About this document
Reactions and Derivatives of Rosin by Thanh Nguyen is a document available to read on EtoBox.
Rosin can undergo both condensation and addition reactions. Its carboxyl group can be esterified with alcohols to produce non-resinous, resinous non-convertible, and resinous convertible products. It can also be neutralized with lime or zinc oxide to produce limed rosin and zinc resinate. Rosin derivatives like lead, cobalt, and manganese resinates are used as driers for oil and varnish. Rosin is susceptible to oxidation of its unsaturated bonds but this can be prevented by hydrogenation. Polymerized rosin
