摘要：改进了Proust等测定液-固平衡的装置和方法,并用该装置测定了2,6-二甲基苯酚在环己烷中和2,4-二氟苯甲醛在乙醇、丙酮、乙酸中的溶解度,测温误差为0.04K,液相组成误差为0.000 5。
An improved version of the method and instrument of solid-liquid equilibrium has been calibrated. The solubility of 2,6-dimethylphenol in cyclohexane was measured by this equipment and the data agree with literature values. On this basis, the solubilities of 2,4-dichlorobenzaldehyde in ethyl alcohol, acetone, acetic acid were measured accurately and correlated by UNIQUAC activity coefficient model. Those data can be used as the basis of selection of the process parameters in purification and crystallization of 2, 4-dichlorobenzaldehyde.
