Title: Manufacture of new monoazo-dyestuffs
IPC: C09B45/16
Filed: 1952-02-20
Abstract: The invention comprises: monoazo dyestuffs of the general formula <FORM:0709495/IV(c)/1> (wherein X represents a sulphonic acid amide group and R the residue of a coupling component free from sulphonic and carboxylic acid groups and bound to the azo linkage in a position vicinal to a hydroxy group); the manufacture thereof by coupling a diazotized 4-nitro-2-aminophenol-6-sulphonic acid amide with a coupling component corresponding to the residue R; and a process for dyeing or printing therewith.  As diazo components may be employed heterocyclic amides, cycloalkyl or aralkyl amides of 4-nitro-2-aminophenol-4-sulphonic acid, or especially compounds containing a group -SO2 NHCn-1 H2n-1 where n=1-7.  Suitable coupling components are ortho-coupling phenols p  and naphthols, especially 1-acylamino-7-naphthols coupling in the 8-position, and enolized or enolizable keto-methylene compounds such as acylacetic amides (e.g. arylides), 5-pyrazolones coupling in the 4-position, 2:4-dioxyquinoline and barbituric acid.  The products may be treated with an agent yielding metal (e.g. chromium) in substance, in the dyebath or on the fibre (e.g. on wool by the after-chroming or the single-bath chroming process). Examples describe the preparation of the following dyestuffs: (1) 4 - nitro - 2 - aminophenol - 6 - sulphonic acid amide --> 1 - phenyl - 3 - methyl - 5-pyrazolone or b -naphthol; (2) the diazo component of (1) or the corresponding methylamide --> p-cresol.  A table gives the properties of the following additional dyestuffs: 4-nitro-2-aminophenol-6-sulphonic acid amide --> 4-methyl-2-acetylaminophenol, 4-acetylaminophenol, 1-acetylamino- or 1-benzoylamino-7-naphthol, 2:4-dioxyquinoline or 4-tert.-amylphenol; 4-nitro-2-aminophenol-6-sulphonic acid methylamide --> 1-benzoylamino- or 1-n-butyrylamino-7-naphthol; 4-nitro-2-aminophenol-6-sulphonic acid anilide-->3-methyl-5-pyrazolone.  A list of still further components is given.  In further examples: (3) wool is dyed with the first dyestuff of (1) from a bath containing acetic acid, sodium sulphate and, in the later stages, sulphuric acid, and then treated in the same bath with potassium dichromate, yielding a yellowish orange dyeing; (4) a similar dyeing is obtained by applying the same dyestuff from a bath containing sodium sulphate, potassium chromate, ammonium sulphate and, in the later stages, acetic acid. Specifications 430,926 and 709,493, [Group IV(b)], are referred to.

Abstract: 283,008. Kohlhaas, J. Feb. 18, 1927. Exhaust-silencers. - Exhaust enters a cylindrical casing a through perforations d and a slot e in a wedge-shaped end of a pipe c; some of the gas passes beneath a partition m and into a chamber o through a number of perforations q in a partition n and a slotted end s and perforations r in a tube t which is behind the central section of the casing; the remainder of the gas is ejected through slots k by gas passing through a slot f and along a passage h behind a series of vanes l protecting the slots k. This stream of gas escaping at the opening i assists in ejecting the gas from the chamber o through the same opening.

Abstract: 553,864. Synthetic resin compositions. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 9, 1941, No. 4724. Convention date, April 26, 1940. Drawings to Specification. [Class 2 (iii)] [Also in Group XXXV] Laminated core structures for transformers &c. such as described in Specification 540,662, [Group XXXV], comprise laminations of magnetic material bonded into a solid core by a heat-treated insulating composition composed of 20-80 per cent. of a polyvinyl acetal together with either or both polyvinyl acetate as plasticizer and a phenol-aldehyde heat-hardening resin up to a maximum of 20 per cent. The preferred acetal is that obtained by the reaction of acetaldehyde upon 70 per cent. hydrolyzed polyvinyl acetate ; other acetals are those derived from partially hydrolyzed polyvinyl acetates, propionates, butyrates or mixtures and formaldehyde, propionaldehyde and butyraldehyde. A solution of the resin in a mixture of alcohol and either toluene, xylene or solvent naphtha may be applied to the laminations, the solvent flashed off and the assembled laminations consolidated under beat and pressure; alternatively a wound core may be vacuum impregnated. Magnetic steel of very high permeability, obtained by cold rolling silicon steel and annealing under such conditions that the grains lie in the direction of easiest magnetization, may be employed for the whole or part of the core structure. The metal laminations may be chemically treated to form an adherent insulating scale, e.g. magnesium silicate, before applying the bonding material. Specific compositions are (1) the preferred acetal with 20 per cent. by weight of a cresylic acid-formaldehyde resin, (2) 42¢ per cent. of the acetal, 42¢ per cent. of polyvinyl acetate and 15 per cent. of cresylic acid-formaldehyde resin.
