Process for the preparation of dicarbonic acid salts for photographic purposes |
| abstract |
The invention relates to a method for producing anAmmonium or alkali salt of a di- or tricarboxylic acid,ncharacterized by reacting di / tricarboxylic acidnand / or di / tricarboxylic anhydride on the one hand and onenAmmonium and / or alkali hydrogen carbonate, on the other hand, in onenMixture that is a proportion of reaction mediators fromnContains 15 wt .-% or less. The method according to the inventionnenables inexpensive production of ammonium andnAlkalide or tricarboxylic acid salts in a solid phase reaction.nThe reaction products are without further workupnas a solid and can be formulated as a solidnphotographic reagents are processed. |
