    摘要： The N-acetoacetylamino compounds of 2,5-dimethoxy-4-chloro-aniline, 2,4-dimethyl-aniline and 2-methyl-5-chloroaniline are obtained in a good yield and excellent purity, if the above-mentioned anilines are reacted with diketene in an inert organic solvent or diluent in the presence of from 0.1 to 6%, calculated on the weight of the aniline, of water, while adding catalytic amounts of acid. An industrial aniline quality is preferably dried by heating it with a solvent forming with water an azeotropic mixture, and thereafter the amount of water required is added. The products may be used without purification as coupling components for the preparation of pigments.

    摘要： The invention relates to a process for the preparation of aryldiazosulfonates by reacting aqueous solutions of aryldiazonium salts with solutions or suspensions of sulfites, in particular in a manner such that the presence of an excess of one of the two reactants during the reaction is substantially excluded. The process according to the invention makes it possible substantially to increase the yields of aryldiazosulfonates.
