IPC: C11D1/72
Filed: 1948-11-05
Abstract: Capillary-active oily polyglycol ether condensation products derived from at least 8 mols. and at most 30 mols, of ethylene oxide and 1 mol. of an organic hydroxy compound selected from the group consisting of fatty alcohols of from 8-18 carbon atoms, aromatic hydroxy compounds containing at least one alkyl radical of at least 4 carbon atoms and alicyclic-aromatic hydroxy compounds are converted into pasty or pulverulent compositions by "mixing" them with at least one-third of their weight of urea, its water-soluble homologues and/or biuret.  The term "mixing" is defined as mixing the components together in their normal form without taking especial steps to render them finely dispersed or atomized and this method is contrasted with that described in Specification 482,367.  The use of an equal weight or more of the urea or other water-soluble component results in a powdery product, lesser amounts yielding waxy soap-like mouldable masses. There may be incorporated also additives normally used in the textile industry such as starch and starch degradation products, e.g. dextrin and British gum, and such inorganic salts as sodium sulphate, sodium phosphate, sodium pyrophosphate, potassium chromate, potassium bichromate and sodium carbonate to provide mixtures for use in cloth printing, dyeing textiles or as cleaning agents.  According to examples: (1) 40 parts of the oily condensate from n-dodecanol and ethylene oxide (8 mols.) are mixed with 60 parts urea yielding a millable powder; a similar product results when 10-30 mols. ethylene oxide are used to form the condensate and when the urea content ranges from 50-99 per cent; (2) 30 parts of the oily condensate from tri-isobutyl phenol and ethylene oxide (10 mols.) are mixed with 70 parts urea; (3) 40 parts of the oily condensate from the fatty alcohols derived from coconut oil fatty acids and ethylene oxide (10 mols.) are mixed with 60 parts urea; (4) 20 parts of the oily condensate from octadecyl alcohol and ethylene oxide (20 mols.) are mixed with 80 parts urea yielding a mass millable to a powder, 15 parts of which with 300 parts British gum and an equal amount of water yield a paste for use in cloth printing; if 60 parts of the oily condensate are mixed with 40 parts urea a paste results and a similar paste is obtained with the oily condensate from oleyl alcohol and ethylene oxide (20 mols.); (5) 30 parts of the oily condensate from the mixture of n-hexadecanol and n-octadecenol obtained from sperm oil and ethylene oxide (13 mols.) are mixed with 70 parts urea; this urea may be replaced in part by other additives, thus, a powder for use with acid-dyestuffs in wool dyeing results from mixing 30 parts of the oily condensate with 50 parts urea and 10 parts each of Glauber's salt and ammonium sulphate; (6) 30 parts of the oily condensate from diisoamyl phenol and ethylene oxide (10 mols.) are mixed with 70 parts urea; 10 parts of this urea may be replaced by sodium carbonate forming a powder which on mixing with 25 per cent potassium bichromate may be used with chrome dyestuffs in wool-dyeing; (7) 30 parts of the oily condensate from iso-octyl phenol and ethylene oxide (10 mols.) are mixed with 70 parts urea; the product ground to a powder may be mixed with sodium pyrophosphate alone or together with sodium carbonate or 20 parts of the urea may be replaced by sodium pyrophosphate, to yield a cleaning agent; (8) 30 parts of the oily condensate from cyclohexyl phenol, cyclohexyl-o-cresol or technical cyclohexyl cresols and ethylene oxide (10 mols.) are mixed with 70 parts ethylene oxide; (9) 40 parts of the oily condensate from oleyl alcohol or n-octadecyl alcohol and ethylene oxide (20 mols.) are mixed with 60 parts biuret yielding a millable mass suitable for use as a levelling agent in wool-dyeing. The Specification as open to inspection under Sect. 91 is not limited to the above-mentioned minimum proportion of water-soluble component, the latter being defined as any water-soluble amide of carbonic acid, and includes the treatment of the polyglycol ethers of higher aliphatic hydroxy compounds in general.  This subject-matter does not appear in the Specification as accepted.ALSO:Capillary-active oily polyglycol ether condensation products derived from at least 8 mols. and at most 30 mols. of ethylene oxide and 1 mol. of an organic hydroxy compound selected from the group consisting of fatty alcohols of from 8 to 18 carbon atoms, aromatic hydroxy compounds containing at least one alkyl radical of at least 4 carbon atoms and alicyclic-aromatic hydroxy compounds are converted into pasty or pulverulent form by "mixing" them with at least one-third of their weight of urea, its water-soluble homologues and/or biuret.  The term "mixing" is defined as the mixing together of the components in their normal form without taking especial steps to render them finely dispersed or atomized and this method is contrasted with that described in Specification 482,367.  The use of an equal weight or more of the urea or other like water-soluble component yields a powdery product; lesser amounts yield a waxy soap-like mass. There may also be incorporated the usual textile additives to form mixtures for use in cloth printing, wool dyeing or cleaning agents (see Group IV (c)).  Examples are given of the conversion into waxy pastes or powders by means of urea or biuret, of the oily condensates obtained from ethylene oxide in various amounts and n-dodecanol, octadecyl alcohol, oleyl alcohol, the fatty alcohols derived from coconut fatty acids, the mixture of n-hexadecanol and n-octadecenol obtained from sperm oil, tri-isobutyl phenol, di-isoamyl phenol, isooctyl phenol, cyclohexyl-phenol, cyclohexyl o-cresol or technical cyclohexyl-cresol respectively.  The Specification as open to inspection under Sect. 91, is not limited to the above minimum amounts of the water-soluble component, the latter being defined as any water-soluble amide of carbonic acid, and includes the treatment of the polyglycol ethers of higher aliphatic hydroxy compounds in general.

The term "mixing" is given the meaning of mixing together the components in their normal form without taking especial steps to render them finely dispersed or atomized and this method is contrasted with that referred to in Specification 482,367.  The use of an equal weight or more of the urea and the like water-soluble additive results in a powdery product while lesser amounts yield waxy soap-like mouldable masses.  There may be incorporated in the products further usual additives such as starch and starch degradation products like dextrin and British gum, and such inorganic salts as sodium sulphate, sodium phosphate, sodium pyrophosphate potassium chromate, potassium bichromate and sodium carbonate to provide mixtures for use as cleaning agents, in cloth printing or in dyeing textiles.  According to examples: (1) 40 parts of the oily condensation product from 1 mol. n-dodecanol and 8 mols ethylene oxide are mixed with 60 parts of urea yielding a millable powder; a similar powder is obtained when 10-30 mols ethylene oxide are used to form the oily condensate and when the urea content ranges from 50-99 per cent; (2) 30 parts of the oily condensation product from ethylene oxide (10 mols) and triisobutyl phenol (1 mol.) are mixed with 70 parts urea giving a solid, millable to a powder; (3) 40 parts of the oily condensation product from ethylene oxide (10 mols) and the fatty alcohols (1 mol.) derived from coconut oil fatty acids are mixed with 60 parts urea giving a product millable to a powder; (4) 20 parts of the oily condensation from ethylene oxide (20 mols) and n-octadecyl alcohol (1 mol.) are mixed with 80 parts urea giving a mass millable to a powder; 15 parts of the powder are mixed with 300 parts British gum and worked up with an equal amount of water to form a paste for use in cloth printing; if 60 parts of the oily condensate are mixed with 40 parts urea a mouldable waxy paste results and a similar paste is obtained using as the oily condensate, one derived from ethylene oxide (20 mols) and oleyl alcohol (1 mol.); (5) 30 parts of the oily condensation product from ethylene oxide (13 mols) and the technical mixture of n-hexadecanol and n-octadecenol obtainable from sperm oil are mixed with 70 parts urea giving a solid millable to a powder; this urea may be replaced in part by other additives, e.g. water-soluble alkali salts, thus a powder for use in conjunction with acid dyestuffs in wool dyeing results from mixing 30 parts of the said condensation product with 50 parts urea and 10 parts each of Glauber's salt and ammonium sulphate; (6) 30 parts of the oily condensation product from ethylene oxide (10 mols) and diisoamyl phenol (1 mol.) and 70 parts urea give a mass millable to a powder; 10 parts of this urea may be replaced by sodium carbonate forming a powder which on mixing with 25 per cent potassium dichromate may be used with chrome-dyestuffs in wool-dyeing; (7) 30 parts of the oily condensation product from ethylene oxide (10 mols) and iso-octylphenol (1 mol.) are mixed with 70 parts urea and the product ground to a powder; this powder may be mixed with sodium pyrophosphate alone or together with sodium carbonate or 20 parts of the above urea may
