Additional patent to the main_patent no. <B> 222255. </B> Process for the production of the leuco-sulfuric acid ester of a nub dye of the anthi-aquinone series. The subject of this patent is a process for the preparation of the leucosulfuric acid ester of a vat dye of the anthraquinone series, which consists in the dye,
which is obtainable by coupling the diazotized 1-aminoanthraquinone with acetoacetic acid-2-m, ethoxy-4-chloroanilide, by treatment with a reducing agent and an esterifying agent which provides sulfur trioxide in the presence of a tertiary base, into the leucoselulfuric acid ester .
The conversion of the vat dye into the leuco-sulfuric acid ester takes place in the usual way, e.g. by treating .des dye, in the presence of a tertiary, -, ren base, such as. B. pyridine ,. and a sulfur trio, xyd provide # den- esterification agent, such as e.g. Chlorosulfonic acid or chlorosulfonate, with a metal, e.g.
B. with copper eder iron. For working up, the reaction mixture is expediently added to a solution of sodium carbonate or sodium hydroxide, or ammonia in water, in a suitable manner, e.g. by distillation in vacuo from the tertiary. Baee freed and filtered off from the metal salts. The leuco-sulfuric acid ester formed can be obtained from the filtrate in the form of a salt,
e.g. in the form of the sodium salt or potassium salt, obtained by salting out with sodium chloride or potassium chloride. The precipitated alkali metal salt, the leuco sulfuric acid ester is. It is filtered off and a little sodium carbonate is added to increase the shelf life.
<I> Example: </I> In <B> 800 </B> parts by weight of a pyridine fraction with a boiling point of about, <B> 125-126 'C </B> is allowed to <B> 150 <with stirring and cooling / B> parts by weight of Clilo # reulfoneure - and carries <B> 100 </B> parts by weight of the dye, which is obtained by coupling diazotized 1-aminoanthraquinene with acetoacetic acid-2-methoxy-4-chloroanilide
and <B> 60 </B> parts by weight of iron powder. The reaction mixture is briefly heated to 40-50 <B> 'C </B>. As a result of the heat of reaction, the temperature rises to <B> 60 ° C. for a short time. After stirring for one hour, the esterification mixture is added to a solution of <B> 2930 </B> parts by weight of sodium carbonate in 4000 Ge parts by weight of water, distilled in a vacuum pyrid, infrei,
filtered from the iron sludge and salted the sulfuric acid ester from the fil emerged with approx. 15% sodium chloride. The precipitated ester is filtered off, washed with sodium chloride solution and washed with approx. 2 <B>% </B> sodium carbonate pasted. The eo, obtained leuco sulfuric acid ester is easily soluble in water and is treated in the usual way with acidic oxidizing agents,
on the fiber a nice neutral yellow with very good fastness properties.
