A simple, solvent free method for transforming bio-derived aldehydes into cyclic acetals for renewable diesel fuels†
Abstract
The acetalization of 2,3-butanediol with bio-derived C4–8 aldehydes has yielded a route to substituted 1,3-dioxolanes from small bio-building blocks. The reported reaction system features excellent carbon yields (>93%), atom economy (>89%) and phase separation of the analytically pure product which eliminates elaborate purification processes and facilitates simple catalyst recycling. The 1,3-dioxolanes offer performance advantages over traditional diesel and have the potential to augment petroleum derived fuels.
