摘 要:A novel technique combining photoelectronic microscopy and computer imaging tracing was used to investigate the synthesis of thioether(2-[3-methyl-4-(2,2,2-trifluoro-ethoxy)-pyridine-2-(methylsulfanyl)]-1H-benzoimidazole),which is an intermediate for *** in sub-microcosmic surroundings was realized to study interfacial *** reaction kinetics study by a visualization technique was carried out in a mini-reactor,and the concentration-gray scale standard curves for thioether were obtained by analyzing the gray scales of digital *** on the concentration-gray scale standard curves,the reactant concentrations at different times were calculated,and the reaction kinetics curve and reaction rate equation were *** the total mass-transfer resistance from bulk phase to interface of sodium imidazole and bromopyridine was ***-liquid interface of synthesizing thioether was observed and its mass transfer mechanism was discussed.
