilage, glue, starch and ethyleneoxide polymerization products.  According to the Provisional Specification, organic compounds containing one or more amino groups e.g., aniline, phenylenediamine, benzidine, naphthylamine, aminonaphthols and cyclohexyldiethanolamine or acid amides may be used as starting materials.  Instead of the dihydric alcohols, alkylene oxides containing three or more carbon atoms or compounds capable of acting in the same manner e.g. glycide may be used. Specification 443,559 is referred to.ALSO:Products stated to be useful in the textile, leather, paper, lacquer, rubber, cosmetic and pharmaceutical industries as dispersing agents are prepared by treating aliphatic compounds containing at least one amino or carboxyamido group with (a) at least two molecular proportions of dihydric alcohols free from ether linkages containing at least three carbon atoms or their corresponding alkylene oxides and (b) polyhydric alcohols containing from 2--4 carbon atoms and one hydroxy group attached to each carbon atom or their corresponding alkylene oxides, in either sequence.
