Abstract�� The solubility of dimethyl ether in squalane is calculated by two group-contribution models proposed respectively by Larsen and Fredenslund under the conditions of T=503 K��573 K,P=0.1 MPa��2.0 MPa. Based on the calculated results of group-contribution models,the binary parameter for regular solubility theory is obtained from the optimization of the summation of residuals between the group contributions and regular solubility theory. In addition,the difference among them and their adaption ranges are pointed out in course of the investigation of the influences of temperature and pressure on the dimethyl ether solubility.
