Antiknock properties of furfural derivatives

Preparative amounts of furfuryl alcohol ethers and furfural acetals were prepared from renewable vegetable raw materials. The blending reseach octane numbers of mixing of furan derivatives in straight-run gasoline were estimated: butyl furfuryl ether, 97.8 +/- 7; propyl furfuryl ether, 112 +/- 6; furfural diethyl acetal, 105 +/- 6, furfural ethylene glycol acetal, 108 +/- 7; furfurylamine, 194 +/- 4. These results demonstrate prospects for using furan derivatives as available biofuels.
