摘要： An improved and novel process had been found for the esterification of aminophenol, amino-benzanilide and pyrazolone compounds containing a .beta.-hydroxyethylsulfonyl group, by means of sulfuric acid or sulfur trioxide which improvement is characterized by that the esterification is performed in a machine which is operating with a kneading action and effect, using per mol .beta.-hydroxyethylsulfonyl compound 1 to 2.5 times the equivalent molar amount of concentrated sulfuric acid, oleum or sulfur trioxide. This novel process has the great advantage that great amounts of sulfuric acid are saved which could charge the waste water, also in form of sodium sulfate formed after the required neutralization. Furthermore, the .beta.-sulfatoethylsulfonyl compounds formed as end-products in the esterification process are prepared by this novel process in higher yields, in a higher degree of esterification rate and in a higher purity. They are obtained in form of a powder or plastic mass from the kneading machine, which is well transportable and storable, and can advantageously used in the form of this consistency, without intermediate isolation of the pure .beta.-sulfato compound itself, directly for the preparation of azo dyestuffs which are poor of inert salts, possess a high tinctorial strength and purity.

摘要： The novel water-soluble disazo dyestuffs consist of two monoazo dyestuff moieties each containing as diazo component an amine of the benzene or naphthalene series and as coupling component an amino-naphthol-mono- or disulfonic acid. The two moieties are bonded to each other via a triazine radical which carries a halogen atom, and is bound to the amino groups of the coupling components and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. To produce the dyestuffs 2 mols of the diazo compound carrying the fiber-reactive radical of the vinyl sulfone series is coupled with 1 mol of a bivalent coupling component consisting of 2 radicals of the aminonaphthol bound to the triazine ring via the amino groups, or two monoazo dyestuffs each synthesized from the aforesaid diazo component and an aminonaphthol-disulfonic acid coupling component are reacted with a 1,3,5-trihalogeno-triazine. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by clear shades, high tinctorial strength, a very good uptake from a long liquor and a good color-build up. The dyeings obtained therewith have a high fastness to processing and in use.

The two moieties are bonded to each other via a bridge member bound to the amino groups of the coupling components and comprising two triazine radicals each containing a halogen atom, a sulfonic acid group or a thio ether or oxygen ether group or an amino group and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by a high tinctorial strength, a very good uptake from a long liquor, a good color- build up and good printing properties. The dyeings obtained therewith have a high fastness to processing and in use.
