Abstract: Acylacetic hydroxy arylamides are obtained by condensing aromatic monoamines containing free hydroxyl groups with acylacetic esters, by heating in a solvent or excess of the ester. According to examples, amides are prepared from acetoacetic ester and 1-amino-3-hydroxybenzene, 1-amino-3-hydroxy-6-chlorobenzene, 2-amino-7-hydroxynaphthalene, 1-amino-5-hydroxynaphthalene, 2-hydroxynaphthalene-3-carboxylic acid-3<1>-amino-anilide; from 1-amino-3-hydroxybenzene and propionyl-acetic ethyl ester, benzoylacetic ester, p-nitrobenzoylacetic ester, terephthaloyl-bis-acetic ester, isophthaloyl-bis-acetic ester, diphenyl-4 : 4<1>-di-(carboyl acetic ester), and naphthalene 1 : 5-di-(carboyl acetic ester); from 1-amino-3-methyl-4-hydroxybenzene and terephthaloyl-bis-acetic ester; from 2-hydroxynaphthalene-3-carboylamino - 4<1> - amino - 2<1> : 5<1> - dimethoxy benzene and benzoylacetic methyl ester and terephthaloyl-bis-acetic ester.  Pyrazolones such as 1-(m-aminophenyl)-3-methyl-5-pyrazolone are also referred to as suitable aminophenols.  The preparation of some of the b -ketonic esters employed is described in Specification 365,531. 1-Amino-3-hydroxy-6-chlorobenzene is obtained by acetylating, chlorinating and saponifying, m-aminophenol.

Patent GB-1007341-A (GB)
Title: Process for preparing polymers from open-chain n-vinyl amides
IPC: C08F26/02
Filed: 1962-07-11
Abstract: N-vinyl amide polymers are produced by polymerizing one or more open-chain N-vinyl amides in an aqueous medium at 0-100 DEG  C. in the presence of 0.0001-10% each of hydrogen peroxide and of at least one inorganic and/or organic basic nitrogen containing compound. The N-vinyl amide may be of formula <FORM:1007341/C3/1> where R1 and R2 are C1- 5 alkyl groups or H, and may be N-vinyl N-methyl acetamide N-vinyl acetamide, N-vinyl N-methyl proponamide or N-vinyl N-methyl-i-butyramide. The N-vinyl amide (at least 10%) may be copolymerized with a monomer capable of polymerizing under the action of a free radical catalyst, e.g. acrylonitrile or N-vinyl pyrrolidone. The basic compound may be ammonia, hydrazine or a C1- 5 primary aliphatic monoamine. The polymerization may be carried out in the absence of oxygen, e.g. in nitrogen.  The pH of the aqueous medium is at least 7 to prevent hydrolysis of the N-vinyl amides.
Patent GB-722963-A (GB)
Title: Moulding articles having a metal layer thereon, e.g., mirrors and reflectors
IPC: B32B15/08
Filed: 1952-10-24
Abstract: A moulded article, e.g. a mirror or reflector, is provided with a metal coating at the same time as it is moulded, by first applying a layer of varnish on the mould, then applying a layer of metal on the varnish, and finally moulding the article in the thus-prepared mould. This yields an article having a metal layer covered with varnish. The varnish may be removed or left on to provide a protective layer. Varnishes are used which do not stick to the mould, e.g. a solution of cellulose acetate or a varnish containing polyvinyl chloride or vinyl chloride-acetate polymer. If necessary, adherence to the mould may be reduced by using a parting agent.  Adherence of the varnish to the metal also may be prevented by using a parting agent, or may be ensured as by applying an adhesive between the varnish and the metal layer. Adherence between the metal layer and the mass of the article may be ensured by an adhesive, e.g. an emulsion of polyvinyl acetate in water.  The mass of the article may be thermoplastic or thermosetting synthetic resin, natural resin, bitumen, gypsum, cellulose fibre or low melting point alloy.  The metal may be applied to the varnish by spraying or evaporating, or by bringing a solution of a metal salt containing a reducing agent into contact with the varnish.  The metal may be aluminium, silver or chromium.  In an example, a conical aluminium mould is wetted with a solution of a parting agent (aluminium stearate or "Vaseline" (R.T.M.) in trichloroethylene), the solvent is vaporized, a varnish comprising cellulose acetate dissolved in acetone and ethyl lactate is poured on the mould, the solvent is caused to evaporate, the layer of varnish is dried, a layer of aluminium is applied to the varnish by vaporizing from a cathode in a vacuum, an adhesive (emulsion of polyvinyl acetate in water) is painted on the aluminium, and on the thus prepared mould a suspension of cellulose fibres in water is applied as described in Specification 683,908.  After drying, the reflector thus obtained is removed from the mould and the cellulose acetate varnish, which is not firmly attached to the aluminium, may be readily removed, as by dissolving.  If the varnish is to remain on the aluminium, a coating of ethyl cellulose in toluene is provided therebetween. This example may be modified by providing a layer of alkoxylated urea formaldehyde pre-condensate dissolved in white spirit between the cellulose acetate varnish and the metal layer, this layer being fired at 120 DEG C. before the aluminium is applied. Then the main mass of the article, e.g. polystyrene, is moulded on to the metal layer, the article is cooled, and the cellulose acetate varnish is removed to expose the thermoset urea formaldehyde resin.

Abstract: Hydrocarbon oils boiling above 300 DEG C are desulphurized by treatment with a gas containing free hydrogen at a temperature above 200 DEG C and under a pressure of at least 10 atmospheres in the presence of a stationary catalyst, by letting the oils flow in a thin layer over the catalyst in a reaction space through which the gas containing free hydrogen is passed as a single continuous phase, the quantity of hydrogen discharged from the reaction space (calculated at normal temperature and pressure) being at most 500 litres, but preferably more than 50 litres, per kgm. of initial material.  The gas may be pure hydrogen or hydrogen mixed with other gases, such as hydrocarbons, nitrogen and carbon oxides.  A temperature of 250 DEG -450 DEG C may be used.
