Recent Progress on Derivation and Chemical Modification of Rosin Acids

Rosin has been recognized as one of the most important renewable resources in the forest chemical industry. It is a complex mixture of acidic and neutral compounds. The isolation method, derivation and modification of rosin acids were summarized mainly, such as isomerization, disproportionation, hydrogenation, maleation and esterification of rosin acids were reviewed. It is considered that the derivation and modification of rosin acids is the most important way to use rosin in higher value.
