Rosin: At present, most rosin product is used for the manufacturing
of paper, paint, soap and printing ink. Since rosin is easily
softened and oxidized, in the oil paint industry, the carboxylation
reaction of resin acid is usually employed to produce resonates for
further use. While in the producing of synthetic rubber and
printing ink, resin acid is changed into disproportionate rosin,
polymerized rosin, hydrogenated rosin, etc for further use by its
double bond reaction.
