Butt, Tahreem Hafeez;Tamime, Rahma;Budd, Peter M.;Harrison, Wayne J.;Shamair, Zufishan;Khan, Asim Laeeq research published 《 Enhancing the organophilic separations with mixed matrix membranes of PIM-1 and bimetallic Zn/Co-ZIF filler》, the research content is summarized as follows. Novel mixed matrix membranes (MMMs) were fabricated by incorporating bimetallic Zn/Co-ZIF nanoparticles into the prototypical polymer of intrinsic microporosity (PIM-1). The morphol. and structural characteristics of Zn/Co-ZIF and ZIF-8 were analyzed with XRD, FTIR, BET and SEM. The characterization results showed that the Zn/Co-ZIF is isostructural to ZIF-8 occupying the same crystallog. sites, however, Zn/Co-ZIF has smaller BET surface area and lower pore volume than ZIF-8. The SEM images of fabricated MMMs demonstrated good dispersion and interaction of the filler in the polymer matrix, even at high loadings. The addition of hydrophobic nanoparticles enhanced the hydrophobicity of the MMMs, and relatively more for the Zn/Co-ZIF/PIM. The MMMs were analyzed for their separation performance of two binary mixtures made of ethanol/water and butanol/water comprising 5 wt% alc., via pervaporation. Flux and separation factor of both alcs. increased with filler loadings in both ZIF-8/PIM-1 and Zn/Co-ZIF/PIM-1 membranes, showing an anti-tradeoff effect which is more significant in Zn/Co-ZIF/PIM-1 membranes. Zn/Co-ZIF/PIM-20 wt% membranes showed 129% higher separation in comparison with pristine PIM-1 membranes. Moreover, not only did the Zn/Co-ZIF/PIM-1 membranes show a higher separation factor, but they also had a higher rate of increase with increased loadings, which was quasi-constant for ZIF-8/PIM-1 membranes. ZIF-8/PIM-1 at filler loading of 20 wt% showed the highest normalized flux of 139 kg.μm.m-2.h-1.

Caliskan, Esra;Shishatskiy, Sergey;Neumann, Silvio;Abetz, Volker;Filiz, Volkan research published 《 Investigation of the Side Chain Effect on Gas and Water Vapor Transport Properties of Anthracene-Maleimide Based Polymers of Intrinsic Microporosity》, the research content is summarized as follows. In the present work, a set of anthracene maleimide monomers with different aliphatic side groups obtained by Diels Alder reactions were used as precursors for a series of polymers of intrinsic microporosity (PIM) based homo- and copolymers that were successfully synthesized and characterized. Polymers with different sizes and shapes of aliphatic side groups were characterized by size-exclusion chromatog. (SEC), (NMR) 1H-NMR, thermogravimetric (TG) anal. coupled with Fourier-Transform-IR (FTIR) spectroscopy (TG-FTIR) and d. measurements. The TG-FTIR measurement of the monomer-containing Me side group revealed that the maleimide group decomposes prior to the anthracene backbone. Thermal treatment of homopolymer methyl-100 thick film was conducted to establish retro-Diels Alder rearrangement of the homopolymer. Gas and water vapor transport properties of homopolymers and copolymers were investigated by time-lag measurements. Homopolymers with bulky side groups (i-propyl-100 and t-butyl-100) experienced a strong impact of these side groups in fractional free volume (FFV) and penetrant permeability, compared to the homopolymers with linear alkyl side chains. The effect of anthracene maleimide derivatives with a variety of aliphatic side groups on water vapor transport is discussed. The maleimide moiety increased the water affinity of the homopolymers. Phenyl-100 exhibited a high water solubility, which is related to a higher amount of aromatic rings in the polymer. Copolymers (methyl-50 and t-butyl-50) showed higher CO2 and CH4 permeability compared to PIM-1. In summary, the introduction of bulky substituents increased free volume and permeability while the maleimide moiety enhanced the water vapor affinity of the polymers.

Carja, Ionela-Daniela;Tavares, Sergio Rodrigues;Shekhah, Osama;Ozcan, Aydin;Semino, Rocio;Kale, Vinayak S.;Eddaoudi, Mohamed;Maurin, Guillaume research published 《 Insights into the Enhancement of MOF/Polymer Adhesion in Mixed-Matrix Membranes via Polymer Functionalization》, the research content is summarized as follows. MOF-based mixed-matrix membranes (MMMs) prepared using standard routes often exhibit poor adhesion between polymers and MOFs. Herein, we report an unprecedented systematic exploration on polymer functionalization as the key to achieving defect-free MMMs. As a case study, we explored computationally MMMs based on the combination of the prototypical UiO-66(Zr) MOF with polymer of intrinsic porosity-1 (PIM-1) functionalized with various groups including amidoxime, tetrazole, and N-((2-ethanolamino)ethyl)carboxamide. Distinctly, the amidoxime-derivative PIM-1/UiO-66(Zr) MMM was predicted to express the desired enhanced MOF/polymer interfacial interactions and thus subsequently prepared and evaluated exptl. Prominently, high-resolution transmission electron microscopy confirmed optimal adhesion between the two components in contrast to the nanometer-sized voids/defects shown by the pristine PIM-1/UiO-66(Zr) MMM. Notably, single-gas permeation measurements further corroborated the need of optimal MOF/polymer adhesion in order to effectively enable the MOF to play a role in the gas transport of the resulting MMM.

Chang, Siqi;Xie, Wei;Yao, Chan;Xu, Guangjuan;Zhang, Shuran;Xu, Yanhong research published 《 Preparation of covalent triazine frameworks with multiactive sites for efficient and reversible iodine capture》, the research content is summarized as follows. Covalent triazine skeletons (CTFs) are long-chain polymers with rigid hydrophobic aromatic skeletons and polar functional groups. Here, we selected three monomers to explore a series of stable CTFs (FCTFs, NCTFs, ClCTFs) with multiple active sites at 350 and 400°C resp., which can act as a porous platform for effective and reversible iodine capture. The iodine adsorption capacities of FCTF@350, NCTF@350, ClCTF@350, FCTF@400, NCTF@400 and ClCTF@400 are 285, 232, 231, 382, 372 and 340 wt%, resp. Among them, the iodine capture capacities of FCTFs and NCTFs are higher than those of ClCTFs, which suggested that the introduction of electron-rich F and pyridine N groups can indeed improve the iodine adsorption capacity of the polymers. In addition, at 50 bar and 323 K, the CO2 capture capacity of FCTF@350, NCTF@350, ClCTF@350, FCTF@400, NCTF@400 and ClCTF@400 are 631.6, 539.2, 496.6, 876.6, 783.3, and 695.4 mg g-1, resp. This shows that polymers have good applications in CO2 capture.

Phys. aging represents one of the major obstacles towards adoption of polymer of intrinsic microporosity (PIM) membranes for gas separation applications. In this work, mixed matrix membranes (MMMs) of 2D boron nitride nanosheets (BNNS) and PIM-1 were prepared and applied in the separation of a CO2/CH4 (1:1, v:v) binary gas mixture The membranes were tested over a period of more than one year to evaluate their anti-aging properties as compared to neat PIM-1. The results show that introducing BNNS into PIM-1 leads to a significant reduction in the phys. aging of PIM-1, as demonstrated by the values of reduction in CO2 permeability after 414 days (22% for the MMMs as compared to 58% for neat PIM-1). This work paves the way to using PIM-based membranes in industry.

24-Sep News Application of 1835-49-0

At the same time, in my other blogs, there are other synthetic methods of this type of compound, Tetrafluoroterephthalonitrile, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 1835-49-0, name is Tetrafluoroterephthalonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1835-49-0, name: Tetrafluoroterephthalonitrile

[Comparative Example 1]; The same operations as in Example 1 were carried out, except that the amount of the catalyst used was changed from 0.25 g to 0.05 g on a dry weight basis. After a lapse of 7.0 hours, absorption of hydrogen ceased. The quantity of hydrogen absorbed was 83% of the theoretical quantity of hydrogen absorbed.

Related Products of 1835-49-0, A common heterocyclic compound, 1835-49-0, name is Tetrafluoroterephthalonitrile, molecular formula is C8F4N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Water-wet tetrafluoroterephthalonitrile 56. 69 G (10% water content, 98% pure, 50.0 g in terms of tetrafluoroterephthalonitrile), water-wet 5% Pd/C 1.18 g (58% water content, 0.5 g in terms of Pd), and toluene 200.0 g were introduced into a 500 ml three-necked glass flask equipped with a stirrer, a thermometer, a Claisen tube and a cooling tube. The contents were heated to distill away toluene and water together in an amount of 187.5 g. After cooling, toluene 187.5 g was added and the water content was measured to be 150 ppm. The resultant reaction solution was introduced into a 500 ml stainless steel autoclave (NU-4 model produced by Nitto Koatu Co., Ltd. ), and further Zeolite 5A powder 45 g (Molecular Sieve 5A produced by Union Showa K. K. ) was added thereto. Then the autoclave was purged with nitrogen. THEREAFTER THE CONTENTS WERE HEATED TO 160C under stirring, and hydrogen pressurized at a pressure higher than that in the autoclave at the above temperature by 0.1 MPa was supplied to initiate hydrogenolysis. The rate of hydrogen absorption lowered in approximately 5 hours and 30 minutes of reaction time, and the supply of hydrogen was terminated to end the reaction. The hydrogen absorption was 116 MOL% (based on the mol of tetrafluoroterephthalonitrile under standard conditions). Cooled to room temperature, the reaction slurry was filtered, and the filtrate was analyzed with the gas chromatography analyzer. The analysis gave a conversion of 97. 8% and a reaction yield of 84.4 % (product: 2,3, 5,6-tetrafluorobenzonitrile). Example 5 Reaction was conducted basically in the same manner as in Example 4 except that the amount of 5% Pd/C was altered to 2.38 g (58% water content, 1.0 g in terms of Pd) and that the amount of the Zeolite 5A powder was altered to 37.5 g (Molecular Sieve 5A produced by Union Showa K. K. ). The results were that the hydrogenolysis reaction was completed in 5 hours and 30 minutes and the hydrogen absorption was 114%. The analysis gave a conversion of 98. 2% and a reaction yield of 87. 5% (product: 2,3, 5, 6-tetrafluorobenzonitrile).Example 6 Reaction was conducted basically in the same manner as in Example 4 except that the amount of 5% Pd/C was altered to 1.43 g (58% water content, 0.6 g in terms of Pd).
