Definitions

  • Y stands for halogen
  • Me stands for a metal of the group consisting of Zn, Cd and Sn
  • the diazo salts may be obtained by diazotizing unilaterally 1,4-diaminobenzenes, halogenated in the nucleus and being free. from sulfonic acid or carboxylic acid groups, 1. e. by treating the said 1,4-diaminobenzenes with thequantity of mineral acid and nitrous acid, necessary for diazotizing one amino group, and by precipitating the diazo compounds, thus obtained, in the form of stabilized diazo compounds, such as, for instance, zinc chloride-, tin chlorideor cadmium chloride-double salts.
  • stabilized diazo compounds such as, for instance, zinc chloride-, tin chlorideor cadmium chloride-double salts.
  • diaminobenzenes could be transformed in a smooth reaction into aminodiazonium salts in the presence of mineral acid and it could, fur thermore, not be foreseen whether these monodiazo compounds could easily be precipitated and whether they would be stable enough for being used on an industrial scale as dyeing salts.
  • Heep-NP Z1101, 1 2 Q is salted out by addition of sodium chloride, worked up as usual and, if desired, adjusted to the usual commercial form by addition of, for instance, anhydrous sodium sulfate or partly dehydrated aluminium sulfate.
  • the salt is very stable and easily soluble.
  • the precipitation may also be effected by means of a zinc chloride solution which has a small content of SnCLi.
  • diazonium zinc chloride double salts of other halogen-lA-diaminobenzenes for instance, of 2-ch1oro-, 2-ch1oro-5-methy1- and 2- chloro-fi-bromo-lA-diaminobenzene.
  • Y stands for halogen
  • Z stands for one of the group consisting of hydrogen, halogen and alkyl
  • Me stands for a metal of the; group consisting of Zn, Cd and Sn, and m for a num- 25 her corresponding to the highest valence of the metal signified by Me, being very stable and easily soluble in water.
  • Y stands for halogen
  • Z stands for one wherein Me stands for a metal of the group consisting of Zn, Cd and Sn, and m for a number. corresponding to the highest valence of the metal signinfied by Me, being very stable and easily soluble in water.
