Inventor: THOMA MATTHIAS
IPC: C07C37/00
Filed: 1968-12-10
Abstract: Methylphenols with more than one CH3- substituent are isomerised and disproportionated in liquid phase by heating in the presence of phenol, with an Al-phenolate, Al-methylate or Al2O3 catalyst, to 340-400 degrees C for 2-10 hrs. under 15-50 atms. gauge.
