Title: Improvements in processes for reclaiming dyed cellulose nitrate film scrap
IPC: C08J11/06
Filed: 1931-05-22
Abstract: The dyed layer on waste nitrocellulose films is removed by treating the films with an alcoholic solution of an alkali under such conditions as will hydrolyse the surface layer of the film containing the dye.  Caustic alkali is preferably used; and the solution may be prepared by dissolving solid caustic soda in alcohol or aqueous alcohol, or adding a concentrated aqueous caustic soda solution thereto.  Alternatively the solution may be made by dissolving ammonium, sodium or potassium carbonate, tribasic sodium phosphate, or sodium peroxide in aqueous alcohol. The depth to which hydrolysis proceeds, is determined by adjusting the duration of the treatment or the amount of alkali employed. To ensure removal of the hydrolysed layer, the film may be washed as with warm alcohol and water.

Title: A method for sweetening hydrocarbon liquids containing mercaptans
IPC: C10G27/04
Filed: 1947-06-11
Abstract: Hydrocarbon liquids containing mercaptans are sweetened by first saturating with air, and then contacting with an aqueous alkali solution containing an oxidation catalyst, with or without a solubility promoter, i.e. a reagent which increases the solubility of the mercaptans in the solution.  The oxidation catalyst may be a phenolic substance capable of oxidation to the quinone form, specified examples of which are butyl pyrogallol, n-butyro pyrogallol, hydroquinone, anthragallol, gallic acid, tannic acid, and that fraction of hardwood tar boiling between 240 DEG  and 300 DEG C.  The solubility promoter may be an alkali naphthenate, phenolate or isobutyrate.  The hydrocarbon liquids may be saturated with air at atmospheric temperature and pressure; when they contain more than 0.03 per cent mercaptans by weight, either increased pressure may be used, or alternatively the liquids may be pretreated with an alkaline solution containing solubility promoters, to remove the bulk of the mercaptans. Examples are given of the treatment of straight run and cracked gasoline and of Stoddard's solvent.

Title: Improvements in rod-mills used especially for the manufacture of inks and paints
IPC: B02C4/22
Filed: 1962-04-24
Abstract: 1,008,895. Roller-and-bar mills. J. M. A. BRIZON. April 24, 1962 [April 22, 1961 ; July 7, 1961 ; Feb. 27, 1962], No. 15483/62. Heading B2A. A mill for grinding paint or printing ink comprises pressure means 5, 6 for applying a bar 4 against a roller 1, the operative face of the bar having a cavity 9 which is open towards the roller and supplied with fluid under pressure from a pump. The fluid may be the material itself, one of its constituents or a fluid compatible with the material. One or more clamps 5, 6, Fig. 1, are each hydraulically or mechanically operated by an adjustable source to urge the bar 4 against the roller 1 while a pump 10 draws material from a hopper 2 and delivers it to one or more cavities 9 in the bar. Grinding is effected on material which is carried from the hopper on the roller by the action of the pressurized material in the cavity. In the embodiment shown in Fig. 4, an airoperated pump 15, 17 serves to draw material from a separate tank 16 and deliver it to the cavity 9. In operation, the pressure in the cavity becomes stable, such pressure being related to the pressure applied on the clamp. When this pressure is reached the pump stops and normally remains so until all the material in the hopper is ground. A hand or motordriven pump may be employed instead of the air-operated pump for use when starting up the mill. In the embodiment shown in Fig. 5, the bar is arranged vertically and the intake lip 9a has a greater width than the outlet lip 9b, a clearance existing between the lip 9a and roller. When starting up, the roller is rotated a small amount by hand or motor so that the operative faces are primed with material from the hopper. If desired, a plurality of bars 4 may be arranged in contact with a single roller. The invention can also be applied to roller and bar mills comprising a plurality of rollers.

Abstract: Pyrimidines of the formula <FORM:0635582/IV (b)/1> (where X and Y may be hydrogen, halogen, alkyl, amino, or substituted amino, and one, but not both, is halogen; R and R1 are hydrogen or hydrocarbon) or functional derivatives thereof, are prepared by the reaction of a suitable 4- or 6-halogeno-5-nitropyrimidine with an a -aminoaldehyde or ketone of the formula NH2.CHR.CO.R1 or with a functional derivative thereof.  Exemplary of functional derivatives are: acetal, thioacetal, oxine and semicarbazone.  The resultant pyrimidine, if it contains halogen in the 2-, 4- or 6-positions, may be treated with ammonia or an amine to introduce the corresponding amino group in place of halogen.  Any of the 5-nitropyrimidines may be reduced to give 9 : 10-dihydropteridin derivatives: <FORM:0635582/IV (b)/2> whereof A and B, one is hydrogen, alkyl, amino or substituted amino, and the other is halogen, amino, or substituted amino.  In this reduction step, any group protecting the carbonyl group must be removed.  In examples: (1) 2 : 6-dichloro-5-nitro-4-methylpyrimidine in acetone is treated with sodium bicarbonate and aminoacetone hydrochloride to give 2-chloro - 4 - methyl - 5 - nitro - 6 - acetonylaminopyrimidine, which is (2) treated with diethylamine in dioxan to give 2-diethylamino-4 - methyl - 5 - nitro - 6 - acetonylaminopyrimidine, which is (3) hydrogenated in dioxan using Raney nickel to give 2-diethylamino - 6 : 8 - dimethyl - 9 : 10 - dihydropteridin.  In example (4) treatment of 2 : 6-dichloro-5-nitropyrimidine in a similar way gives 2 - chloro - 5 - nitro - 6 - acetonylaminopyrimidine, which on treatment with (6) benzylamine gives 2 - benzylamino - 5 - nitro-6-acetonylaminopyrimidine, and with (5) diethylamine gives 2 - diethylamino - 5 - nitro-6-acetonylaminopyrimidine, reduction of which (7) gives 2 - diethylamino - 8 - methyl - 9 : 10-dihydropteridin.  Eight other similar examples are given, in which 2-methyl-4 : 6-dichloro-5-nitropyrimidine, and 2 : 6- and 4 : 6-dichloro-5-nitropyrimidine are treated with aminoacetone, 2 - aminobutanone - 3, and aminoacetophenone, and the various products treated with amines and/or reduced to the dihydropteridins.  In example (15), 2 : 6-dichloro-5-nitropyrimidine is reacted with aminoacetal to give 2 - chloro - 5 - nitro - 6 - b  - diethoxyethylaminopyrimidine, which (16) with diethylamine gives 2-diethylamino-5-nitro-6-b -diethoxyethylaminopyrimidine; (17) 2 : 6-dichloro-5-nitropyrimidine is reacted with aminothioacetal to give 2-chloro-5-nitro-6-b -diethylthioethylaminopyrimidine, which (18) with alcoholic ammonia gives 2-amino-5-nitro-6-b -diethylthioethylaminopyrimidine; (19) 4 : 6-dihydroxypyrimidine is nitrated to give 4 : 6-dihydroxy-5-nitropyrimidine, which is treated with phosphorus oxychloride to give 4 : 6-dichloro-5-nitropyrimidine.
