    Abstract: Textile materials, such as those of natural or regenerated cellulose, cellulose esters, polyamides, polyesters or polyacrylonitrile, are dyed or printed, and if desired quality finished, by applying a dye of the tetrazaporphin series, such as a metallised or unmetallised phthalocyanine, which contains one or more sulphonic acid hydrazide groups. or an N-methylol or etherified N-methylol derivative of such a dye, and also applying, together with or after the dye, an acid or acid-reacting substance and a hardenable aminoplast, or the initial materials for forming the same, and finally heating. When the dye contains N-methylol groups, treatment only with the nitrogenous component of the aminoplast may be applied. The dye may also be converted into its N-methylol derivative on the fibre by treatment with an alkaline formaldehyde solution. Specified hardenable aminoplasts are dimethylolurea, dimethyldimethylolurea, dimethyloldicyandiamide, methylolthiourea, dimethylolguanidine, trimethylolmelamine, diphenyldimethylolurea, and methylol derivatives of monoureines, diureines, carboxylic acid amides and diamides, urethanes, polyurethanes, hexahydro - keto - triazines, lactams, polyamides and ethylene ureas. Specified acids and acid-reacting substances are boric, phosphoric, formic, acetic, glycollic, tartaric, chloracetic, chlorpropionic, citric and maleic acids and ammonium chloride and diethanolamine hydrochloride. The dyes are prepared by reacting tetrazaporphin derivatives containing sulphonic acid chloride radicals with hydrazines, such as hydrazine itself, methyl-, ethyl-, propyl-, butyl-, cyclohexyl-, phenyl-, and benzyl-hydrazine, 1 - hydrazino - benzene - 4 - sulphonic acid, acetly-hydrazine, benzoyl-hydrazine, semicarbazide, thiosemicarbazide and aminoguanidine. The dyes may also contain sulphonic acid groups, and are converted into their N-methylol derivatives by treatment with alkaline formaldehyde solution, and, in turn, into their etherified N-methylol derivatives by treatment with alcohols in the presence of acids. Examples of dyeing, and of the preparation of the dyes used therein, are given.

    Abstract: In a process for the production of watersoluble salts of alpha, beta-ethylenically unsaturated sulphonic acids, beta-chlorethane sulphochloride or a beta chlorethane sulphochloride which is substituted in alpha- or beta-position is reacted in aqueous solution with an oxide, hydroxide or carbonate of a metal of Group IA or IIA or of magnesium or zinc oxide, lead oxide or copper oxide or an hydroxide or carbonate of ammonia. p Additional specific metal compounds referred to are sodium and potassium carbonates and hydroxides of lithium, sodium, potassium, magnesium, calcium and barium. The examples relate to the preparation of sodium, potassium, calcium, barium and ammonium vinyl sulphonates from beta-chlorethane sulphochloride. Alpha-or beta-position substituents which may be present in the starting materials include alkyl, halogen alkyl, aralkyl and aryl groups and additional starting materials specified include 1,3-dichlorpropane-2-sulphochloride, 1,2-dichlorpropane-3-sulpho-chloride, 2-chlorpropane-1-sulphochloride, 2,3-dichlorbutane-1-sulphochloride, 2,3-dichlorbutane-1,4-disulphochloride and 1-chlor-1-phenylethane sulphochloride. Specific metal hydroxides mentioned for use in the process include lithium, sodium, potassium, magnesium, calcium or barium pydroxide. The production of sodium, potassium, calcium, and barium vinyl sulphonates from beta-chlorethane sulphochloride is described.
