- C07C 37/01 by replacing functional groups bound to a six-membered aromatic ring by hydroxy groups, e.g. by hydrolysis
- C07C 37/06 by conversion of non-aromatic six-membered rings or of such rings formed in situ into aromatic six-membered rings, e.g. by dehydrogenation
- C07C 37/08 by decomposition of hydroperoxides, e.g. cumene hydroperoxide
- C07C 37/11 by reactions increasing the number of carbon atoms
- C07C 37/48 by exchange of hydrocarbon groups, which may be substituted, from the same of other compounds, e.g. transalkylation
- C07C 37/50 by reactions decreasing the number of carbon atoms (C07C37/04, C07C37/045, C07C37/055, C07C37/08 take precedence)
- C07C 37/58 by oxidation reactions introducing directly hydroxy groups on a =CH-group belonging to a six-membered aromatic ring with the aid of molecular oxygen
- C07C 37/60 by oxidation reactions introducing directly hydroxy groups on a =CH-group belonging to a six-membered aromatic ring with the aid of other oxidants than molecular oxygen or their mixtures with molecular oxygen
- C07C 37/62 by introduction of halogen; by substitution of halogen atoms by other halogen atoms
- C07C 37/64 Preparation of O-metal compounds with O-metal group bound to a carbon atom belonging to a six-membered aromatic ring
- C07C 37/68 Purification; separation; Use of additives, e.g. for stabilisation
