    摘要： Methods for integrating the production of cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF) from cellulose are provided. The methods use milder acid hydrolysis conditions than those for maximal CNC production to achieve reduced degradation of cellulose into soluble sugars. Also provided are negatively charged cellulosic solid residues (CSRs) in the form of cellulose fibers (CF) and/or cellulose microfibrils (CMF) during the acid hydrolysis, as well as CNFs fabricated from the CSRs.

The method includes providing melaninic, ligninic, chitinic, and/or cellulosic material and providing an oxoacid ester of phosphorus or a mixture of an oxoacid of phosphorus and an alcohol. A blend of the melaninic, ligninic, chitinic, and/or cellulosic material, the oxoacid ester of phosphorus or the mixture of the oxoacid of phosphorus and alcohol is formed. The blend is then treated under conditions effective to solubilize the melaninic, ligninic, chitinic, and/or cellulosic material.

    摘要： A process for preparing a sulfate ester of a polyhydroxy polymer which is a partially substituted polysaccharide or a polyvinyl alcohol which contains ether groups, ester groups other than sulfate, or a mixture of ether groups and ester groups other than sulfate. A nitrite ester of the partially substituted polymer is reacted with sulfur trioxide or a complex thereof to obtain a mixed nitrite:sulfate ester which is then reacted with a protic solvent to remove residual nitrite ester groups.A process for preparing a substantially uniformly substituted colloidal cellulose sulfate having a degree of substitution of about 1.1 to 2.0. A nitrite ester of cellulose having a degree of substitution less than about 2 is reacted with sulfur trioxide or a complex thereof to obtain a mixed nitrite:sulfate ester which is reacted with a protic solvent to remove residual nitrite ester groups.A process for preparing a substantially uniformly substituted cellulose sulfate having a degree of substitution ranging up to about 1.1. A nitrite ester of cellulose having a degree of substitution of about 2 to below about 3 is reacted with sulfur trioxide or a complex thereof to obtain a mixed nitrite:sulfate ester which is then reacted with a protic solvent to remove residual nitrite ester groups.
