Bi-acylation of cellulose: determining the relative reactivities of the acetyl and fatty-acyl moieties [PDF]
, 2011 The global reaction between acetic anhydride and a fatty acid yields, at equilibrium, an asymmetric acetic-aliphatic anhydride in a medium containing finally: acetic-fatty anhydride, acetic anhydride, fatty acid, acetic acid and fatty anhydride.

Nature, 1946 VARIOUS attempts have been described1 to acetylate alginic acid by means of acetic anhydride or acetic acid, without or with catalysts, for example, pyridine, acids, etc. Some of the products thus obtained were probably degraded, and it appeared of interest, therefore, to find out whether the acetylation of alginic acid can be done by a relatively mild

Recent advances in the methanol carbonylation reaction into acetic acid
, 2020 Although the high efficiency of the homogeneous processes, using rhodium or iridium complexes, was clearly demonstrated industrially, heterogeneous catalysts offer the advantages of facile product separation and vapor phase operation, which often limit ...
