196 parts by wt. of furfuryl alcohol and 160 parts by wt. dimethyl glutarate (stoichiometric proportions) were mixed and 0.5-0.75% wt. sodium metal added. The mixture was heated to a temperature in the range from 214°-240° F. under a nitrogen atmoshpere. Methanol was evolved and removed as the reaction progressed. After a period of 4 hours, a waxy solid was obtained. After washing the product with water, the residure was a liquid which was identified as difurfuryl glutarate by gas chromatography and mass spectrometric analysis.
