| 100 MHz NMR study of self-condensation of ortho- and para-methylolphenol and their co-condensation with phenol is presented. Reaction rate, co-reaction with phenol, dimethylene ether and phenolic hemiformal intermediates, methylene groups distribution and reaction mechanism in different catalytic conditions are the main topics discussed. The co-condensation rate is mainly dependent on methylolphenol reactivity and is similar with phenol and components of oil shale alkylresorcinols. |
