Specifications Features: 1) Special properties: natural organic compound, mainly composed of resins, posse Features: 1) Special properties: natural organic compound, mainly composed of resins, possesses chemical activity when dissolved in many organic solvents 2) Applications: used for manufacturing of paper, paint, soap and printing ink a) Since rosin is easily softened and oxidized, in the oil paint industry, the carboxylation reaction of resin acid is usually employed to produce resinate for further use b) 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
