PRODUCTION OF LEVOGLUCOSENONE

摘要

Disclosed herein are processes for producing levoglucosenone. In one embodiment, the process comprises the steps: a) contacting in a continuous manner a carbohydrate source, a solvent, and an acid in a continuous liquid phase reactor under reaction conditions sufficient to form a reaction mixture comprising levoglucosenone, wherein the reaction conditions include a liquid residence time in the reactor between about 0.1 minutes and about 20 minutes; b) withdrawing a portion of the reaction mixture from the reactor to obtain a product stream comprising levoglucosenone; and c) optionally, isolating levoglucosenone from the product stream.
