The present invention relates to a process for preparing cyclic acetals that can be used as components for diesel fuel. More specifically, the present invention relates to a process for preparing cyclic acetals having an ethereal function that can be used as diesel fuel components preferably starting from precursors of a biological origin such as, for example, starting from glycerol of a biological origin. With the process of the present invention, it is possible, for example, to prepare etherified cyclic acetals having a 1,3-dioxolane and 1,3-dioxane structure, that can be used as diesel fuel components, starting from non-etherified cyclic acetals having a 1,3-dioxolane structure, which in turn can be obtained from glycerol derivatives, in particular glycerol of a biological origin, such as 1,2-diols, for example, 1,2-propanediol.
本发明涉及一种制备环状缩醛的方法,该缩醛可用作柴油燃料的组分。更具体地说,本发明涉及一种制备具有以太功能的环状缩醛的方法,该缩醛可用作柴油燃料的组分,最好是从生物起源的前体开始制备,例如从生物起源的甘油开始制备。使用本发明的方法,例如可以从具有1,3-二氧兰结构的非醚化环状缩醛开始制备具有1,3-二氧兰和1,3-二氧杂环结构的醚化环状缩醛,这些醚化环状缩醛可用作柴油燃料的组分,而非醚化环状缩醛则可以从甘油衍生物中获得,特别是从生物起源的甘油中获得,例如1,2-二醇,例如1,2-丙二醇。
