Patent GB-781454-A (GB)
Title: Improvements in or relating to the production of aralkyl carboxylic acids and amidesand thioamides thereof
IPC: C07C45/36
Filed: 1953-07-02
Abstract: Aralkyl carboxylic acid amides or thioamides (which may be subsequently hydrolysed to aralkyl carboxylic acids) are prepared by oxidizing an aromatic hydrocarbon of formula A-CH(R1)R2, wherein A is a phenyl, tolyl or xylyl group, the -CH(R1)R2 group is attached directly to the aromatic nucleus, R1 is hydrogen, methyl or ethyl and R2 is methyl, ethyl or propyl, in the liquid phase in the presence of an oxidation catalyst and at a temperature below 180 DEG  C. by means of a gas containing or consisting of molecular oxygen, whereby an aryl alkyl ketone is formed, distilling the oxidation product with recovery of a fraction consisting predominantly but not entirely of said ketone, and thereafter reacting said fraction with a Willgerodt reagent as hereinafter defined.  The Willgerodt reagent is defined as ammonium polysulphide, a mixture of sulphur and ammonia, or a mixture of sulphur with a primary or secondary amine.  The preferred hydrocarbons are those wherein R1 is a methyl group, giving an acetyl substituted compound on oxidation. The oxidation is preferably carried out with air, at a pressure of 1-10 atmospheres, and with intimate mixing.  Specified oxidation catalysts are compounds of manganese or cobalt such as cobalt stearate or isononanoate or naphthenate.  The crude oxidation product usually separates into an upper organic phase and a lower aqueous phase, the ketone being removed by distillation.  The crude oxidate upon distillation gives unreacted hydrocarbon, a ketone containing fraction and a high-boiling residue.  Any acids formed in the oxidation may be removed by alkaline extraction. When a hydrocarbon of the general formula wherein R1 is methyl and R2 is methyl, ethyl or propyl is oxidized and the oxidate distilled, a fraction coming after the ketone fraction is obtained comprising a mixture of the ketone and a phenyl dialkyl carbinol.  This fraction is dehydrated to convert the carbinol to an olefin, the dehydrated mixture being recycled to the oxidation stage.  The ketone containing fraction is then heated with the Willgerodt reagent; acetophenone for example, giving with sulphur and aqueous ammonia or ammonium polysulphide phenylacetamide and a little phenylacetic acid, and with sulphur and morpholine the thiomorpholide.  Both products may be hydrolysed to phenylacetic acid.  In examples: (1) sec.-butyl-benzene was oxidized with air using cobalt isononanoate as catalyst, the oxidate distilled and the acetophenone fraction heated in an autoclave with sulphur, ammonia, water and pyridine to give phenylacetamide which was hydrolysed with lime water to phenylacetic acid; (2) the oxidation stage of (1) was repeated with varying conditions.

Filed: 1936-07-07
Abstract: 474,003. Folding aircraft wings. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., SIR W. G., and LLOYD, J. July 7, 1936, No. 18821. [Class 4] In aircraft having wings on opposite sides of the fuselage each wing is divided transversely of its span into at least three sections arranged and hinged to one another in such manner that the outer sections of each wing can be folded to lie horizontally alongside one another adjacent the inner section. A fuselage 11, Fig. 1, is provided with fixed stub sections 12, which may carry engines 27 and alighting gear elements, to the upper outer ends of which intermediate sections 14 are hinged at 13, tip sections 16 being in turn hinged at 15 to the lower outer ends of sections 14. All the hinges are substantially parallel to the longitudinal axis of the machine. At each edge remote from a hinge are arranged locking bolts for front and rear spars. Folding is effected by withdrawing the bolts of section 16 folding this section under section 14 then withdrawing the bolts holding section 14 and folding this section and section 16 over stub section 12. In order to balance the weight of the sections spring means may be provided to act on each hinge-pin 21, Fig. 2. A chain sprocket 22 is formed integrally with the hinge pin and is keyed to the outer spar boom. Sprocket 21 in the case of section 16, is coupled by a chain 23 to a larger sprocket 24a formed with a lever 25a to which a spring 26 is connected. The action of spring 26 is to take the weight of the section during folding or extending, and when arm 25a has moved over the dead centre during folding to maintain the section 16 firmly against section 14. In the case of the sprocket 22 which is keyed to the upper spar boom of section 14, a sprocket 24 of equal size is employed and lever 25 and spring 26 are so disposed that the action of the spring is to relieve the weight of sections 14, 16 both in the upward movement to a vertical position and in the downward movement to the fully folded position. Remote control of the locking and folding gear may be used and in particular the looking pins may be formed as the piston of hydraulic cylinders.
