Patent GB-1110396-A (GB)
Title: Process for the production of alcohols by oxidation of hydrocarbons
IPC: C07C29/52
Filed: 1965-08-23
Abstract: Alcohols are prepared by the liquid phase oxidation of saturated aliphatic hydrocarbons having at least 10 carbon atoms or cycloaliphatic hydrocarbons having at least 6 carbon atoms with a molecular oxygen-containing gas at an elevated temperature and aqueous boric acid is continuously mixed, at a rate equivalent to the formation of the alcohol, with the hydrocarbon during the whole of the oxidation period and the water added and formed during esterification; the borate ester is subsequently hydrolysed to give the alcohol.  The boric acid is preferably added as a hot saturated solution or as moist boric acid crystals. It is preferred to operate at 130-190 DEG  C.  Examples describe the preparation of cyclodecanol and n-tetradecanol; some ketone corresponding to the alcohol is also formed.

A sleeve 9 is non-rotatably but axially slidable in a housing 1, the axial movement being effected by an hydraulic drive from a piston-rod 27 to a support plate 26 on the sleeve or by a hand drive from a lever 7 connected by a rod 8 to the support plate. The spindle 5 is axially fixed but rotatable in the sleeve by a toothed belt transmission 3 and shaft 2 from a motor 6. The lower end of the spindle 5 has a slide 12 which has a roller engaging a wedge member 11 and houses a further slide 14 adjustable by a spindle 13 and carrying a grinding motor. The wedge member is slidable in the spindle 5 and connected to a sleeve 10 which engages one arm of the angle lever 24. A bar 17 carries the pivot for the angle lever 24, the bar being vertically movable by a spindle 16 rotatably mounted in a hollow shaft 25 rotatable by a shaft 15. The other arm of the lever engages the cam 23, the inclination of which is varied by movement of a slide 20 having a spindle 19 connected through a shaft 18 to a hand wheel. The slide 20 is movable on a slide 22 movable in the housing by a spindle 21 and hand wheel. In operation, the sleeve 9 is adjusted either by the hydraulic drive 27 or manually by the lever 8, and the slide 14 is coarsely adjusted by the spindle 13. The spindle 5 is driven by the motor 6 and the wedge member 11 is movable to effect infeed or transverse movement to the grinding wheel by movement of the sleeve 10. The infeed is effected by rotation of the shaft 15 and worm gear to the shaft 25 and spindle 16 to displace the bar 17 and hence the angle lever 24 and sleeve 10. The slide 22 is movable by the spindle 21 to within a working range, a roller on slide 20 engaging cam 23. Displacement of sleeve 9 rotates the lever 24 as a function of the inclination of cam 23 to control the movement of sleeve 10 and the wedge member 11.

Abstract: 523,231. Coated fabrics. BRITISH CELANESE, Ltd. Dec. 29, 1938, No. 37722. Convention date, Dec. 30, 1937. Drawings to Specification. [Class 140] [Also in IV] Materials such as woven, knitted, or netted fabrics, paper, cardboard, pulp, leather, blocks or sheets of cork, rubber, wood, or asbestos, metal sheets, strips, cloth, or netting, lead pencils, insulated wire, ribbons, mouldings, rods, strips, tubes and corset stays are coated with a composition obtained by kneading a thermoplastic cellulose derivative, a plasticiser, and a non- solvent assisting liquid, firstly at a temperature such that no substantial loss of non-solvent occurs, allowing the mass to stand until a gel is formed, and then kneading the gel at a temperature such that a substantial amount of the non-solvent evaporates while leaving the composition still tacky. The tacky composition is worked on rollers at a temperature above the boiling point of the assisting liquid and is then applied while still tacky to the base material under heat and pressure. The cellulose derivative may be cellulose acetate, benzyl cellulose or other cellulose ester or ether. The assisting liquid may be alcohol, hot water, or a mixture of acetone and water. Plasticisers which may be used include camphor, dimethoxyethyl phthalate, triacetin, triphenyl phosphate, ana ethyl ortho toluene sulphonamide. The composition may contain lead oleate, oils such as the formal of castor oil, blown castor oil, oxidised olive oil, acetylated polymerised castor oil, rapeseed oil, perilla oil, Russian mineral oil, olive oil, dyes, pigments, lakes, fillers, or resins. Foils, films, or sheets of the coating composition may be formed and these may then be applied continuously to the surfaces to be coated. The surfaces may be heated before application of the composition. Subsequently to the coating operation the uncoated portions or underside of the articles may be cooled or chilled. Cellulose ester coatings may be subjected to saponification e.g. with ammonia or caustic soda. Embossing may precede saponification and the saponified product may be treated with a softening agent such as glycerine or diethylene glycol. Examples describe the preparation of cellulose acetate compositions and their application to sateen and cotton drill cloth. The Specification as open to inspection under Sect. 91 comprises also the preparation of coating compositions other than cellulose derivative compositions and is not restricted to a two stage kneading operation. This subjectmatter does not appear dn the Specification as accepted.
