Directed Study of Abietic Acid Reaction in Pine Rosin under Non-Precious-Metal Catalyst

Pine rosin of Pinus merkusii Jung at de Vriese is produced industrially from a distillation process pine sap. The high total Indonesian production leads the primary derivatization strategy into several derivates to fulfill market demand. Abietic acid (AA) major compound in rosin, used as object observation this study. general methodology for transformation reported involves using palladium (Pd) and platinum (Pt)-based catalysts. Both are precious metal catalysts proceed with oxidative dehydrogenative-aromatization rosin. synthesized product provides dehydroabietic (DHA) derivatives yield. This paper reports that non-precious metal-based such iron (Fe), zinc (Zn), or copper (Cu) iodine (I2) were applied deliver reaction by steam cracking without nitrogen (N2) oxygen (O2) economical, efficient, greenway’s catalyst. It was found similar isolated, including by-products. Under temperatures various transitions halogen FeCl3-I2 Cu(NO3)2.3H2O ZnCl2 catalyst, four compounds identified employing spectroscopic methods product: 7-hydroxy-dehydroabietic (5), 1,7-dihydroxy-dehydroabietic (6), 7-isopropyl-1-methylphenanthren-9-ol (7) polymer (8). modified mainly an emulsifier synthetic rubber industry, varnish, ink, sizing, etc. products determined based on LC-MS/MS, UV-Vis, ATR-FTIR spectroscopy.
