Nitrobenzene liquid phase catalytic oxidation reaction

/ L. Hydrogenation reaction rate in hydrogenation reaction is complete , said the countdown time . 2.2.4 apply the test in order to reduce the cost of the catalyst , catalyst recovery should be considered to apply , but each time there is a certain loss of recovery of applied , and some may be poisoning the active site and thus should be supplemented with some fresh pd / c catalyst Table 3 Catalyst number applying experimental experimental catalyst / g of aniline yield of hydrogenation rate of × 10. / Rain 0.0599.911.0 an original experiment to apply * bo. 012599.911.1 second apply * bo. O12599.811.0 three Triple use fill 0. O12599.910.5 four apply fill 0. O12599.9l1.0 reaction temperature is 80 ℃, 0.6MPa hydrogen pressure Table 3 shows , each applied to the original firefly additional 1 / 4, and hydrogen production rate from the rate of aniline point of view, the catalyst can also continue to apply the go . 3 Conclusion a Catalytic Hydrogenation to Aniline in pd / c catalyst , the reaction experienced by the nitrobenzene (NB) oxide azobenzene (AZXB) ~ azobenzene (AzB) an aniline (A), Process, the initial reaction kinetics of a reaction, including the technology for 34.92kJ. toolb optimal reaction conditions pd / e catalyst 0.5g / L (NB),[link widoczny dla zalogowanych], reaction temperature 80 ~ C, hydrogen pressure 0.6MPac use 0.8pd / c catalyst , continuous applied four times the yield rate and non- hydrogenated Affected.
