Abstract

Thiourmium salt of N-tetradecyl-p chloromethylbenzenesulphonamide is prepared by reacting tetradecylamine with p-chloromethylbenzene-sulphonyl chloride in alcoholic solution containing potassium acetate to give N - tetradecyl - p - chloromethylbenzenesulphonamide. This is reacted with N,N,N1,N1-tetramethylthiourea to give the thiouronium salt. The thiouronium salt of formula IIIE <FORM:0990971/C2/1> is prepared by reacting cyanuric chloride with N1 - tetradecylsulphanilamide in cold acetone with sodium carbonate present and reacting the product with N,N,N1,N1-tetramethylthiourea. Specifications 864,474, 864,475 and 963,433 are referred to.ALSO:Thiouronium salt of an azo dye of formula IB2 <FORM:0990971/C4-C5/1> is prepared by coupling Naphthol AS-LG (C.I. 37615) and Fast Red Salt FRN (C.I. 37075). This compound is dissolved in sulphuric acid, chloromethyl methyl ether added and heated. This chloromethylated compound is heated with N,N,N1,N1-tetramethylthiourea to give the azo dye. Thiouronium salt of a dye of formula IB3 <FORM:0990971/C4-C5/2> is prepared by chloromethylating Indigo Yellow (C.I. 73100) in sulphuric acid with bis(chloromethyl) ether. The product is added to molten N,N,N1,N1-tetramethylthiourea and heated to give the azo dye. An azo dye is prepared by coupling the benzoylacetanilide produced by condensation of ethyl benzoyl-acetate and 2,5-dimethoxyaniline with the diazo compound obtained from the amine which is produced by condensing p-acetyl-aminobenzene sulphonyl chloride with N,N-diethyl-ethylenediamine followed by hydrolysis of the acetyl group. This dye is reacted with phenacyl bromide in alkali to give the dye of the formula IB4(a) <FORM:0990971/C4-C5/3> Alternatively the azo dye may be reacted with bis(chloro-methyl) ether in acid and this product reacted with N,N,N1,N1-tetramethylthiourea to give a dye of formula IB4(b) <FORM:0990971/C4-C5/4> A thiouronium salt of dye of formula IC1 <FORM:0990971/C4-C5/5> is prepared by reacting Basolan Chrome Brilliant Red 3BM with thionyl chloride and then reacting the chlorinated product with p-nitro-aniline. This nitro compound is reduced with iron and reacted with chloracetyl chloride. This product is reacted with N,N,N1,N1-tetramethylthiourea to give the dye of the formula Thiouronium salt of a dye of formula IC2 <FORM:0990971/C4-C5/6> is prepared by chloromethylating Anthrogen Red Violet RHC (C.I. 73385) and reacting with N,N,N1,N1-tetramethylthiourea. Similarly the thiouronium salt of Naphthol AS azo dye of formula II <FORM:0990971/C4-C5/7> is prepared from the azo dye. The azo dye of formula III A <FORM:0990971/C4-C5/8> is prepared by reacting Naphthol AS-LG (C.I. 37615) with Fast Red Salt ITRN (C.I. 37150). The thiouronium salt of the dye of formula III F <FORM:0990971/C4-C5/9> is prepared by refluxing p-chloromethylbenzoyl chloride and 1,5-diamino-anthraquinone and then reacting with N,N,N1,N1-tetramethylthiourea. Specifications 864,474, 864,475 and 963,433 are referred to.
