Title: Improvements in and relating to the oxidation of hydrocarbons
Inventor: JUBB ANTHONY HOWDEN
Filed: 1962-06-28
Abstract: Aliphatic hydrocarbons are oxidized to a product which includes alcohols by contacting at elevated temperature with an oxygen-containing gas in the presence of a boron compound which is an ester or is capable of forming an ester with an alcohol under the reaction conditions, the quantity of the boron compound being substantially less than the stoichiometric equivalent of the hydrocarbon oxidized.  The aliphatic hydrocarbon is a straight chain or branched chain paraffin, a cycloparaffin or an internal or terminal olefine.  Suitable boron compounds include boric oxide, ortho- and meta-boric acids, alkyl boric acids such as R2BOH and RB(OH)2, the salts of such acids and their esters with alcohols which may be the alcohols formed during the oxidation.  The amount of boron compound used with hydrocarbons containing less than 15 carbon atoms is preferably not more than 0.01 mole/mole of hydrocarbon feedstock. The process may be carried out in the presence of a small amount of a compound of a transition metal, e.g. cobalt, nickel, manganese, vanadium, rhodium or ruthenium.  The products include primary and secondary alcohols and aldehydes or ketones. In the examples, cyclohexane is oxidized to give mainly cyclohexanol and cyclohexanone.

Title: Spiro heterocyclic dithiophosphoric acids and the production thereof
IPC: C07F9/6571
Filed: 1955-08-31
Abstract: The invention comprises spiro heterocyclic dithiophosphoric acids having the formula <FORM:0788954/IV (b)/1> wherein R1, R2, R3, R4, R5, R6, R7, and R8, respectively, designates a hydrogen or halogen atom, or an alkyl or aryl radical; and each X designates a hydrogen atom or the two X's collectively represent a second bond between the adjacent carbon atoms.  The compounds may be prepared by reacting phosphorus pentasulphide with a cyclohexane-1,1-dimethanol or a 3 - cyclohexene - 1,1 - dimethanol, preferably at 10 DEG  to 125 DEG  C. in the presence of an inert solvent such as benzene, toluene, the xylenes, ethylene dichloride, heptane, hexane, ethyl ether or butyl ether.  At temperatures near 70 DEG  C., a reaction time of 6 to 6.5 hours is sufficient to complete the reaction whereupon evolution of hydrogen sulphide ceases and the mixture becomes homogeneous. The reaction mixture is then filtered and the filtrate is stripped by vacuum distillation.  The product may be purified by recrystallization from a solvent such as ethyl ether, or by reacting with aqueous alkali metal hydroxide in an inert water-immiscible diluent such as ethyl ether to form the alkali metal salt, allowing the mixture to stratify into layers, and acidifying the aqueous layer with a mineral acid such as hydrochloric or sulphuric acid.  The 1,3-diol starting materials may be obtained by Diels-Alder condensation of a conjugated diene and an a ,b -unsaturated aldehyde, followed by reaction with formaldehyde in the presence of an alkali metal hydroxide.  This reaction of equimolar parts of butadiene and acrolein yields 3 - cyclohexene - 1 - carboxaldehyde which reacts with formaldehyde and aqueous caustic soda in a 1 : 2 : 1 molar ratio to give 3-cyclohexene - 1,1 - dimethanol.  Catalytic hydrogenation of the latter gives cyclohexane-1,1-dimethanol.  By similar methods, 6-methyl-, 2-phenyl-, 4-chloro-, 2,4,6-trimethyl-, 4,6-dimethyl-, and 4-chloro-6-methyl-derivatives of 3-cyclohexene-1,1-dimethanol may be produced.  Detailed examples are given of the preparation of (1) spiro[(2-mercapto-2-thiono-1,3,2-dioxaphosphorinane) - 5,41 - cyclohexene]; (2) spiro-[(2 - mercapto - 2 - thiono 1,3,2 - dioxaphosphorinane)-5,11-cyclohexane]; (3) the 11,31,51-trimethyl derivative of (1); (4) the 51-methyl derivative of (1); and (5) the 11-chloro derivative of (1).  Other products specified are: the 31-phenyl derivative of (1); the 31-methyl-31-phenyl derivative of (1); the 21-chloro-51-methyl-derivative of (1); the 31,61-diphenyl-51-methyl derivative of (1); and the 21-phenyl derivative of (2).  A list of other suitable 1,3-diols is also given. The novel products are useful as biologically active compounds and as intermediates.

In one form, Fig. 1, the scrap material is initially formed into chips 3 in a machine 2, the chips are cleaned at 10, optionally fed into a cage 13, and introduced into the extrusion housing 15. Before extrusion starts, the housing is subject to a vacuum by connecting an aperture 25 in the housing to a vacuum tank and pump 27 and 28. The chips are then compacted by the extrusion ram 16. A plate 17, which seals the housing during evacuation, is removed to allow extrusion through a die 21. The chips are heated to 400-500‹ C. before introduction into the housing or by a heater 20 surrounding the housing. In an alternative form, Fig. 2, the die 30 is initially moved outwardly of the housing to uncover an evacuation orifice 35. After the air has been evacuated, the die is moved back into the housing, and extrusion of the chips begins. A series of small orifices may alternatively be provided adjacent the die, with the orifices remaining uncovered during extrusion but being small enough not to be blocked. In further embodiments, an orifice may be provided in the movable ram, or in a slide which is laterally movable to align either the orifice or a die with the end of the housing. The extruded structural profiles may be cooled, anodized, and painted, and then baked to produce age hardening.
