Title: Process for the manufacture of azo dyestuffs
IPC: C09B43/02
Filed: 1933-04-25
Abstract: Monoazo dyes are obtained by treating with a sulphonating agent dyes of the general formula <FORM:0418458/IV/1> in which x and y represent H, alkyl or halogen (cf. Specification 22070/14, [Class 2 (iii)]), or by similarly treating the chromium complex compounds of such dyes (cf. Specification 414,381).  The sulphonation may be effected with fuming sulphuric acid of a high SO3-content at 125--150 DEG  C. or with sulphuric acid monohydrate at 75--110 DEG  C.  The products, in the form of their alkali metal salts, dye wool from an acid bath shades which on after-chroming are fast yellow to brown.  The following examples are specified.  The dyestuff 4 : 4<1>-dihydroxyazobenzene-3 : 3<1>-dicarboxylic acid is introduced into sulphuric acid monohydrate at a temperature not above 40 DEG  C. and stirred for 5 hours at room temperature, sulphur trioxide is added and the temperature is raised to 130--135 DEG  C. and so maintained for 3 hours; on cooling the mixture is poured on to ice, the precipitate is filtered and dissolved in dilute sodium carbonate and the sodium salt of the sulphonated dyestuff, which is mainly the 5 : 5'-disulphonate, is salted out; the product dyes wool shades which on afterchroming are clear greenish yellow.  (2) The dyestuff 4 - aminophenol - 2 - carboxylic acid --> 5 - methyl - 1 - phenol - 2 - carboxylic acid is similarly sulphonated to obtain a product dyeing wool shades which on after-chroming are clear yellowish brown; if the coupling component is replaced by 6-methyl-1-phenol-2-carboxylic acid, the shades are greener; if it is replaced by 5-chlorophenol-2-carboxylic acid, the shades are redder.  (3) The pyridine chromium complex compound of the dyestuff 4-aminophenol-2-carboxylic acid --> salicylic acid (cf. Example 5 of Specification 414,381) is heated with sulphuric acid monohydrate for 3 hours at 130--135 DEG  C.; on cooling the mixture is poured on to ice and the precipitate is filtered, washed with a solution of common salt until free from chromium and dissolved in sodium carbonate solution from which the sodium salt of the dyestuff (a mixture of 4 : 4<1>-dihydroxyazobenzene - 3 : 3<1> - dicarboxylic acid - 5 - mono - and 5 : 5<1> - disulphonic acids) is salted out.
