- PREPARATION OF CYCLIC ACETALS FOR FUEL
-
The present disclosure relates to methods for preparing cyclic acetals from the catalytic transformation of bio-derived aldehydes with 2,3-butanediol. The methods operate in a solvent-free reaction system and provide isolation of the product acetals through phase separation and subsequent decantation. The cyclic acetals exhibit excellent properties for blending with diesel fuel, including increased cetane number and density, and decreased viscosity, freezing point, and soot formation.
