## Abstract A kinetic study of the first step in the reaction of phenol and formaldehyde, the formation of __ortho‐__ and __para__‐hydroxymethylphenol, is described. It is found that when using NaOH or KOH as a catalyst under weakly alkaline conditions (pH = 8.5‐10.5) at 30° C, the __para__‐positi
## Abstract The hydroxymethylation of phenol has been re‐investigated in the pH range 8.5‐12.5 at 30° in dilute aqueous solutions. The following rate equation covers the results quantitatively: in which [F], [P] and [P^−^] denote the concentrations of the formaldehyde molecules, phenol molecules
