Problems solved by technology

At present, there are still great shortcomings in the process of producing light-colored rosin resin, such as complex process, long reaction time, high catalyst cost, easy deactivation, etc., and most of them adopt high-pressure hydrogenation process, which virtually increases the cost of the product. And the process is more difficult to control, resulting in poor product quality

Abstract

The invention belongs to the technical field of rosin processing, in particular to a preparation method of super light-colored rosin resin. The method comprises the following preparation steps: firstly preparing a catalyst A for rosin catalytic hydrogenation, then adding rosin and the catalyst A into a reaction kettle, afterwards, sealing, then vacuumizing, detecting leakage and exhausting air, then keeping ordinary pressure in the reaction kettle, then heating to fuse the rosin, afterwards, introducing hydrogen gas to react, then filtering and performing negative pressure removal of easy volatile ingredients to obtain hydrogenated rosin; then enabling the hydrogenated rosin to react with glycerinum to prepare rosin glycerin ester, and finally cooling, pelleting and packaging to obtain thesuper light-colored rosin resin.

Description

technical field [0001] The invention belongs to the technical field of rosin processing, in particular to a preparation method of ultra-light-colored rosin resin. Background technique [0002] Rosin has many excellent properties such as anti-corrosion, moisture-proof, adhesion, emulsification, etc., and is widely used in papermaking, ink, soap, food, medicine and other industries. Rosin is an abundant renewable resin in nature obtained from the processing of pine resin. Pine resin is the oily liquid that flows out after the pine tree is cut. The pine resin is colorless just after being picked from the tree. When it is placed in the air, the turpentine in the pine resin will volatilize, and the last remaining solid substance is rosin. Rosin is mainly composed of some resin acids and some neutral substances. Resin acids are a general term for a class of compounds. The structure is a three-membered ring phenanthrene skeleton structure. It contains two active groups, double bon...
