摘要:
从简化生产工艺、降低分离过程能耗及一次性将乙酸乙酯浓度提高到99.5%以上出发,提出采用复合萃取法分离乙酸乙酯和水,从乙酸乙酯、水与溶剂分子之间存在的诱导力、静电力、色散力及氢键出发,对12类溶剂进行分析和对比,提出可选用多元醇、水、羧酸、胺类、酮作为萃取溶剂;采用单级汽液平衡釜研究各种溶剂对乙酸乙酯和水相对挥发度的影响,经测定以甘油为溶剂,乙酸乙酯与水的相对挥发度达8.9以上;研究在不同温度、溶液比的条件下,相对挥发度的变化情况,为进一步实验研究提供依据.
Abstract:
The com po site ex tractive separation ( d ifferen t ex tractive agents at different po sitions) o f ethy l acetate and w ate r is propo sed fo r the a im s o f simp lify ing production techno logy, reduc ing energy consum ption agents and once ra i-sing the concentration of ethy l ace tate to over 99. 5%. A ll k inds o f agents com posed o f sing le, bina ry, ternary com po-nen ts a re summ arized. Upon the sho rtag es of system atic researches and com parisons of ex tractive agen ts, in the paper ex tractive agents a re c lassified into tw e lve types from the interactions betw een m o lecules, e lectrostatic fo rce, disper-sion force, hydrog en bond, et al. The e ffects of a ll k inds of extractive agents on separation of e thy l aceta te and w ater system are ana ly zed, and po lybasic a lcoho,l wa ter, carboxy lic ac id, am ides and ketone are cho sen as separation a-g ents for ethy l aceta te and w ater system. A ffec tion of temperature and so lvent ratio on re lative vo latility is studied, w ith m easured data from the checked po t, com b ined w ith other influenc ing factors, g lycerol is se lected as extrac tive so lvent fo r ethy l acetate /w ate r system.
