KINETICS OF RESINIFICATION OF FURFURYL ALCOHOL IN ACIDIC BUFFER SOLUTIONS

Abstract

Kinetic informations on the resinification of furfuryl alcohol have been derived  from the rate of increase of colour intensity measured with a photoelectric colori-  meter. the resinification being carried out isothermally in McIlvaine's aqueous  buffer solutions in the pH range  2.2-3.4.  The activation energy for resinification  is found to increase exponentially with pH. The time required to reach the extent  of reaction at which a resin layer separates out from the aqueous solution increases  with increasing pH and decreases with increasing temperature. An exponential  expression relating the tune of separation with pH and temperature has been derived.
