    Abstract: 1,151,574. Cycloalkanols and cycloalkanones. BADISCHE ANILIN- & SODA FABRIK A.G. 16 Sept., 1966 [17 Sept., 1965], No. 41468/66. Heading C2C. A mixture of a cycloalkanol and a cyclealkanone is obtained from a cycloalkane having 5-12 ring atoms by contacting the cycloalkane with molecular oxygen at a temperature of about 80-200‹ C., a pressure to maintain the reaction mixture in the liquid phase and in the presence of a cycloalkane oxidation catalyst and a minor amount of an olefinically unsaturated compound containing 3-20 carbon atoms which can be epoxidized under the reaction conditions. Suitable cycloalkane oxidation catalysts are, for example, the salts of vanadium, chromium, manganese, molybdenum, iron, cobalt or nickel with lauric acid, oleic acid, palmitic acid, stearic acid and naphthenic acids or the acetylacetonates, acetonylacetonates or carbonyls of these metals. Suitable olefinically unsaturated compounds are unsaturated hydrocarbons or those containing halogen, hydroxyl, carboxyl, ester or ether substituents. Examples are given of the oxidation of cyclohexane and cyclooctane.

    Abstract: A finishing agent for synthetic fibres and fabrics comprises an aqueous solution of an ethenoxylated polyamide which is produced by reacting 1 part by weight of polyamide with 2.5-3.5 parts by weight of ethylene oxide at 80-100 DEG C. and a pressure between 2 atmospheres gauge and the liquifaction pressure of the ethylene oxide and dissolving the product in water at 90-150 DEG C. The polyamide may be produced in the presence of an acid or neutral catalyst from pentamethylene diamine, hexamethylene diamine, and/or decamethylene diamine or salts thereof, adipic, pimelic, sebacic, terephthalic, phenylene diacetic or phenylene dipropionic acids or derivatives thereof having oxygen or sulphur in the carbon chain, o -amino-butyric, caproic, caprylic, capric, undecanic and dodecanic acids or lactams thereof. Their water content may be reduced to less than 1%. Unreacted ethylene oxide may be recovered by restoring atmospheric pressure within the reaction vessel and condensing the issuing gas. The ethenoxylated polyamide may be dissolved in the presence of a solubilizer, or oxidizing or reducing agent. Solubilizers specified are: ethanol, propanol, ethylene glycol, ethylene glycol monomethyl ether, T.H.F., dioxane, acetone, H2SO4, H3PO4, H3BO3, HCOOH, CH3COOH. 20-200% may be used. 0.05-1% H2O2 may be used as oxidizing or reducing agent. Other suitable reducing agents are NaBH4 and sodium hypophosphite. The colloidal solution may contain 1-50% of the ethenoxylated polymer. The water may be allowed to evaporate and the product redissolved in hot water.ALSO:The water-absorbency of fibres, fabrics and sheets may be increased by impregnating them with an aqueous colloidal dispersion of an ethenoxylated polyamide. The solution is prepared by treating a polyamide with 2.5-3.5 times its own weight of ethylene oxide at 80 DEG -100 DEG C. and a pressure between 2 atmospheres and the liquifaction pressure of ethylene oxide and dispersing the reaction product in water at 90 DEG -150 DEG C. Polyamides specified include nylon 6/66 and nylon 6.20-50% of the ethenoxylated polyamide may be dispersed in water in the presence of a solubilizing agent, e.g. EtoH. 0.05-1% of an oxidizing agent, e.g. H2O2, or 0.05-0.5% of a reducing agent may also be present during dispersion. The pH of the dispersion may be adjusted to 3-7, e.g. with acetic acid. The viscous or gelatinous dispersion may be diluted with water before impregnation to 1-10% concentration. The impregnation may be at elevated temperature using a foulard or by steeping and drying.

    Abstract: Antistatic plastics materials are obtained by incorporating 0.5 to 20 wt. per cent of an antiitatic agent which is a reaction product of an alkylene oxide and a polyamide in the melt of 99.5 to 80 wt. per cent of the plastics material. Specified plastics are polystyrene, polyvinyl chloride, polyacrylates, polyethylene, polypropylene, polyformaldehyde, polycarbonates, polyamides and saturated polyesters. The antistatic agent may be obtained by reacting ethylene and/or propylene oxide with various polyamides or copolyamides, e.g. from capro-, capryl- or lauric lactam and/or adipic, suberic or sebacic acid and hexa-, octa- or dodecamethylene diamine, or mixtures thereof which may be cross-linked. In examples: (a) a reaction product of ethylene oxide and a 90/10 mixture of nylons 6 and 66 are melt-blended with (i) an impact polystyrene/rubber mix (70 parts styrene bulk polymer and 30 parts mixture of butadiene-styrene copolymer with emulsion polystyrene and (ii) nylon 6; (b) the same reaction product is kneaded at 190 to 240 DEG C. with polypropylene in the presence of di-t-butyl peroxide and the product melt-blended with polypropylene; (c) using the same peroxide a nylon 6-ethylene oxide reaction product is bulk grafted with polystyrene in the presence of calcium stearate and titanium dioxide and the product melt-blended with polystyrene; and (d) a propylene oxide-polycapryllactam reaction product is melt-blended with acetylated polyformaldehyde. Various articles which may be made from the materials are mentioned.

    Abstract: An organic compound which is liquid under normal conditions and contains an active hydrogen atom is allowed to trickle down a tower packing in a reactor at between 20 DEG and 200 DEG C. and is simultaneously treated with an alkylene oxide and a catalyst at a pressure which is less than the liquifaction pressure of the alkylene oxide at the temperature used. The reactor may be a vertical tube of which the cross-section is less than the height. It may be either conical or telescopic in shape, being narrower at the top than at the bottom. The temperature at the top may be lower than that of the remainder and the pressure may be 6-60 atmospheres. The organic liquid may be introduced at the top of the tower through a distributer plate. Organic liquids specified are: alkanols having 1-30 carbon atoms, phenol, cresols, ethylene glycol, 1.2-propylene glycol, polyalkylene glycols, glycerol, sorbitol, carboxylic acids, and primary and secondary amines. The alkylene oxide may also be introduced at the top of the tower and may be diluted with an inert gas, e.g. N2. Alkylene oxides specified are: ethylene oxide, 1,2-propylene oxide, 1,2-butylene oxide and 2,3-butylene oxide. Catalysts specified are: NaOH, KOH, LiOH, Na2CO3, NaHCO3, oxalic acid, H2SO4, boron trioxide, aluminium oxide and silicic acid gel. The catalyst may form part of the packing. The products may be discharged through a separator at the bottom of the tower or products of differing degrees of oxyalkylation may be withdrawn at different levels of the tower. Oxyalkylation degrees of 1-50 may be achieved. A plurality of reactors may be linked one above the other or side-by-side with the interposition of pumps. In a typical Example (1) tridecanol is treated with ethylene oxide in the presence of NaOH.ALSO:An organic liquid having an active hydrogen atom is run down a tower packing at 20-200 DEG C. and simultaneously treated with an alkylene oxide and a catalyst at a pressure below the liquifaction pressure of the alkylene oxide.
