Furfuryl esters, preparation

Uses Solvent for dyes and resins preparation of furfuryl esters furan polymers solvent for textile printing manufacturing wetting agents and resins penetrant flavoring corrosion-resistant sealants and cements viscosity reducer for viscous epoxy resins. 

They are both chrysanthemic acid esters of (5-benzylfuran-3-yl)methanol (Elliott alcohol, 1) [15]. Patented methods [16] for the industrial preparation of Elliotf s alcohol are demanding or such as to be hardly exploited in industrial-scale plants. For instance, in one of these methods [17] (5-benzyl-3-furyl)methanol is obtained by a sequence of Claisen condensation of benzyl cyanide and a dialkyl succinate, hydrolysis, esterification, protection of the ketone group, formylation, cyclization to 5-benzyl-3-furfuryl ester and reduction to alcohol with lithium aluminium hydride.
