ELECTROLYZER FOR THE OXIDATION OF BENZENE TO P-BENZOQUINONE

摘要

the invention relates to a electrolizor for oxidation of benzene to p - benzochinona.electrolizorul, according to the invention, is constituted of electrodes of lead or lead alloy suprapusi antimony and / or silver, isolated by means of extrusion of polyethylene.anozii are made of rectangular holes which are charged in like circular by circulating the electrolyte, and catozii, same shape with anozii,they charged orifices rectangular, so that the surface activaacatodului to be much smaller than the surface active anodului.this construction has electrolizorului porous diaphragms or membranes to allow renunciation for changing ion separation compartments electrodice,because procesulca todic unwanted reduction of p - benzochinonei formed at the anode is inhibited by imposing a cathode current densities much greater than the diffusion part reducerii p - benzochinonei.in the condition in which yields, for getting some big power from p - benzochinona formed, it is necessary to work at relatively low densities anode.inhibition of the cathodic process is accomplished at anodica reports surface: surface catodica greater than 5.
