Diazoles

Diazoles

 

stabilized diazonium salts. The salts are usually stabilized as a result of the formation of double salts with ZnCl2 or of salts with naphthalenedisulfonic acid. To eliminate their explosiveness, diazoles are mixed with inorganic salts. They are used for the smooth dyeing of cellulose fibers, yarn, and cloth (rarely wool and natural silk), as well as for printing on cloth, in various colors. In this process, water-insoluble azo dyes are produced as a result of nitrogen coupling in the fiber pores.
