Abstract
When gum-resin extracted from Pinus trees is treated by destilation, two components are yield:1 Pitch (resinic acids and fatty acids -70-80% of resin) 2. Turpentine (major formed by alpha- ad beta-pinene-20-30%). alpha- ad beta-Pinene are monoterpenic molecules which may suffer isomerizatio, hidration and esterification reactions to afford canfene or limonene, terpenic alcohols (alpha-t…
