  <B> Additional patent </B> to main patent No. 232121. Process for the production of a raw material derivative. It was found @that mam. arrives at a new urea derivative,

   which at the same time is a valuable azo substance. if one on 2 times: der 2-M.ethyl-4- (4 "- amnn @ o) - bonzayl: amina - 2 '- oxy, -1,1'-azob @ enzol- 3'-ca.rbansäure- 5'-sulfonic acid allows 1 mol of phosgene to act.



  The new dye is a 'brown powder: that. Cotton in a very awake alkaline bath to which a copper salt solution of copper sulfate and tartaric acid sodium has been added, dyes in a washable, reddish yellow shade.

      <I> Example: </I> 70.2 of the Mon @ oazo @ color: substance made from: diazotized 1-amino-2-oxybenz, ol-3-carbogy-5-sulfonic acid and 1-methyl-3raminobenzene are used as sodium salt with the addition of 27 parts by weight of sodium acetate in 500 parts by weight of water:

  solved. This solution is treated at about> 60 with 3.9 parts by weight of 4-nitrobenzoyl.chlori, d to which 10 parts by weight of acetone have been added.

    Idas, formed nitrobenzzo.yl product is reduced with 84 parts by weight of crystallized sodium sulfide, which were dissolved in 150 parts by weight of water, at 65 = 70 to the aminobenezoyl product. The.

       The deposited reduction product is dissolved in 4000 parts by weight of water with the addition of nabrium carbonate until a clear alkaline reaction is obtained and treated with phosgene for 24 hours with stirring at ss0'-40 until no free NHZ!

  e more naeh- w @ eis @ en lets. The urea derivative, which has been mixed out, is precipitated as sodium salt, filtered and dried.
