What is Octenyl succinic anhydride ?
Description
Octenyl succinic anhydride is an important intermediate of fine chemicals. It has high chemical reactivity because its molecules contain carbon-carbon double bonds and carboxylic acid ligands. Under appropriate conditions, a series of reactions such as addition, Chemicalbook substitution, reduction, acetylation, hydrolysis and polymerization can occur, and various derivatives can be synthesized. Alkyd resin can be synthesized by reacting with alcohol, acid amine can be synthesized by reacting with amine, and starch can be modified.
The Uses of Octenyl succinic anhydride
Octenyl succinic anhydride can be used to esterify starch to yield a hydrocolloid with amphiphilic properties, octenyl succinylated starch (OS-starch). Octenyl succinic anhydride (OSA) modification affects the interaction between molecules on the outer surface of two starch granules by changing the molecular structure of the outer surface.
