METHODS OF MAKING ALKYL LACTATES AND ALKYL LEVULINATES FROM SACCHARIDES

Unique methods have been developed to convert saccharides into value-added products such as alkyl lactates, lactic acid, alkyl levulinates, levulinic acid, and optionally alkyl formate esters and/or hydroxymethylfurfural (HMF). Useful catalysts include Lewis acid catalysts and Brønsted acid catalyst...

More Information
Summary:Unique methods have been developed to convert saccharides into value-added products such as alkyl lactates, lactic acid, alkyl levulinates, levulinic acid, and optionally alkyl formate esters and/or hydroxymethylfurfural (HMF). Useful catalysts include Lewis acid catalysts and Brønsted acid catalysts including mineral acids, metal halides, immobilized heterogeneous catalysts functionalized with a Brønsted acid group or a Lewis acid group, or combinations thereof. The saccharides are contacted with the catalyst in the presence of various alcohols.
