| titleOfInvention | A kind ofly prepare the method for cellulose and lignin as solvent normal pressure ultrasonic wave is auxiliary taking the height alcohol that boils |
| abstract | The invention discloses and a kind ofly prepare the method for cellulose and lignin as solvent normal pressure ultrasonic wave is auxiliary taking the height alcohol that boils, first material of vegetable origin is processed and obtained material of vegetable origin powder, it is that the height of A boils in alcohol solution that powder is added to volume fraction, then adds by H 2 SO 4 With the composite catalyst of HAc composition, under ultrasonic wave is auxiliary, normal pressure boiling reflux 3.5～5h, filters to get filtrate and filter residue; Filter residue soaks at least one times with the height that volume fraction the is B alcohol solution that boils, filter the filter residue obtaining and clean at least one times through water, then through centrifugation, dry, pulverize the cellulose described in obtaining; The filtrate that each filtration produces is mixed, and in filtrate, adds alkali lye to be adjusted to neutrality, and the filter residue leave standstill, suction filtration obtaining after washing and being dried, obtains described lignin again; Described volume fraction B>A. The present invention is taking agricultural waste material as raw material, composite catalyst and ultrasonic wave auxiliary under, under temperate condition, separate and obtain cellulose and lignin. |
