| Comments |
Gum rosin, the residue remaining after the steam distillation of pine resins to produce turpentine, is used in soldering fluxes. Most of the resin present in gum rosin is 1-abietic acid. Heat decomposes gum rosin into alcohols, aldehydes, carbon monoxide, carbon dioxide, methane, abietic acid, and related di-terpene acids. [ACGIH] See "Colophony." |
