Esterification cellulose with succinic anhydride

Hydroxypr opylm ethyl cellulose acetate succinate By the esterification of hydroxypropylmethyl cellulose with acetic anhydride and succinic anhydride Film coating. Enteric coating... 

The light stability of wood panel treated with acetic anhydride, succinic anhydride, maleic anhydride, and phthalic anhydride was compared. Results from the solid state CPMAS NMR analyses revealed that the esterification of holocelluloses occurred mainly at the C-6 position in the amorphous cellulose component. ... 

The hydrophobization of cellulose surface was often achieved thanks to the well-known aptitude of cellulose macromolecules to undergo esterification reactions. The main coupling agents used to esterify cellulose using nonswelling solvents, in order to limit the reaction to the fibre s surface, are summarized in Scheme 18.1, namely the classical acetic anhydride [24] (I), alkyl ketene dimer (AKD) II, alkenyl succinic anhydride (ASA) III, fatty acids (IV, with n var5fing from 6 to 22) or their chlorides, poly-(propylene-gra/f-maleic anhydride) (V), trifluoroethoxy-acetic acid (VI) and its anhydride, as well as several other perfluoro-derivatives, p5Tomellitic anhydride (VII), styrene-maleic anhydride copolymer (VIII) and methacrylic anhydride (IX).
