Abstract

2:4 - Dichloro -6- methylpyrimidine -5- sulphonic acid chloride is made by treating with phosphorus pentachloride and phosphorus oxychloride 2:4-dihydroxy -6- methylpyrimidine -5- sulphonic acid chloride which is obtained by reacting 2:4-dihydroxy-6-methylpyrimidine with chlorosulphonic acid. 2:4-dichloro - 5 - (p-amino benzyloxymethyl)-6-methylpyrimidine and 2:4-dichloro - 5 - (m-amino - p - sulphophenylaminomethyl)-6-methylpyrimidine are made by reacting 2:4-dichloro-5-chloromethyl-6-methylpyrimidin respectively with p-aminobenzyl alcohol and 1:3-phenylene -diamine-4-sulphonic acid.ALSO:The invention comprises water-soluble organic dyes which (a) contain at least one halogenate pyrimidine ring attached via an amino, ether or thioether group, the ring bearing in the 5-position a negative substituent other than a halogeno-alkyl group and in the 6-position hydrogen, alkyl or a carboxylic acid ester radical, or (b) contain at least one dihalogeno pyrimidine ring joined to an amino, ether or thioether group of the dye through an alkylene or a halogeno-alkylene group in the 5-position, the pyrimidine ring bearing in the 6-position hydrogen, alkyl or a carboxylic acid ester radical. By the term " negative substituent " is meant the following groups: halogenoalkyl, nitro, nitrile, carboxylic acid, carboxylic acid amide, carboxylic acid ester, sulphonic acid, sulphonic acid chloride, sulphonic acid amide which may be substituted at the nitrogen and sulphonic acid ester. The dyes are made by condensing an organic dyestuff containing at least one water-solubilizing group and at least one hydroxy, thiol or amino group or an organic dyestuff intermediate containing at least one hydroxy, thiol or amino group with a pyrimidine of the formula: <FORM:0958026/C3/1> where x is a negative substituent and y is hydrogen, alkyl or a carboxylic acid ester radical, and, when an intermediate has been used, converting the product into a dyestuff by azo coupling or condensation. When x is a halogenoalkyl group, dyes of the type (b) above are obtained and when x is a negative substituent other than halogenoalkyl then dyes of type (a) are obtained. Examples of dyes of the anthraquinone, phthalocyanine, monoazo, disazo, metallized azo and stilbene series are given. The dyes dye, pad and print wool, silk, synthetic polyamides such as nylon, leather and natural or regenerated cellulose fibres.
