Shape-selective amination of EO over HZSM-5 for MEA and DEA

Feng, Ruming,Wang, Deju,Liu, Zhongneng,Xie, Zaiku

, p. 1220 - 1223 (2010)

Shape-selective amination of ethylene oxide over HZSM-5 was thoroughly investigated. TPD, FTIR and catalytic performance showed that HZSM-5 was more active than the sodium form. Relative selectivity of product was mainly controlled by the crystal size of ZSM-5. Surface modification such as silyation was effective for enhancing the shape selectivity. Among the catalysts tested in this study, HZSM-5 with SiO2/Al2O3 ratio being 76.7 exhibited the best performance. At 353 K and total pressure of 8.0 MPa the total selectivity of MEA and DEA was 97.6%, the yield reached 96.6%, the best performance achieved so far among EO amination.

AFFINITIES OF CROWN ETHERS, GLYMES, AND POLYAMINES FOR ALKALI PICRATES IN TOLUENE. APPLICATION OF POLYMER-SUPPORTED LINEAR POLYETHERS.

Xu,Smid

, p. 3790 - 3796 (1984)

This work reports the measurements of K values for polyamines, glymes, a few glycols (including that of a long-chain polyethylene glycol, carbowax 6000), and some frequently used cation-binding ligands as complexers of lithium or sodium picrate in toluene as solvent. K values for different resins obtained with the same soluble ligand provide a comparison of the effectiveness of these resins in binding ionic solutes.

Electrocatalytic reduction of low concentration CO2

Kumagai, Hiromu,Nishikawa, Tetsuya,Koizumi, Hiroki,Yatsu, Taiki,Sahara, Go,Yamazaki, Yasuomi,Tamaki, Yusuke,Ishitani, Osamu

, p. 1597 - 1606 (2019)

Utilization of low concentration CO2 contained in the exhaust gases from various industries and thermal power stations without the need for energy-consuming concentration processes should be an important technology for solving global warming and the shortage of fossil resources. Here we report the direct electrocatalytic reduction of low concentration CO2 by a Re(i)-complex catalyst that possesses CO2-capturing ability in the presence of triethanolamine. The reaction rate and faradaic efficiency of CO2 reduction were almost the same when using Ar gas containing 10% CO2 or when using pure CO2 gas, and the selectivity of CO formation was very high (98% at 10% CO2). At a concentration of 1% CO2, the Re(i) complex still behaved as a good electrocatalyst; 94% selectivity of CO formation and 85% faradaic efficiency were achieved, and the rate of CO formation was 67% compared to that when using pure CO2 gas. The electrocatalysis was due to the efficient insertion of CO2 into the Re(i)-O bond in fac-[Re(dmb)(CO)3{OC2H4N(C2H4OH)2}] (dmb = 4,4′-dimethyl-2,2′-bipyridine).

A REDOX COMBINED PHOTOCATALYSIS: NEW METHOD OF N-ALKYLATION OF AMMONIA BY TiO2/Pt SUSPENDED IN ALCOHOLS

Ohtani, Bunsho,Osaki, Haruyoshi,Nishimoto, Sei-ichi,Kagiya, Tsutomu

, p. 2019 - 2022 (1986)

Ammonia was efficiently N-alkylated into tertiary amines by room-temperature photoirradiation at >300 nm in the presence of platinized titanium dioxide suspended in alcohols, such as methanol, ethanol, and ethylene glycol.A couple of processes, photocatalytic dehydrogenation of alcohols and thermal hydrogenation of an imine intermediate, account for the ammonia N-alkylation.

Development of 2,2′-iminodiethanol selective production process using shape-selective pentasil-type zeolite catalyst

Tsuneki, Hideaki,Kirishiki, Masaru,Oku, Tomoharu

, p. 1075 - 1090 (2007)

Ethanolamines are produced on an industrial scale exclusively by the reaction of ethylene oxide with an aqueous solution of ammonia. The reaction is a typical consecutive reaction with three steps; therefore, it is difficult to produce 2,2′-iminodiethanol (the second product of the reaction) with high selectivity by conventional means. We developed a catalytic 2,2′-iminodiethanol selective production process using a pentasil-type zeolite catalyst modified with rare earth elements. This highly active catalyst was able to recognize the difference at molecular level between 2,2′-iminodiethanol and 2,2′,2″-nitrilotriethanol; 2,2′,2″-nitrilotriethanol was not formed in its micropore. We also succeeded in producing a binderless molded zeolite catalyst that does not form problematic impurities and that has a shape suitable for a fixed-bed reactor. The problem of activity deterioration was overcome by developing a regeneration process using high-temperature and high-density ammonia gas as a rinse medium.

Organoboranes. LI. Convenient procedures for the recovery of pinanediol in asymmetric synthesis via one-carbon homologation of boronic esters

Brown, Herbert C.,Rangaishenvi, Milind V.

, p. 15 - 30 (1988)

Matteson's asymmetric synthesis via a one-carbon homologation of the pinanediol boronic esters with (dichloromethyl)litihium at -100 deg C results in the insertion of a chloromethyl group into the carbon-carbon bond with > 99percent diastereoselectivity.This procedure makes possible the asymmetric synthesis of the chiral moiety, RR'CH*B(OR'')2, providing an alternative route to chiral hydroboration for these valuable chiral intermediates.Unfortunately, this method suffers from the remarkable difficulty encountered in the recovery of the pinanediol chiral auxiliary, making this asymmetric synthesis impractical.Fortunately, a systematic study of the problem has uncovered convenient procedures for the recovery of pinanediol from pianendiol boronate esters

Deoxygenation of amine oxides by in situ-generated formic pivalic anhydride

Rosenau, Thomas,Potthast, Antje,Ebner, Gerald,Kosma, Paul

, p. 623 - 625 (1999)

A novel method for the highly efficient deoxygenation of tertiary and aromatic amine oxides is described. The initial step of the reaction is the O-formylation of the amine oxide by formic pivalic anhydride which is produced in situ. The approach has the advantage of superior convenience in preparation and work-up since all products of the reaction are solids or gases rendering the amine very readily separable.

Boronic Ester Based Vitrimers with Enhanced Stability via Internal Boron-Nitrogen Coordination

Zhang, Xiaoting,Wang, Shujuan,Jiang, Zikang,Li, Yu,Jing, Xinli

supporting information, p. 21852 - 21860 (2021/01/11)

Boron-containing polymers have many applications resulting from their prominent properties. Organoboron species with reversible B-O bonds have been successfully employed for the fabrication of various self-healing/healable and reprocessable polymers. However, the application of the polymers containing boronic ester or boroxine linkages is limited because of their instability to water. Herein, we report the hydrolytic stability and dynamic covalent chemistry of the nitrogen-coordinating cyclic boronic diester (NCB) linkages, and a new class of vitrimers based on NCB linkages is developed through the chemical reactions of reactive hydrogen with isocyanate. Thermodynamic and kinetic studies demonstrated that NCB linkages exhibit enhanced water and heat resistance, whereas the exchange reactions between NCB linkages can take place upon heating without any catalyst. The model compounds of NCBC-X1 and NCBC-X2 containing a urethane group and urea group, respectively, also showed higher hydrolytic stability compared to that of conventional boronic esters. Polyurethane vitrimers and poly(urea-urethane) vitrimers based on NCB linkages exhibited excellent solvent resistance and mechanical properties like general thermosets, which can be repaired, reprocessed, and recycled via the transesterification of NCB linkages upon heating. Especially, vitrimers based on NCB linkages presented improved stability to water and heat compared to those through conventional boronic esters because of the existence of N → B internal coordination. We anticipate that this work will provide a new strategy for designing the next generation of sustainable materials.
