摘要： Ionic liquids and cellulose ester compositions and processes for producing ionic liquids and cellulose esters. Cellulose esters can be produced by esterifying cellulose in a reaction medium comprising one or more halide ionic liquids and at least one binary component. Cellulose esters prepared via the methods of the present invention can have a degree of substitution (“DS”) of at least 1.5 and can comprise a plurality of ester substituents, where at least 50 percent of the ester substituents comprise alkyl esters having a carbon chain length of at least 6 carbons.

摘要： Ionic liquids and cellulose ester compositions and processes for producing ionic liquids and cellulose esters. Cellulose esters can be produced by subjecting a cellulose-ionic liquid solution comprising cellulose, one or more ionic liquids, and one or more co-solvents to esterification to thereby produce an esterified medium comprising a cellulose ester. The co-solvents employed in the present invention can be either miscible or immiscible with the cellulose-ionic liquid solution but can be readily dispersed or soluble in the esterified medium.

摘要： This invention provides cellulose ester interpolymers, and methods of oxidizing cellulose interpolymers and cellulose ester interpolymers. The invention also provides routes to access carboxylated cellulose ester derivatives with high acid numbers wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be accessed. The interpolymers of the present invention have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.
