Pigment Red 122 Use and Manufacturing
In a 1 L three-necked flask equipped with an electrically heated magnetic stirrer, a thermocouple and condenser (distillation unit) were installed. , In three84.5 g PPA (0.25 mol) of polyphosphoric acid was added to the flask, and after 3 hours at 100 ° C, 18.8 g of 2, 5-dimethylAniline terephthalic acid (0.05mol), add the material, the reaction at 125 3h, stop the reaction. The crude product 2, 9-dimethylquinacridone 16.93g, yield 99.59percent.Example12; 2000 g of phosphoric acid 85.0percent are placed at 20-25° C in a 10000 ml'All In One Reactor M) of (Drais Mannheim Germany) followed by the. slow addition of 2000 g of P2O5 under stirring and letting the temperature to go up to 80° C. Thereafter 1500 parts of 2, 5-di-(4- toluidino) terephthalic acid (Formula V wherein R2=R3-4-CH3) are added thereto under stirring and nitrogen flow. The mixture is now heated to 120° C within 30 minutes and maintained at 120° C for 30 minutes. Thereafter, the mixture is heated to 130° C in 15 minutes and kept at 130° C for one hour. The mixture is cooled to. 70° C followed by metering in of 3000 ml of isobutanol over a period of 2 hours with external cooling, and thereby allowing the temperature to reach the maximum reflux temperature of isobutanol. The mixture is stirred at reflux temperature for one hour, cooled to 70° C and emptied into a stainless steel container. The resulting product is colleted by filtration and reslurried in water containing sodium hydroxide to pH greater than 10. The slurry is heated at 90° to 95° C. for one hour. then again collected by filtration, washed until free of alkali, and dried to give 1316 g (97percent theory) of the compound. of the formula SXVII.Example 7 ; 5000 g ofpolyphosphoricacid containing. 85. 0percent P. sub. 2 O. sub. 5. and 1250 parts of 2, 5-di- (4-toluidino) terephthalic acid (Formula V wherein R2=R3= 4-CH3) are placed at 20-25° C in a 10000 ml'All In One Reactor' of (Drais Mannheim Germany). Under stirring and nitrogen flow the mixture is heated to 120'C, within 3 0 minutes and maintained at i20. C for 30 minutes. Thereafter, the mixture is heated to 130 C in 15 minutes and kept at 130 C for one hour. The mixture is cooled to 70 C followed by metering in of 3000 g isobutanol over a period of 2 hours with external cooling, and thereby allowing the temperature to reach the maximum reflux temperature of isobutanol. The mixture is stirred at reflux temperature for one hour, cooled to 70 C and emptied into a Steel container. The resulting 2, 9- dimethylquinacridone 1AVILI is colleted by filtration and reslurried in water containing sodium hydroxide (pH greater than 10). The slurry was heated at 90 to 95. degree. C. for one hour, then collected by filtration, washed until free of alkali, and dried to give an 85percent yield of quinacridone of the formula XXVII (95percent purity).
