PMID: 27702533
Carbohydr Polym. 2017 Jan 02;155:440-447. doi: 10.1016/j.carbpol.2016.08.067. Epub 2016 Aug 30.

Regioselectively substituted curdlan esters were synthesized by protecting the C6 primary hydroxyl group with a triphenylmethyl group followed by the acylation of the secondary hydroxyl groups at C2 and C4. The subsequent detritylation of C6 trityl group under acidic...

Acetylation and characterization of xylan from hardwood kraft pulp.

Carbohydrate polymers

Fundador NGV, Enomoto-Rogers Y, Takemura A, Iwata T.
PMID: 34662947
Carbohydr Polym. 2012 Jan 04;87(1):170-176. doi: 10.1016/j.carbpol.2011.07.034. Epub 2011 Jul 28.

Alkaline treatment of eucalyptus hardwood kraft pulp with 10% NaOH yielded 6-8% xylan. The acetylation of the extracted xylan was carried in DMAC/LiCl/pyridine system to obtain a series of xylan acetates with different degrees of substitution (DS). Structure elucidation...
