bis‐thioether‐di‐phenolate [OSSO]‐type ligand, was discovered to promote the ring‐opening of glycidol with alcohols under mild reaction conditions (0.05 mol % catalyst and 80 °C). The reaction proceeded with high activity (initial turnover frequency of 1680 h−1 for EtOH) and selectivity (>95 %) toward the formation of twelve monoalkyl glyceryl ethers (MAGEs) in a regioselective fashion (84–96 % yield of the non‐symmetric

The present invention relates to a versatile process for the simultaneous production of biocomponents for fuels such as gasoline and diesel, essentially starting from glycerol of biological origin only, comprising a multiplicity of interconnected steps related to hydrogenation, condensation and etherification.
Symmetrical polyols, polyol esters, polyesters, polyurethanes, triazoles, and polyvinylethers derived from glycerol and methods of making the symmetrical polyols, polyesters, polyurethanes, polyhydroxyvinylethers and triazoles are discussed. Also provided is a method of making serinol.

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.
