摘要:
对称C4二硫醚—丙酮—水三元体系是在合成对称C4二硫醚的工艺中碰到的一个比较新的体系.在常压308.15 K下,用浊点法,平衡釜法分别测定对称C4二硫醚—丙酮—水三元体系的溶解度数据和结线数据(对称C4二硫醚包括正丁基二硫醚、仲丁基二硫醚和叔丁基二硫醚),得到了三元液液平衡体系的共轭相组成并由此绘得相平衡曲线.用内标法准确地测定了对称C4二硫醚及丙酮的含量,在单相区域对实验进行了验证实验均方误差1.56％.对称C4二硫醚—丙酮—水三元体系的研究结果表明有利于回收对称C4二硫醚.研究有利于对称C4二硫醚清洁合成工艺的设计和控制.
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.
