Abstract Disclosed herein are processes for producing levoglucosenone. In one embodiment, a carbohydrate feedstock is contacted with a first solvent and a homogeneous acid at a at a first temperature between about 20 °C and about 35 °C and for a first reaction time; the solvent is then removed to obtain an acid-impregnated feedstock, which may optionally be mechanically processed; and the acid-impregnated feedstock is then contacted with a second solvent at a second temperature between about 150 °C and about 250 °C for a second reaction time sufficient to form a product mixture comprising levoglucosenone. L'invention concerne des procédés de production de lévoglucosénone. Dans un mode de réalisation, une charge de départ de glucides est mise en contact avec un premier solvant et un acide homogène à une première température entre environ 20°C et environ 35°C et pendant un premier temps de réaction; le solvant est ensuite éliminé en vue d'obtenir une charge de départ imprégnée d'acide, qui peut éventuellement être traitée mécaniquement; et la charge de départ imprégnée d'acide est ensuite mise en contact avec un deuxième solvant à une deuxième température entre environ 150°C et environ 250°C pendant un deuxième temps de réaction suffisant pour former un mélange de produits comprenant de la lévoglucosénone.
