ABSTRACT

The solubility of 1,3-Bis(9-carbazolyl)benzene (mCP) in 12 kinds of organic solvents, including methanol, ethanol, isopropanol, n-butanol, ethyl acetate, n-hexane, dichloromethane, toluene, acetonitrile, tetrahydrofuran, 1-methyl-2-pyrrolidinone and dimethyl sulfoxide was measured at 283.15 to 313.15 K and atmospheric pressure by using the isothermal saturation method. The experimental data in all solvents were correlated by the modified Apelblat equation. The results showed that the increase of temperature would lead to the increase of mCP solubility and the correlated values based on modified Apelblat equation agreed well with the experimental values. The maximum value of root-mean-square deviation was 3.44 * 10- 3. Moreover, 1-methyl-2-pyrrolidinone with high solubility from measuring data was used as solvent to carry out solvent antisolvent precipitation experiments in both conversional stirred tank reactor and rotating packed bed. Under different experimental conditions, the size distribution of precipitation products varied greatly from 33 nm to 3.2 im and the shape features varied from clavate crystals and stacked ellipsoids.
