Efficient fractionation of pure hemicellulose with high DP from bleached hardwood pulp using LiBr·3H2O and co-production of dissolving pulp

Hemicellulose was efficiently fractionated from BHKP using LBTH with the coproduction of high-quality dissolving pulp. The obtained hemicellulose was pure glucuronoarabinoxylan with high DP (>200) and unique crystalline and nano structure.
