New research progress on 28053-08-9 in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. In an article, author is Tang, John, once mentioned the application of 28053-08-9, Synthetic Route of 28053-08-9, Name is Disodium UDP-glucose, molecular formula is C15H22N2Na2O17P2, molecular weight is 610.27, MDL number is MFCD00077895, category is dioxole. Now introduce a scientific discovery about this category.
Dehydration of aprotic solvents, frequently needed in pharmaceutical processing, can be implemented easily by vacuum-based pervaporation employing a novel perfluoropolymer-based membrane: perfluoro-2,2-dimethyl-1,1,3-dioxole copolymerized with tetrafluoroethylene (PDD-TFE). Possessing one of the highest fractional free volumes, this polymer is resistant to most solvents including N,N-dimethyl formamide (DMF), N,N-dimethylsulfoxide (DMSO), and N,N-dimethylacetamide (DMAc). Results were obtained using a 25 mu m thick dense polymeric membrane supported by a porous polytetrafluoroethylene (PTFE) sheet. Maximum water flux values found for a 90 wt% aprotic solvent feed were as follows: 77 g/(m(2) h) for DMF-water mixture at 50 degrees C; 9.8 g/(m(2) h) for DMSO-water mixture at 30 degrees C; 9 g/(m(2) h) for DMAc-water mixture at 50 degrees C. Excellent pervaporation separation factors for water over these aprotic solvents were obtained for mixtures containing 1, 5 and 10 wt% water in the temperature range 30-60 degrees C. The separation factors varied between 1000 and 12,000 depending on the water content, temperature and the solvent species. Such highly selective water removal in pervaporation has been achieved earlier in dehydration of ethanol by NaA zeolite membranes which however achieve an order of magnitude lower selectivity in for example, DMF-water system.
