Som organiska foreningar, vilka i kyla eller vid reaktionstemperaturen aro losliga i vatten, ifragakomma exempelvis foljande: metanol, etanol, propanol, butanol, glykol, glycerol, metylglykol, etyldiglykol, aceton, clioxan, dimetylformamid, Nmetylacetamid, butyrolakton, attiksyra, propionsyra, bensoesyra, p-toluensulfonsyra, p toluensulf amid, fenol, trietanolamin, anilin, kinolin, pyridin, N-metylpyrrolidon, metyletylketon eller tetrametylensulfon. In the further development of this inventive concept, it has now been found that rakinacridone can also be converted to its ykry crystalline phase. warms aqueous pastes of finely divided rakinacridone with such organic compounds, which are liquid at room temperature or under the reaction conditions and which have a solubility in water of at least 5% by weight, and which do not constitute the hydrocarbons or their nitro or halogen derivatives, at temperatures of about 80 -200 ° C, preferably about 100-180 ° C. As organic compounds which are soluble in water in the cold or at the reaction temperature, there may be used, for example, the following: methanol, ethanol, propanol, butanol, glycol, glycerol, methylglycol, ethyl diglycol, acetone, clioxane, dimethylformamide, N-methylacetamide, butyrolactone, attic acid, propionic acid, benzoic acid, p-toluenesulfonic acid, p-toluenesulphamide, phenol, triethanolamine, aniline, quinoline, pyridine, N-methylpyrrolidone, methylethylketulone or tetramethylketol.
Man forfar lampligen sa, att det fuktiga rakinakridonet blandas med den organiska foreningen och blandningen darefter varmes under omroring. Efter verkstalld omvandling isoleras reaktionsprodukten och torkas efter avlagsnandet av den for omvandlingen anvanda organiska foreningen genom tvattning med vatten, metanol eller en utspadd mineralsyra. Den f6r omvandlingen gynnsamma temperaturen är beroende av det anvanda rakinakridonet och av den organiska foreningen och ligger vid c:a 100-180° C. I de fall dar man arbetar Over reaktionsblandningens kokpunkt foretages omvandlingen i en omroringsbar tryekbehallare.

It is conveniently said that the moist rakina acridone is mixed with the organic compound and the mixture is then heated with stirring. After the transformation has taken place, the reaction product is isolated and dried after the removal of the organic compound used for the transformation by washing with water, methanol or a dilute mineral acid. The temperature favorable for the conversion depends on the rakinacridone used and on the organic compound and is at about 100-180 ° C. In cases where the boiling point of the reaction mixture is worked, the conversion is carried out in a stirring pressure vessel. For practical purposes, organic compounds are preferably used for the conversion which constitute major technical products and which can be regenerated from the aqueous mixtures.
