(1) an oxidizing agent. Consumption of acetic acid oxidation of the oxidizing agent may be air or pure oxygen. Often used industrially pure oxygen as the oxidant, the reaction of oxygen can be fully absorbed, high efficiency, and acetaldehyde is not a lot of inert gas away. (2) oxygen diffusion and absorption. Diffusion and absorption of oxygen has a great influence on the oxidation process, it oxygenation speed. Oxygenation faster, the larger the gas-liquid contact surface, the higher the oxygen absorption rate. However, when more than a certain limit, due to the significant excess oxygen, the oxygen absorption rate but will reduce, or even take away a lot of acetaldehyde, consumption of acetic acid. In order to accelerate the rate of oxygen diffusion and absorption, the oxygen can be, middle and lower passages through into the reactor, and set the oxygen sparger, and uniformly dispersed into bubbles of suitable size. (3) the reaction temperature. Elevated temperature favors the formation and consumption of acetic acid peroxide decomposition, but high temperatures can cause side effects accelerated glacial acetic acid and volatile food poured into the upper part of the gas-phase oxidation tower space, and the solubility of oxygen but with temperature increased and decreased, so that the oxygen concentration in the gas phase and the consumption of acetic acid is increased, the formation of explosive hazard; temperature is too low (<40 ℃), the oxidation rate is decreased slow decomposition peroxide consumption of acetic acid, resulting in the accumulation of peroxide consumption of acetic acid , also dangerous. When the general use of pure oxygen as the oxidant, the temperature control at 55 ~ 85 ℃. (4) reaction pressure. Consumption of acetic acid increased pressure in favor of the oxygen is absorbed, and can reduce the consumption of volatilization loss of glacial acetic acid, but the pressure will increase investment in equipment and operating costs increase, and increases the possibility of an explosion. So, just a little pressure to consumption of acetic acid remains liquid at the reaction temperature. When using pure oxygen as the oxidant, at the top of the reactor pressure was about 0.15MPa.
