MIBK分离技术？ 先用精馏塔蒸一下，看一下塔顶塔底出料浓度如何。 关于这个体系的汽液平衡数据很少。没法发附件，先把摘要寄给你。 另一建议，用亲水性渗透汽化，先分出大部分水和少量丁醇，再用精馏塔分mibk 和 xylene。 我是做亲油渗透汽化的。 清华[wiki]化工[/wiki]系可以做亲水性渗透汽化。 vapor-liquid equilibrium of the systems of methyl isobutyl ketone with chlorobenzene, o-dichlorobenzene, bromobenzene and p-xylene。 fluid phase equilibria (1988), 40(3), 311-318. abstract boiling temps. were measured for 4 binary systems of mibk with phcl, o-dichlorobenzene, phbr, and p-xylene at 300, 500, and 700 torr. the data were correlated by using the wilson equation. vapor-liquid equilibriums in the ternary systems tert-butyl alcohol-diethyl ketone-methyl isobutyl ketone and diethyl ketone-methyl isobutyl ketone-n-butyl alcohol and their binaries. journal of chemical and engineering data (1978), 23(4), 293-8. abstract new data on the vapor-liq. equil. of the ternary systems tert-buoh-di-et ketone-me iso-bu ketone and di-et ketone-me iso-bu ketone-buoh and their binaries were obtained at 760 torr. the activity coeffs. were satisfactorily correlated according to the redlich-kister equation and the behavior of the ternary mixts. were predictable from the binary data. b.ps. of the mixts. were correlated well by an empirical correlation and were predictable to within a mean error of 0.07-0.7%. the ternary systems do not exhibit azeotropic behavior. the binary system me iso-bu ketone-buoh forms an azeotrope that boils at 113.28 ° and contains 63.3 mol % me iso-bu ketone. vapor-liquid equilibrium of system methyl isobutylketone-butyl alcohol. journal of chemical and engineering data (1972), 17(1), 98-9. abstract vapor-liq. equil. data for the system me iso-bu ketone-buoh were detd. at 80, 90, and 100° and 760 mm hg total pressure from ebulliometric measurements obtained by using a swietoslawski-type ebulliometer. vapor compns. were obtained by numerical integration, and the vapor-liq. equil. data were then analyzed in terms of the 3 const. redlich-kister equations.查看更多
