Phosphorylase reactions typically involve only scant hydrolysis (Luley-Goedl and Nidetzky, 2010; Puchart, 2015), in consequence of exclusion of reaction with water from the enzyme active site (De Groeve et al., 2009; Kuhaudomlarp et al., 2019; O'Neill et al., 2017). The αGlc1P ...
Reaction curves for the simplest of cellulose acetylation systems; namely, the homogeneous reaction of secondary cellulose acetates with acetic acid and water, were studied. These reactions were found to be slow and complex, consisting of two interdependent simultaneous reversible second-order processes....
(II) in combination with water catalyses a series of cascading steps for lactic acid formation, including the isomerization of glucose formed via the hydrolysis of cellulose into fructose, the selective cleavage of the C3–C4 bond of fructose to trioses and the selective conversion of trioses ...
Cellulose, a major component of woody biomass, was reacted in hot-compressed water using a sodium carbonate catalyst, a reduced nickel catalyst or no catalyst at different reaction temperatures from 200 to 350°C. The reaction mixture was separated into oil, gases, residue and aqueous phase to...
In 1892, the foundation of the Viscose process changed the approach by involving the activation of cotton and wood cellulose in aqueous sodium hydroxide solution followed by reaction with CS2to form a cellulose xanthate (Cross et al.1892). After dissolution in alkaline solution, the cellulose xanth...

The zero point of the "reaction time" was defined as the time point at which the required temperature was reached. When the reaction ended, the reactor was immediately quenched to room temperature in an ice-water bath. The products were quantified by gas chromatography (GC, Agilent 7820 A...
They are produced through reaction of cellulose with organic acids, anhydrides or acid chlorides. Cellulose acetate is one of the oldest bio-based polymers in the world. It was first investigated by Schützenberger [27] in 1865. CA is produced in a two-step esterification process. At first, ...
