This work tries to explore the relation between molecular structures of ionic liquids (ILs) as entrainers and separation performance on ethyl acetate (1) and ethanol (2). The vapor-liquid equilibrium (VLE) data have been measured for ethyl acetate (1) + ethanol (2) containing ILs at 101.32 kPa. The ionic liquids investigated were 1-butyl-3-methylimidazolium tetrafluoroborate (that has been studied in our previous work. All the ILs could give rise to the salting-out effect. It was found that, at low IL concentration, the separation ability of ILs is in the order-, while at high IL concentration (x 3 ) 0.10-0.30) the separation ability of ILs is in the order]due to the difference of polarity of the three ILs and demixing effect. [EMIM] + [triflate]was included as entrainer and compared with the tetrafluoroboratebased ILs. The measured ternary data were correlated using the NRTL model.

Chinese cabbage (Brassica rapa ssp. chinensis) is an economically and agriculturally significant vegetable crop and is extensively cultivated throughout the world. Heat stress disturbs cellular homeostasis and causes visible growth inhibition of shoots and roots, severe retardation in growth and development, and even death. However, there are few studies on the transcriptome profiling of heat stress in non-heading Chinese cabbage. In this study, we investigated the transcript profiles of non-heading Chinese cabbage from heat-sensitive and heat-tolerant varieties “GHA” and “XK,” respectively, in response to high temperature using RNA sequencing (RNA seq). Approximately 625 genes were differentially expressed between the two varieties. The responsive genes can be divided into three phases along with the time of heat treatment: response to stimulus, programmed cell death and ribosome biogenesis. Differentially expressed genes (DEGs) were identified in the two varieties, including transcription factors (TFs), kinases/phosphatases, genes related to photosynthesis and effectors of homeostasis. Many TFs were involved in the heat stress response of Chinese cabbage, including NAC069 TF which was up-regulated at all the heat treatment stages. And their expression levels were also validated by quantitative real-time-PCR (qRT-PCR). These candidate genes will provide genetic resources for further improving the heat-tolerant characteristics in non-heading Chinese cabbage.

Isobaric vapor-liquid equilibrium (VLE) data for {propan-2-ol (1) + water (2) + 1-butyl-3-methylimidazolium tetrafluoroborate(3)} where 3 is an ionic liquid ([BMIM] + [BF 4 ] -) at atmospheric pressure (101.32 kPa) were measured with a modified Othmer still. The results showed that the ionic liquid studied can transfer the azeotropic point and eliminate the azeotropic phenomena when its concentration is up to x 3 ) 0.20. This means that [BMIM] + [BF 4 ]can be used as a promising entrainer in the application of extractive distillation. However, the comparison of the salting-out effect of [BMIM] + [BF 4 ]with that of 1-ethyl-3methylimidazolium tetrafluoroborate ([EMIM] + [BF 4 ] -) was conducted. The measured ternary data were correlated using the NRTL equation.
