摘要： A process for the purification of azo pigments, wherein the crude pigment is stirred for some time in an aqueous alkaline suspension in a pH range from 9 to 12, preferably from 11 to 12, at temperatures between 20.degree. to 80.degree. C and subsequently the crude pigment is filtered off and washed neutral. The pigments treated by this process show a clearer and more brilliant shade and are faster to bleeding when incorporated, for example, into a thermoplastic material than the untreated pigments.

摘要： The preparation of 3-amino-1-phenylpyrazol-5-one by heating phenylhydrazine and a lower cyanoacetic acid alkyl ester in a polar solvent, using a lower alcoholate of an alkali metal as the condensation agent, leads to particularly high yields and quality, if the phenylhydrazine and 1 to 1.2 moles of the alcoholate are initially taken, the cyanoacetic ester is metered in and the reaction is carried out at 105.degree. to 140.degree. C., volatile alcohols which have been liberated from the ester and, if appropriate, from the alcoholate being distilled off at the reaction temperature. It is advantageous to employ the phenylhydrazine in an excess of up to about 200 mole % and to select, as the polar solvent, an alcohol or ether having a boiling point above 105.degree. C.

摘要： The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls.According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR.sup.1, --CONHR.sup.2 or --NR.sup.3 COR.sup.4)in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.

摘要： The invention relates to monoazo pigments prepared from dichloroanilines as diazo components and CH-acidic coupling components of the acetoacetarylamide or naphthol series, these pigments only containing an extremely low level of polychlorinated biphenyls (PCBs) (at most 25 .mu.g per g of pigment).The process for preparing the pigments takes the form of an azo coupling in an aqueous medium, whereina) azo coupling is effected by adding the diazonium salt solution to a suspension or solution of the coupling component or by simultaneously metering the aqueous suspensions or solutions of the diazonium salt and of the coupling component into the reaction mixture,b) azo coupling is effected at a pH or within a pH range of less than pH 7 andb1) between pH 4 and 7 during and after azo coupling less than 0.05 mol-%,b2) at pH 2 to 4 during azo coupling less than 5 mol-%, andb3) at pH
