Title: Improvements in the manufacture and production of valuable water-soluble condensation products suitable as assistants in the textile and related industries
Filed: 1934-06-15
Abstract: Products stated to be useful in the textile, leather, paper, lacquer, cosmetic, pharmaceutical and rubber industries as wetting, washing, dispersing, levelling and softening agents are obtained by treating aliphatic compounds containing one carboxylic group with (a) at least two molecular proportions of dihydric alcohols free from ether linkages and containing at least three carbon atoms or their corresponding alkylene oxides and (b) polyhydric alcohols containing from 2--4 carbon atoms having one hydroxyl 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 them with further amounts of the said polyhydric alcohols or with polybasic oxygen containing mineral acids.  In a modification, when the starting materials contain at least six carbon atoms, they may be treated first with at least two molecular proportions of the said dihydric alcohols or alkylene oxides and then with sulphonating agents.  In an example, stearic acid is treated successively with three molecular proportions each of ethylene oxide, propylene oxide, and ethyleneoxide.  The product may be used for softening and finishing viscose artificial silk. Propionic, valeric, caproic, lauric, palmitic, ricinoleic and oleic acids and palm kernel, coconut, castor, soya bean and train oils and tallow are mentioned as starting materials which may contain halogen or nitro or sulpho groups.  The products may be used in association with soaps, turkey red oils, alkylated aromatic sulphonic acids, organic solvents, cyclohexanol, cyclohexanone, benzyl alcohol, carbontetrachloride, Glauber's salt, alkali phosphates, water glass, borates, sodium hypochlorite, sodium hydrosulphite, mucilages, glue, starch and ethylene oxide polymerization products.  According to the Provisional Specification organic compounds containing one or more carboxylic groups may be used as starting materials, benzoic, salicylic and naphthoic acids being specified.  The carboxylic acids may be treated with alkylene oxides containing three or more carbon atoms or with compounds capable of acting in the same manner e.g., glycide.ALSO:Products stated to be useful in the textile, leather, paper, lacquer, cosmetic, pharmaceutical and rubber industries as dispersing agents are obtained by treating aliphatic compounds containing one carboxylic group with (a) at least two molecular proportions of dihydric alcohols free from ether linkages and containing at least three carbon atoms or their corresponding alkylene oxides and (b) polyhydric alcohols containing from 2--4 carbon atoms having one hydroxyl group attached to each carbon atom or their corresponding alkylene oxides, in either sequence.
