Patent GB-651144-A (GB)
Title: A process for the preparation of oxygenous organic compounds
IPC: C07C27/22
Filed: 1948-04-14
Abstract: In a process for the production of oxygenous compounds comprising aldehydes and alcohols from hydrocarbons with less than 12 carbon atoms containing at least one double bond by treatment with a carbon monoxide- and hydrogen-containing gas in the presence of a suspended hydroformylation catalyst, the catalyst is transported to the reaction space in the form of a suspension which consists at least partly of an oil which is more viscous than any olefinic hydrocarbon with less than 12 carbon atoms.  By this means pumps are not subjected to so much wear and tear. Advantageously the suspension is prepared using substances obtained in the process itself which boil above the range of the desired products.  The use of a concentrated paste is also an advantage.  Thus a suspension of 10-30 per cent or up to 50 per cent by weight of solid catalyst in the said substances is easily pumpable and when the alkene reactant is also present amounts up to 3 per cent by weight of the latter in the finely-prepared paste may be used.

Abstract: 658,897. Retreading tyres. RAWLS, V. April 20, 1949, No. 10495. [Class 144 (ii)] Worn tread lugs 2 of rubber tyres are rebuilt by forming each lug with a uniform convex outer edge surface a to receive a bar 5 of rubber or the like which has its innei surface d concave and coated with adhesive material and is applied under pressure to the adhesive-coated outer edge surface of the tread lug so that initial adhesion of the surfaces occurs only along a central longitudinal section thereof, the adhesion of the side sections being caused subsequently and the 'tyre then cured. As shown, the tread bar 5 has its inner surface d formed concave of smaller radius than the lug 2 so that when applied to the lug 2 contact will occur only along the edges. The bar surface d is first coated with adhesive material and then covered with a strip 7 of non-adhesive glazed cloth the centre portion 8 of which is subsequently torn off to leave side strips 9. The corners of the strips 9 are turned outwardly to form flaps 10 so that when the bar is pressed on to the lug 2 to adhere thereto along its central portion, the strips 9 can be removed to complete the adhesion of the surfaces a, d by pulling the flaps 10, the strips turning outwardly over themselves during removal. The tyre may be cured by the application of steam pressure thereto in a closed chamber.

Title: Process for the production of ketones and aldehydes
IPC: C07C45/74
Filed: 1946-04-15
Abstract: As catalysts in the vapour-phase condensation of ketones and aldehydes with themselves or with one another in the presence of hydrogen, use is made of mixtures containing an oxide of an element of Group II and an oxide of an element of Group V of the periodic system.  Specified catalysts comprise (a) zinc oxide and bismuth trioxide, (b) magnesium oxide and vanadium pentoxide, (c) barium oxide and bismuth trioxide and (d) magnesium oxide and bismuth trioxide deposited in each case on steel turnings.  Other specified carriers for the catalysts are diatomaceous earth, bentonite and talc.ALSO:The condensation of a ketone with itself or with another ketone or with an aldehyde is effected by bringing the vaporized starting material together with hydrogen into contact with a catalyst comprising an oxide of an element of Group II and an oxide of an element of Group V of the periodic system.  The products are generally unsaturated ketones, but saturated ketones may also be formed when the starting material contains five or more carbon atoms. The condensation of an aldehyde with itself or with another aldehyde is effected in the same way, the products in this case being unsaturated aldehydes.  The reaction may be effected at 200-600 DEG C., preferably at 350-450 DEG  C., and at atmospheric or raised pressure.  In the examples: (1) vaporized methyl ethyl ketone and hydrogen are passed over a heated catalyst prepared by depositing a mixture of zinc oxide and bismuth trioxide on steel turnings; the products include methylheptenones and some secondary butyl alcohol; (2) vaporized acetone and hydrogen are passed over a heated catalyst comprising magnesium oxide and vanadium pentoxide or (example 3) barium oxide and bismuth trioxide or (example 4) magnesium oxide and bismuth trioxide on steel turnings; mesityl oxide is recovered in each case from the product; (5)-(7) acetaldehyde vapour and hydrogen are passed over the catalysts of examples (1), (2) and (4), to yield products containing crotonaldehyde; (8) a vaporized mixture of acetaldehyde and acetone is passed with hydrogen over the catalyst of example (1) to yield a product containing pentene-2-one-4; (9) a vaporized mixture of acetaldehyde and methyl ethyl ketone is passed with hydrogen over the catalyst of example (4) or (example 10) the catalyst of example (2) to yield products containing hexene-2-one-4. Reference is made also to the treatment of methyl-n-propyl ketone, methyl isopropyl ketone, methyl - n - butyl ketone, methyl isobutyl ketone, propionaldehyde, butyraldehyde, alicyclic ketones such as cyclopentanone and cyclohexanone, and ketones and aldehydes containing aryl, alkaryl or aralkyl groups.  The reduction of the products to saturated ketones or aldehydes or to secondary or primary alcohols is mentioned.  Other carriers on which the catalysts may be deposited are diatomaceous earth, bentonite and talc.
