Summary
Furfuryl esters were prepared from linseed oil and methyl palmitate by alcoholysis using metallic sodium as the catalyst. They were also prepared from linseed oil and from methyl oleate by partial saponification in furfuryl alcohol. These esters, although containing conjugated double bonds, did not possess any increased drying power.
Iodine numbers were determined by several methods, and, except with the Woburn reagent, the furfuryl group was found to exhibit a higher iodine number when combined as an ester than when present as the free alcohol.
Furfuryl esters were found to polymerize to products of greatly decreased iodine number and increased acidity, showing that polymerization involved both deacylation and reaction at the double bonds of the furan ring.
