Liquid-liquid equilibrium (LLE) data for the ternary water + 2-methylaziridine + chloroform system have been obtained at 288.2, 298.2 and 313.2 K and under ambient pressure. Aziridines are used in paper, textileand photography industries. Data for binodal curves have been determined by cloud point method and conjugate points on the tie lines were obtained by correlating the refractive index curves as a function of composition. Extraction capability of chloroform, as the solvent, was revealed in terms of distributioncoefficient and separation factor. Distribution coefficient of 2-methylaziridine in organic/aqueous phases is lees than one; however, its separation factor is more than 180; indicating that 2-methyaziridine in aqueous solutions can be effectively extracted with chloroform. Furthermore, The NRTL and UNIQUAC models were used to correlate the experimental data. Results showed that both the models can representexperimental data satisfactorily (root mean square values of 0.0167 and 0.0188, respectively). The NRTL equation fitted the experimental data to some extent better than the UNIQUAC equation.
