The kinetics of the acid catalysed condensation of furfuryl alcohol in tetrahydrofuran medium have been investigated by means of gel permeation chromatography using a 100A ultrastyragel column and tetrahydrofuran as the mobile phase. The reaction has been found to be second order. Comparison of the kinetics of condensation of the monomer and the 5-furfuryl furfuryl alcohol dimer indicates higher rates of reaction for condensation of the dimer as a consequence of the greater stability of the tertiary and allylic carbocations formed during its condensation or the condensation of higher alcohol oligomers. The study of the side reaction which results in furan ring cleavage leading to the formation of laevulinic acid, whose proportion has been estimated by pH titration, was restricted to furfuryl alcohol condensation reactions.
