Abstract: <PICT:0686529/III/1> <PICT:0686529/III/2> <PICT:0686529/III/3> Oils of mineral origin, particularly cracked oils, are desulphurized by subjecting them to the action of hydrogen or ozone, produced in an oscillating magnetic field and to the action of a mixture of hydrogen and oxygen produced by the electrolysis of an acid or alkaline electrolyte.  In Fig. 1, the oil in tank 1 (which oil may contain fractions ranging from gasoline to gas oil or may contain gasoline and kerosene only, and may be produced by high pressure cracking) is passed into an agitator 2 where it is treated with alcoholic caustic soda.  The mixture is stratified in settling tank 4 and the lower layer, comprising alcoholic caustic soda, gummy constituents from the oil and some sulphur compounds from the oil, is freed from alcohol in still 5, the alcohol vapours being passed to condenser 6 and the condensed alcohol being returned to tank 3 for reuse.  The upper layer of oil from tank 4 is passed to tank 7 (see also Fig. 2) which contains an aqueous acid or alkaline solution 8, preferably aqueous caustic soda, the oil forming an upper layer 9.  Within tank 7 are a lead plate electrode 12 and a copper or other metal wire mesh screen electrode 14, the two electrodes being connected by leads 15 to a source of direct current so that electrolytic hydrogen and oxygen is produced in tank 7.  In addition, air or hydrocarbon gas or vapour is introduced through pipe 18 and, after passage through an oscillating magnetic field in tube 17, with resultant conversion to ozonized air or hydrogen respectively, is fed into tank 7 through pipe 16 and perforated spiral pipe 11 (see also Fig. 3). Tube 17 is provided with two wire coils 19, 20, one inside and one out, and one end of each of these coils is connected to a high voltage, high frequency electric oscillator.  Vapours escaping from outlet 10 of tank 7 are passed through a condenser for the recovery of oil, then in turn through caustic soda solution and lime, and finally recycled to tube 17.  Oil layer 9 is drawn off and fractionated.

Abstract: 1,127,005. Crimping yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 July, 1966 [6 Aug., 1965], No. 33733/65. Headings D1F and D1W. A multifilament polyamide, polyester, or a polypropylene yarn is crimped by passage between a driving gear wheel and a driven gear wheel to impart a primary crimp and between the driving gear wheel and a second driven gear wheel to impart a secondary crimp. The secondary crimp has a random, three-dimensional curvilinear configuration of low frequency and high amplitude compared with the primary crimp. The gears wheels which may be of the same or different sizes are preferably disposed in a draw-twister either between the snubbing pin and the draw rolls or instead of the draw rolls. The yarn may be cooled between the two driven gear wheels by an air stream. A variable crimp may be produced by having gaps in the periphery of the gear wheels, or by having the second driven gear wheel slightly eccentrically mounted. Crimp in the yarn may be developed by passing the yarn before wind-up through a steam relaxing tube, or by overfeeding the yarn onto the take-up package, and steaming the package. The yarn may be composed of bi-component filaments.

Patent GB-929916-A (GB)
Title: Process for separation and purification of alkanols
IPC: C07C29/80
Filed: 1961-09-21
Abstract: <PICT:0929916/III/1> A mixture of C2-C24 alkanols containing dissolved water, e.g.a. C2 to C10 mixture, obtained by the hydrolysis of complex aluminium alkoxides, is fractionated in a system essentially comprising two distillation columns 14 and 46 and an intermediary decanter 20.  The mixture of alkanols enters the wash water tower 4 via line 2 and is mixed with a counter-current stream of hot water entering via line 7, using agitator 6.  The hot water removes water-soluble impurities from the mixture of alkanols and leaves the tower via line 8.  The wet mixture of alkanols from the tower is pumped via line 10 and heat exchanger 12 into the column 14, wherein the mixture is resolved into a dry bottoms product rich in heavy alkanols (C4 and above) and an overhead fraction containing substantial quantities of light alkanols (C2-C8) and water.  The overhead fraction condenses in condenser 18 and passes into decanter 20. The water-rich phase 24 is recycled via line 26 into the wash-water feed line 7.  The alkanol-rich phase 22 is pumped via line 42 and heat exchanger 44 into column 46, where it is separated by fractional distillation into an ethanol-water azeotrope, which is withdrawn from the condenser 48, and a C4-C8 alkanol fraction, which is pumped back to column 14 via line 50 to act as a reflux.  The product rich in heavy alkanols drawn from the base of column 14, is pumped via line 28 into the fractionating column 30, where it is fractionated to yield an overhead product of butanol via line 32 and condenser 34, and a bottoms product of dry, heavy alkanols (C6 and above) which may be fractionated further if desired.  Part of the butanol fraction is used as a reflux for column 30 via line 36, and part of it may also be returned to column 14 via line 40, for use as a reflux.ALSO:A complex mixture of alkanols, obtained in the oxidation and hydrolysis of complex aluminium alkyls produced by the reaction of simple aluminium alkyls, such as aluminium triethyl, with an olefin, such as ethylene, are separated and purified from water and accompanying salts by a process of fractional distillation in a system essentially comprising two distillation columns and an intermediary decanter to remove the water (see Group III). Example I gives details of the separation by this process of a mixture of ethanol, butanol, hexanol, octanol, decanol and water.

Title: Process for producing oil-extended polymers
IPC: C08K5/01
Filed: 1966-07-29
Abstract: Oil-extended polymers are prepared by generating free radicals in a solution of a polymer or copolymer in an inert solvent thereby cross-linking the polymer or copolymer and then removing the inert solvent, the polymer or copolymer being formed by solution polymerization of 1,3-butadiene, the copolymer (if present) containing at least 50% by weight of 1,3-butadiene units, and the said inert solvent solution containing 5 to 300 parts by weight of a process oil per 100 parts by weight of the polymer or copolymer.  The preferred copolymer is a butadiene-styrene copolymer.  A Ziegler-type catalyst or a lithium-based catalyst is preferably used in the solution polymerization.  The free radicals may be generated in solution by adding peroxides as free radical generators and heating the solution.  Maleic anhydride, maleic acid or divinylbenzene may be used as cross-linking assistants for the peroxide.  The process-oil may be a paraffinic, naphthenic or aromatic hydrocarbon having a viscosity-gravity constant of 0.79-1.00. Other free radical generators are azo compounds and compounds which generate radicals under ultra-violet light or g -radiation. Inert solvents used in the examples are n-hexane and toluene. Free radicals generators used are benzoyl peroxide, lauroyl peroxide, azobis-isobutyronitrile, diphenyl disulphide as photo-sensitizer irradiated with ultraviolet light, dicumyl peroxide and p-methane hydroperoxide. A butadiene-isoprene copolymer is used in Example 13.  Catalysts used in the preparation of the polymers are n-butyl, sec.-butyl and iso-butyl lithium, 1,2-dilithiostilbene, triethyl aluminium / boron trifluoride / nickel naphthenate, triethyl aluminium / titanium tetrachloride/iodine.  The oil-extended polymers may be cured and compounded using sulphur, N-cyclohexyl-2-benzothiazole sulphenamide, stearic acid, zinc oxide, phenyl-b -naphthylamine, carbon black, an aromatic process oil, dibenzothiazole disulphide, diphenyl guanadine, silicic anhydride and 2,6-ditertiary butyl hydroxytoluene.
