Furfural Dipropyl Acetal as a New Fuel Additive: Synthesis and Properties

Аннотация

Liquid-phase acetalization of 1-propanol with furfural was studied. A procedure was recommended for preparing furfural dipropyl acetal on a sulfonic cation-exchange resin. The possibility of repeated use of the catalyst without significant loss of the activity was demonstrated. An experimental sample was synthesized, isolated, purified, and characterized. Its specific heat of combustion, density, refractive index, induction period in the mixture, and antiknock and lubricating properties were determined. Furfural acetals show promise as a fuel additive.
