Patent GB-422317-A (GB)
Title: The manufacture of azo-dyestuffs insoluble in water
IPC: C09B29/20
Filed: 1934-05-18
Abstract: Azo dyes insoluble in water are made by diazotizing an amine of the general formula <FORM:0422317/IV/1> (in which one X = H, alkyl or phenyl, and the other X = alkyl or phenyl-) and coupling with an arylide of 2 : 3-oxynaphthoic acid. They may be produced in substance, on a substratum or on the fibre.  They yield clear fast yellow to golden-orange shades.  In an example the following dyestuff is produced on cotton 1 - amino - 2 - benzylsulphone - 4 - methyl-sulphone - benzene --> 1 - (2<1> - oxy - 3<1> - naphthoylamino)-2-methyl-4-chlorobenzene.  In a table the shades obtained by use of the following additional components are given: 1-amino-2-benzylsulphone-4-ethylsulphone-benzene, 1 - amino - 2 - methylsulphone - 4 - benzylsulphone - benzene, 1 - amino - 2 : 4 - dibenzylsulphone - benzene; the anilide, o-toluidide and p-chloranilide of 2 : 3 - oxynaphthoic acid.  Specifications 6379/12, [Class 2 (iii)], and 17279/13, [Class 15 (ii)], are referred to. Aminobenzenedisulphones are made as follows: aniline is converted into 2-amino-6-thiocyanobenzothiazole by the action of an excess of ammonium thiocyanate and bromine in the presence of glacial acetic acid with the intermediate formation of 2 : 4 - dithiocyanoaniline. The 6-thiocyano group is then saponified to the mercapto group which is alkylated or aralkylated.  The 2-aminobenzothiazole-6-thioethers are converted according to Specification 306,590, [Class 2 (iii)], into 1-amino-benzene-2-mercapto-4-thioethers which are then further alkylated or aralkylated on the free mercapto group.  In this way unsymmetrically substituted dithioethers can be obtained.  The symmetrical substituted dithioethers may be obtained by converting the 2-amino-6-thiocyanobenzthiazole into 1 - amino - 2:4 - dimercaptobenzene (cf. Specification 306,590) which is then dialkylated or diaralkylated.  The dithioethers are converted into the disulphones by acetylation of the amino group, oxidation with hydrogen peroxide in glacial acetic acid and saponification. Specifications 257,619 and 295,295, [both in Class 2 (iii)], also are referred to.
Patent GB-1057186-A (GB)
Title: Improvements in or relating to vinyl halide polymers
IPC: C08F14/20
Filed: 1964-04-13
Abstract: A process for preparing vinyl fluoride polymers of controlled particle size comprises polymerizing in a reactor at moderately elevated temperature and under superatmospheric pressure a monomeric material comprising at least 50% of vinyl fluoride monomer suspended in an aqueous medium in the presence of a free-radical generating polymerization catalyst and reducing the size of the individual monomer droplets dispersed in the aqueous medium to substantially less than one micron in diameter by subjecting the reaction mixture to high shearing and impaction forces, whereby the droplets, when so reduced in size, are inhibited from coalescing into monomer droplets comparable in size to those which are obtained at lower shearing and impaction forces, and polymer products are produced therefrom are composed of particle agglomerates of controlled size.  The forces may be applied by an agitator in the reactor, e.g. with a tip speed in excess of 600 feet per minute and with a clearance of no more than 3 inches between the tip and the reactor wall, or by circulating the reaction mixture through a dispersing device adjacent to the reactor. Small proportions of surface active agents may be added to the reaction mixture.  The monomeric material may comprise minor proportions of di-, tri- and tetrahaloethylenes, vinyl esters, vinyl ketones, vinyl ethers, olefins, and acrylic, methacrylic, maleic and fumaric acids and the anhydrides, acid halides, nitriles, amides and esters thereof.  Examples describe the polymerization of a suspension of vinyl fluoride in water in the presence of lauroyl peroxide, isopropanol, methyl cellulose and magnesium lauryl sulphate using rapid agitation and circulation through an adjacent dispersing device to effect the desired dispersion. The dispersions may be used for coating.
