The invention relates to a process for preparing purified, virtually odourless, solid benzoic acid obtained from toluene by oxidation with a gas containing molecular oxygen, by means of a treatment using an inert gas or gas mixture, wherein the benzoic acid to be purified is supplied in a ...
Hebei Smart Benzoic Acid Our Benzoic Acid is produced by oxidation of toluene with an oxygen containing gas. We put toluene and Cobalt naphtenate into oxygenation tower at 165°C-180°C, then suppress into distillation still, boil up non-reacted toluene, we can get crude Benzoic Acid. After...
As mentioned previously, toluene, benzyl alcohol and benzaldehyde are converted to benzoic acid. Currently, only one benzoic acid metabolic pathway has been observed in fungi and was reported inA. niger, A. nidulans, Cochliobolus lunatus, P. chrysosporiumandRhodotorula minuta(Boschlooet al., 1990; ...
The industrial benzoic acid is mainly by toluene liquid phase air oxidation preparation. The process was with cobalt naphthenate as catalyst, in response to temperature is 140-160 ℃ and operating pressure is 0.2-0.3MPa and response generation benzoic acid. Reaction after steaming to toluene, and ...
