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.
本公开涉及一种从生物衍生的醛与2,3-丁二醇催化转化制备环丙缩醛的方法。这些方法在无溶剂反应体系中运行,并通过相分离和随后的倾倒来分离产品缩醛。环丙缩醛具有出色的性能,可与柴油燃料混合使用,包括提高十六烷值和密度,降低粘度、冰点和烟尘生成。
