Ethylene carbonate and thiocarbonate partially oriented in the nematic phase of N-( p-ethoxy benzylidene)- p-n-butylaniline have been studied by NMR. The absolute signs of the dipolar couplings in both are positive for the geminal and cis vicinal couplings and negative for the trans vicinal ...

Ethylene carbonate can be formed from ethylene glycol and CO2 over CeO2-ZrO2 catalysts. The activity of ethylene carbonate formation was much dependent on the catalyst composition and calcination temperature, and it is found that CeO2-ZrO2 (Ce/(Ce+Zr)=0.33) calcined at high temperature (1273 ...

The EC/CL copolymers were obtained in a higher carbonate content (up to ca. 30 mol%) and in a better yield compared with EC/VL copolymers. The 1H NMR and thermal analyses revealed that these copolymers exhibit random arrangement. The enzymatic degradations of EC/lactone copolymers were ...
1H-NMR spectra (a–c) and concentrations (d–f) of n-propanol (a, d), ethanol (b, e) and acetate (c, f) of the anolyte after electro-oxidation control experiments conducted under reaction conditions similar to that for CO2/CO electrolysis. The cathode and anode catalysts are Cu nanopar...
solution in ethylene carbonate with different lithium perchlorate concentrations (from the strongest dilution 0.01 M to 3 M). Agreement with the experimental NMR spectra is achieved. Calibration molecular structures for calculating the chemical shifts of H, Li, C, O, and Cl nuclei are proposed....
