摘要： A new method of diazotization consists in using as the diazotizing agent in an aqueous, aqueous organic or organic medium the system comprising salt of nitrous acid+acid insoluble in the reaction medium, in particular organic or inorganic cation exchangers having acid groups. The diazonium salt solutions thus prepared are immediately reacted with coupling components to give azo dyestuffs, the insoluble acid and/or its salt being separated off before or after the coupling.

摘要： Highly concentrated liquid preparations of disperse dyestuffs are obtained with a low consumption of energy by first adding a dispersing agent to the water-moist dyestuff press-cake to convert it into a form in which it is capable of flow, subjecting this product to wet grinding and increasing the dyestuff content of the resulting, insufficiently concentrated dispersion in a second step by means of a membrane separation process, for example pressure permeation.
