YieldReaction ConditionsOperation in experiment
A one-liter flask equipped with a stirrer, thermometer, condenser and drying tube is charged with 250 mi concentrated (95-98%) sulfuric acid. 19.5 g 2, 9-dichloroquinacridone pigment (CINQUASIAO Magenta RT-265-D, Ciba Specialty Chemicals Inc.) are added at a temperature of 50oC and the mixture is stirred for 20 minutes at 48-52oC to dissolve the pigment. 19.9 g of a wet naphthalene sulfonic acid sodium salt presscake with a solid content of 58%, a mixture containing 80% 1-naphthalene sulfonic acid sodium salt and 20% 2- naphthalene sulfonic acid sodium salt (Shanghai Shen Li Chemical Factory) are added at a temperature BELOW 50oC and the mixture is stirred for 30 minutes at 45-50oC followed by the rapid addition of 1.6 G PARAFORMALDEHYDE. The reaction mixture is stirred for one hour at 58-60oC then poured into 2.5 liter ice water. The violet precipitate is stirred for 1 hour at 5-20oC, and then filtered. The violet press cake is washed with little water to a pH of 1.5-2. 5 and kept as presscake. About 0.5 g of the press cake are RESLURRIED in 20 ml hot water, yielding a violet colored liquid which is filtered through paper to remove little aggregated material. The filtrate is violet and appears like a dye solution. However, the electron micrograph shows the 2, 9-dichloroquinacridone in nanosize particle form with an average particle size of from 10 to 25 nm.
