| Abstract: | To explore the optimal condition for synthetising N,N’-diphenylformamidine from formic acid and aniline by catalyzed dehydration,the factors for effecting synthesis process were discussed by single factor tests.It is resulted that best conditions was showed as follows:using 30 mL dimethylbenzene as dehydrator,formic acid 4.6 g(0.1 mol),aniline 32.55 g(0.35 mol),cast iron 1 g,borax 0.3 g,reaction temperature 150 ℃,reaction time 6 h.The total yield was 91.5 %,The structures were characterized by 1H NMR and 13C NMR spectra.It is conclused that synthetic process is advantages of high yield,simple operation and safety and is possible of industrialized production. |
