Abstract

Procedeu pentru oxidarea ciclohexanului, la ciclohexanol-ciclohexanona, conform inventiei principale cu descrierea nr. 69233, care în scopul diminuarii consumului specific si al cresterii selectivitatii la conversii superioare, realizeaza reactia de oxidare a ciclohexanului cu aer în faza lichida în prezenta unui continut de benzen de 2...4% molar fata de hidrocarbura propaspata si recirculata si alimenteaza în reactor, nepurificata, deci cu un continut de 3...6% produse secundare oxidate, concomitent cu introducerea unei cantitati de catalizator, naftenat de cobalt bivalent de 20...30 ppm dozat egal în fiecare camera a reactorului.Process for cyclohexane-cyclohexane-cyclohexanone oxidation according to the main invention as described in U.S. Pat. 69233, which in order to reduce specific consumption and to increase the selectivity at higher conversions, performs the oxidation reaction of cyclohexane with air in the liquid phase in the presence of a 2-4% molar benzene content relative to the propasted and recirculated hydrocarbon and feeds into unpurified reactor, with a content of 3 to 6% of oxidized by-products, together with the introduction of a quantity of bivalent cobalt naphthenate of 20 ... 30 ppm, equally dosed into each chamber of the reactor.
