Description
Summary:Here we report the screening of various homogeneous acid catalysts in the oligomerization of glycerol at 150 °C. Under optimized conditions, a mixture of oligoglycerol with an average degree of oligomerization of 3.4 was obtained at a glycerol conversion of 80%. At such a conversion, the selectivity to oligoglycerols was higher than 90%. Oligoglycerols were then successfully alkylated, offering an attractive route to valuable molecules (biosurfactants or hydrotropes). Here, we report the oligomerization of glycerol in the presence of various Brønsted and Lewis acid catalysts. Under optimized conditions, oligoglycerols with an average degree of oligomerization of 3.4 were selectively obtained at 80% conversion of glycerol.
