- Abstract:
- The terary system symmetrical C4 disulfide + acetone + water in the process for the synthesis olsymmetrical C4 disulfide is a relatively new system, The data of liquid-liquid equilibrium (tie-lines and solu-bility ) for the ternary system symmetrical C4 disulfide + acetone + water were determined at almospherie pres.sure and at 308. 15 K, using cloud point method and halance reactor method. ( Symmetry C4 disulfide inclu.ding n-butyl disulfide, sec-butyl disulfide and tert-butyl disulfide). The composition of the conjugate phase ofthe ternary liquid phase equilibrium system was determined and the equilibrium curve was drawn finally. Theinner-sealing method was used to determine the concentration of symmetrical C4 disulfide and acetone in thisternary system. Experiments in single-phase region was verified, and the accuracy of experimental error is1.569 rms. Study on the phase equilibrium of the terary system symmetric C4 disulfde + acetone + watershows it is very favorable for the recovery of symmetrical C4 disulfide. The study is essential for clean synthesisof symmetrical C4 disulfdes to design and control.
