WitrynaSolvothermal synthesized CeO2 nanoflakes were plasma treated under different atmospheres (combination of Ar, H2, O2 and NH3), and further used for imine synthesis. The plasma processing can improve the amount of surface oxygen vacancies, Ce3+ ratio, and the peroxy anions O22− ratio. All the three parameters … Witryna29 kwi 2024 · When the temperature is only 110 °C, the yield of the imine synthesized by benzyl alcohol and aniline was 91%, while the yield of the imine at the reaction temperature of 80 °C was only 68% (Table 1, entries 2 and 3). ... The above results prove that Cu-MOF/Au–Pd is the most promising catalyst in imine synthesis.
WitrynaPolyaniline was first known in 1835 as ‘aniline black’, a term used for any product obtained by the oxidation of aniline [1]. At the beginning of the 20th century, Green and co-workers [2, 3] proposed a linear octameric structure of the quinone-imine type in the para position, for the product obtained by the chemical oxidation of aniline.
