Title: Oxidation of phenols
IPC: C07C50/08
Filed: 1963-06-27
Abstract: Diphenoquinones are produced by reacting oxygen with certain ortho-disubstituted phenols in presence of an oxygen carrier which is a solution of a complex of a primary or secondary amine having no N-aryl bonds and a basic cupric salt.  At least one ortho-substituent may have an aliphatic secondary or tertiary alpha-carbon atom and possibly both ortho-substitutes have this property.  In Example 7, tetra-t-butyldiphenoquinone was obtained from 2,6-di-t-butylphenol with O2, CuCl and (CH3)2NH, in Example 8, tetra-i-propyldiphenoquinone was similarly obtained from 2,6,di-i-propylphenol.  It is also stated that diphenoquinones are produced from p-unsubstituted phenols wherein both o-substituents are aryl, alkoxy or aryloxy groups.ALSO:Polyphenylene ethers are produced by reacting oxygen with phenols of formula <FORM:0982471/C3/1> using as oxygen carrier a solution of a complex of a primary or secondary amine having no N-aryl bonds and a basic cupric salt. In the formula, #C is H, Cl, Br or I; R is a monovalent hydrocarbon, hydrocarbonoxy, haloaryl or haloaryloxy radical; R1 is the same as R or a halogen atom; R11 is the same as for R1 or H, with the provisos that (a) R, R1 and R11 are each free of a tertiary alpha-carbon atom and (b) X is halogen when R and R1 are each aryl, haloaryl, hydrocarbonoxy or haloaryloxy. The examples describe the production of poly(2,6-dimethyl-1,4-phenylene) ethers of various intrinsic viscosities depending on the reaction conditions.

A product for smoking in the form of a cigarette, cigar or cigarillo which contains no tobacco plant parts, comprises a mixture of from 5 to 95 per cent by weight of a film forming ingredient which is an acid gum having an acid value exceeding 30 mg. of potassium hydroxide per gram of gum, and from 5 to 90 per cent by weight of a mineral ingredient, the balance, if any, consisting of compatible ingredients. The mixture is cast into sheets for subsequent processing, e.g. by shredding to form a cigarette filler. Suitable acid gums include acidic pectins and pectates extracted from tobacco, pectin from citrus fruits alginic acid, polyuronic acids, salts of these acids, synthetic esters of alginic acid, and esters of pectic acids. Preferably the pectinic material is that which is derived from tobacco plant parts after destroying the alkaline earth metal cross-links of the pectins by the known methods of (a) precipitating the alkaline earth as an essentially insoluble compound, (b) sequestering the alkaline earth, or (c) treatment with an acid to form soluble alkaline earth salts and release the insoluble free pectic acid. The mineral ingredient may be a calcium, sodium, potassium or magnesium salt, or a clay. Preferably water-insoluble minerals such as calcium and/or magnesium orthophosphates, pyro phosphates and polyphosphates are used. Precipitated tricalcium phosphate is especially preferred. Optional further ingredients, long lists of some of which are given, include nicotine-donating ingredients or nicotine per se plasticizers, sugars, flavours, and colouring.

Filed: 1926-02-25
Abstract: 273,131. Haddan, A. J. H., (Aktiebolaget Ljungstr÷ms Angturbin). Feb. 25, 1926. Air, supplying; air supply, regulating; baffles; doors.--The capacity or rating of flue boiler furnaces is increased with comparatively small structural alteration by admitting the over fire air in a rotating current by means embodied in a detachable front closing the whole of the furnace opening. In the form shown in Figs. 1 and 2, a pair of pipes 10, mounted in the firedoor and arranged to deliver air over the fire, are slit longitudinally and have their adjacent edges connected, as shown at 14, so that air enters tangentially from the supply 12. The proportion between over and under grate air is adjusted by means of a swinging baffle 18 forming part of the partition dividing the two supplies. In a Howden front, Fig. 4, a chamber surrounding the fire door and having a controllable inlet 27 delivers to an inner chamber 32 having a number of delivery nozzles each fitted with a stationary fan 34. In a third modification, Figs. 6 and 8, delivery tubes 43 are slit longitudinally and bent as shewn along the portions within the hollow front to give the air a tangential entry, the amount of air being regulated by discs 44 displaceable by arms 45 having a common operating handle 54. In the full-on position, the handle 54, Fig. 6, lies in front of the furnace door which thus cannot be opened until the air is partially turned off. Reference has been directed by the Comptroller to Specifications 5276/84, 18172/03, and 149/06.

Abstract: 403,488. Lubricators. REAVELL, W., Ranelagh Works, Ipswich, Suffolk. Sept. 22, 1932, No. 26392. [Class 12 (iii).] A lubricator for supplying lubricant drop-by-drop into the inlet pipe c of a compressor, or other machine, when the machine is running, and which ceases its supply when the machine stops, comprises an oil container a with an outlet passage d. A tube f extends through the passage d so as to form a minute annular passage with the passage d. The tube, which extends above the lubricant level is supported by an annular collar f<1> resting on projections e on the container and is loosely held in place by a pin h. When the machine is idle, leakage of oil through the annular channel is prevented by the capillarity of the oil therein, but when the machine is in operation the drops of lubricant forming at the end of the tube f are carried away to the machine.
