Resin acid - Wikipedia
Resin acid refers to any of several related carboxylic acids found in tree resins. Nearly all resin acids have the same basic skeleton: three fused rings having the empirical formula C 19 H 29 COOH. Resin acids occur in nature as tacky, yellowish gums consisting of several compounds.
Resin acid - chemeurope.com
Resin acids are protectants and wood preservatives that are produced by parenchymatous epithelial cells that surround the resin ducts in trees from temperate coniferous forests. The resin acids are formed when two- and three-carbon molecules couple with isoprene building units to form mono-, sesqui-, and diterpene structures.

Solubility and toxicity of resin acids - ScienceDirect
Jul 1, 2000 · Pimaric type resin acids are more toxic and less soluble than the abietic type. The discharge of liquid effluent from the pulp and paper industry has, in recent years, become an increasingly important factor in its operation.
Rosin Acid Solubility, Structure, Types, Uses, Hydrogenated
Rosin Acid is the chief component of common resin. It can be found in Pinus kesiya Royle, Pinus insularis (Khasi Pine), Pinus sylvestris (Scotch Pine) and Pinus strobus (Eastern White Pine). The ester of this acid is known as Abietate or Rosin Acid Ester. Rosin Acid is soluble in acetone, ethers and alcohols.
Thermal Stability Evaluation of Resin Acids and Rosin Modified Resins
In this paper, the accelerating rate calorimeter (ARC) method was used to analyze three resin acids (levopimaric acid, neoabietic acid, and dehydroabietic acid) and four rosin-modified resins (hydrogenated rosin, disproportionated rosin, hydrogenated rosin glyceride, and hydrogenated rosin pentaerythritol ester) and to investigate their ...
