      Additional pass to main patent no. '' 6 \ -278. Process for the preparation of an oxyacylaininoazo dye. The present patent relates to a list for the 1-line position of a new Oxvaeetvl- aiiiiiioazo dye and is therefore indicated, (1a1:

      one the llonoazo dye that inan by unite. obtained from dianotated 2-aniino-5-aeetvlaniinobenzene-1-sulphonic acid with 2-aniino-S-OYvnaphthalene-6-sulphonic acid in an acid medium, treated with etching agents and then the proportion of N. ( )

  - Aeetylprod = ukt converted into the 0zvaeetvlaininoazo dye by the action of saponifiers.



  In the example, parts mean elected parts. <I> Example: </I> 47 parts of the monoazo dye that you get through. Combination of diazotized 2-.4mino- 5 - acety laminollellzol -1- sulfonic acid with 2- amino-8-oxynaphthalene-6-sulfonic acid in an acidic medium,

   are added to the (-Teniiseh of 50 parts of loliolive oil and 150 parts of acetic acid anhydride at room temperature 'and stirred for several hours. The condensation is over as soon as no more free anionic group can be found Aeeton, the yellow leetviating product precipitating in a readily filterable form.

    It is filtered off, washed with aeeton and the residue is heated to 40 to 50 for a short time in a 5% soda solution for the purpose of splitting off the aerosol which has entered the body. Nian then salted out, filtered and dried. The resulting dye, a dark powder, dyes wool a brownish red color.

   Tones and domes smoothly with diazo compounds. It is released in concentrated sulfuric acid with a deep blue color, while the starting dye is red.
