Usage

Description

PARTIALLY HYDROGENATED ROSIN is a modified rosin product that is obtained by partially or completely saturating the conjugated double bonds of abietic acid type resin acid in rosin with hydrogen under the influence of a catalyst, specific temperature, and pressure. It contains 75% of dihydroabietic acid, which gives it unique properties and a wide range of applications across different industries.

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.
