Abstract
A phenol is produced by heating water and a cyclic or acyclic alkane or alkene of 6-10 carbon atoms at a temperature of 350.degree. to 700.degree. C in the presence of a metal oxide catalyst. Exemplary is the heating of water and cyclohexane in a nitrogen atmosphere and in the presence of ZnO/TiO.sub.2 to produce phenol.
Claims14
A process which consists essentially in reacting a cyclic or an open-chain alkane or alkene of 6 to 10 carbon atoms having a continuous chain of at least six successive carbon atoms, each of which is bonded directly to no more than three carbon atoms, with water in a nonoxidative atmosphere at a temperature of 350.degree. to 700.degree. C and at a contact time of about 0.01 second to about 10 minutes, in the presence of a metal oxide catalyst selected from oxides of Al, Bi, Cd, Ce, Cr, Cu, Fe, In, Mn, Mo, Sn, Te, Th, Ti, U, V, W, Zn and Zr to produce a phenol.
