| Hazard Information | Back Directory | [Description]
Hydrogenated rosin is one of the modified rosin products. The conjugated double bond of abietic acid type resin acid in rosin is partially or completely saturated with hydrogen under catalyst, certain temperature and pressure. Rosin with partial double bonds saturated with hydrogen is called hydrogenated rosin and contains 75% of dihydroabietic acid. | [Uses]
PARTIALLY HYDROGENATED ROSIN is an important modified rosin product, characterized by good antioxidant properties, low brittleness, high thermal stability, and light color. It is widely used in adhesives, synthetic rubber, coatings, inks, papermaking, electronics, food, pharmaceuticals, building materials, and other industrial sectors. Fully it with a high degree of hydrogenation (such as a colorless, transparent granular product with a softening point of 81℃) is less prone to oxidation and discoloration when added to lead-free fluxes or solder pastes, and is often used in high-grade fluxes and solder pastes, especially lead-free environmentally friendly products. | [Synthesis]
Add rosin into an aluminum or copper pot, heat and melt and continue to heat to 180-220 ° C, add a fresh reduced nickel catalyst under stirring, and react with hydrogen, then the rosin acid can be reduced to dihydroabietic acid, and at the same time Part of the dihydroabietic acid can also be reduced to saturated tetrahydroabietic acid. The product is filtered and vacuum distilled to obtain hydrogenated rosin. |
