1.1-1.3; 2.1-2.3; 3.1-3.3; 4.1-4.3; 5.1-5.3; 6.1-6.3; 5.1-5.3 Example 6
(1) after the cellulose hydrolyzate is concentrated, the concentrated hydrolyzate of cellulose is obtained, Add CaCl 4.0 g and n-butanol 18.5 g to 30 g of cellulose concentrated hydrolyzate, 100 insulation reaction for 2.5h, of which, The composition of cellulose concentrated hydrolyzate is levulinic acid 5.9g, Formic acid 2.3g, water 21.4g and other biomass hydrolysis by-products 0.4g; (2) the reaction is completed, the temperature is lowered to 45 ° C, the sedimentation is layered, and the organic phase is separated, The mass of the organic phase is 26.2g; (3) organic phase obtains butyl levulinate and butyl formate respectively through distillation, The yield of butyl formate was 84.2 wt.%, The yield of butyl levulinate was 99.8 wt.%;
