Description

Application

Propionic anhydride can be used:

As an esterifying reagent in the modification of cassava starch by acylation reaction.
As a reactant along with anisole in the synthesis of 4-methoxypropiophenone using various solid acid catalysts via Friedel−Crafts acylation reaction.
As a reagent in the synthesis of cyanohydrin esters by treating KCN with aldehyde in presence of bimetallic titanium(salen) complex catalyst.

Polyethylenimine (750 kDa) has been derivatized to influence the proton sponge mechanism and hydrophobic-hydrophilic balance. The polymer was acylated using acid anhydrides of varying carbon chain length, followed by cross-linking with PEG-bis-P to form compact nanoparticles. The chemical linkages in
