The main components which can cause pitch trouble in the process of paper making with Masson pine TMP was simulated by using fatty acid,resin acid and oleic triglyceride as model materials.

Nano-Ni was first used as catalyst for disproportionation of resin acid.

The morphological variation characteristics of resin acid,as well as titration correction of the unsaponifiable matter during rosin saponification were discussed theoretically.

The law of thermo isomeric changes of the pimaric,ellioti pimaric, levopimaric,longifolic,dehydropimaric,abietic and neoabietic acids in the oleoresin of Pinus elliottii were studied in a comparison with those of resin acids in the oleoresin of Pinus massoniana .

This article gave a review on the structures and biological activities including antitumor,antivirus and antibacterial activities of resin acids and their derivatives including 52 compounds.

Synthesis of fructone using acidic resin as a catalyst;

A new method to synthesize N,N' -diphenyl thiourea (DPTU) from aniline and CS 2 was developed in the presence of acidic resin as catalyst under reflux temperature for 6 h with the yield of 82.

DPTU was selectively synthesized using aniline and CS2 as reactants and acidic resin as catalyst under mild conditions.
