Abstract ：
Incorporation of ionic liquids into metal-organic frameworks (MOFs) offers a new platform to construct heterogeneous bifunctional catalytic systems for the chemical capture and conversion of CO2 with epoxides. Herein, an imidazolium-based ionic liquid decorated UiO-66 type MOF (P3[BCMIm]Br@UiO-66) was successfully constructed via solvothermal assembly of the carboxyl-functionalized imidazolium ionic liquid ligand, terephthalic acid ligand and Zr(iv) ions. It exhibits the highest catalytic activity upon the cycloaddition of CO2 (98.2% conversion of propylene oxide and 99% selectivity to propylene carbonate) under optimized conditions (2.2 Mpa CO2, 1.0 wt%, 110 degrees C, reaction time 2 h). Notably, P3[BCMIm]Br@UiO-66 outperformed the original UiO-66 materials and [BCMIm]Br. P3[BCMIm]Br@UiO-66 retained its good catalytic performance for up to five recycling runs with only a little loss in catalytic activity. Furthermore, several additional coupling reactions were investigated with other epoxides as substrates.

Abstract ：
Cylcohexanol is an essential bulk chemical that can be produced via cyclohexene hydration, a liquidliquid two-phase reaction that is limited by the low reaction rate and the equilibrium conversion. Adding an appropriate solvent is the most promising method to break through these limitations. However, in previous works the solvent was almost blindly selected without a global consideration. In this work, a rational multiscale method is proposed for the effective selection of an economical and sustainable solvent for the direct hydration of cyclohexene. At the molecular scale, liquid-liquid phase equilibrium was estimated using group contribution methods to rapidly screen the potential solvent candidates from a range of organics, based on the partition coefficient. At the reactor scale, the candidates were experimentally investigated to pick out the solvents that could significantly improve the conversion, without introducing side reactions or deactivating the catalyst. At the process scale, the total annual cost (TAC), CO2 emission, and other metrics were calculated to evaluate the eco-efficiency of all solvents. Using this multi-scale method, acetophenone was selected as an eco-efficient solvent from over 100 organics, resulting in the reduction of TAC by 8 % and CO2 emission by 17 % in the production process. Using acetophenone also led to the increase of cyclohexanol yield from 12.3 % to 27.6 % without the occurrence of side reactions and catalyst deactivation. & COPY; 2023 The Author(s).

Abstract ：
Achieving a balance between flame retardancy and overall performance in epoxy resin (EP) continues to be a significant challenge. In this study, a new multi-DOPO-based reactive flame retardant (DZH) was synthesized successfully using a simple one-pot method and employed as a co-curing agent with DDM. The results indicated that the inclusion of DZH decreased the activation energy of the curing reaction system. Furthermore, the presence of DZH, with its remarkable charring ability, enhanced the formation of char residues under high temperature conditions. Notably, the flame retardancy and mechanical properties of the EP/DZH system were significantly enhanced at certain additions. When added at only 5 wt% (phosphorus content: 0.525 wt%), the LOI value of the EP/DZH-5 increased from 24.4 % to 35.3 % for the EP matrix and achieved a V-0 rating in accordance with UL-94. Meanwhile, EP/DZH-5 exhibited a reduction of 44.1 % in pHRR and 24.3 % in SPR. The superior flame retardancy of the EP/DZH system was attributed to the dual flame-retardant mechanism exhibited in both the gaseous and condensed phases. In addition, the abundant presence of rigid phosphaphenanthrene groups and 7C-7C interactions between benzene rings led to an improvement in the tensile strength and tensile modulus, which rose to 91.0 MPa and 1.76 GPa, respectively, from 79.5 MPa and 1.26 GPa of EP in the case of EP/DZH-3. The utilization of this flame retardant, based on multi-DOPO, offers a promising approach for the development of high-performance epoxy resins.

Abstract ：
Droplet breakup in microconstrictions is an important phenomenon in industrial applications. This work aimed to investigate the droplet breakup in the square microchannel with a short square constriction to generate the slug flow, which drew little attention before. Mechanism analysis indicated that this breakup process included the shear-force-dominated, squeezing-force-dominated, and pinch-off stages. Nonuniform daughter droplets were generated in the constriction with their interface restricted in the horizontal and perpendicular directions by the microchannel walls. The average relative deviation of the daughter droplet size was <30%, much lower than that for the breakup with the daughter droplet restricted only in one direction. An empirical equation with a deviation of <20% was provided to show the dependence of the daughter droplet size on the operation conditions. The comparison results suggested that the different restriction effects of microchannel wall on daughter droplets led to the different breakup mechanisms in different constrictions.

Abstract ：
Economically separating 1-propanol (NPA) from water is an emergent issue for producing pharmaceutical intermediates such as n-propyl acetate, n-propylamine and so on. In this work, fourionic liquids (ILs) 1ethyl-3-methylimidazolium thiocyanate ([EMIM][SCN]), 1-butyl-3methylimidazolium tetrafluoroborate ([BMIM][BF4]), 1,3-dimethylimidazolium methylsulfate ([MMIM][MS]), 1,3-dimethylimidazolium dimethylphosphate ([MMIM][DMP]) were introduced as potential entrainers for separating NPA-water azeotropic mixture. The results show that [MMIM][MS] is the most suitable entrainer compared with other ILs from the analysis of vapor-liquid equilibrium and relative volatilities. The extractive distillation process with the entrainer regeneration system of flash tank and stripper was employed and optimized by the two-step optimization method. The results show that total annual cost and energy consumption per product flow rate were reduced by 39.79% and 60.47% compared with literature. In addition, the efficiency indicator of extractive section, efficiency indicator of per tray in extractive section, carbon dioxide emissions were also selected as the evaluation index for selection of operating parameters and calculated for different cases. The CO2 emissions of the optimal design can be reduced by 60.98% from environmental aspect. (c) 2022 The Chemical Industry and Engineering Society of China, and Chemical Industry Press Co., Ltd.
