Abstract

The invention discloses a production method for hydrogenated rosin glycerol ester. The method comprises the steps that rosin is added into a reaction kettle to be heated and fused, and temperature is maintained; a hydrogenation catalyst is added into the reaction kettle, the mixture is stirred to be uniform, then hydrogen gas is introduced, and the temperature is raised for a reaction for 30-50 minutes, wherein the adding quantity of the hydrogenation catalyst accounts for 0.5%-1% of the total weight of the rosin; filtration is performed, and activated carbon is added for decoloration; glycerol is added into the reaction kettle, then an esterification reaction catalyst is added, ultrasonic waves are introduced into the reaction kettle, heating is performed for a reaction for 20-40 minutes, and filtration is performed to remove the esterification reaction catalyst. The reactions are sufficient at low temperature and low pressure in a short time, and the obtained product is light in color and free of peculiar smells, has a good taste, is chewable and excellent in foaming performance and plasticizing performance, and reaches the level of edible hydrogenated rosin glycerol ester.

Description

technical field [0001] The invention relates to the technical field of rosin deep processing, in particular to a production method of hydrogenated rosin glyceride. Background technique [0002] Hydrogenated rosin glyceride is a product of hydrogenated rosin and glycerin esterification, which is often used as an aging-resistant and non-corrosive tackifying resin for solvent-based pressure-sensitive adhesives, solvent-based universal adhesives, and hot-melt adhesives. The preparation method of hydrogenated rosin glyceride is often to first hydrogenate rosin to generate hydrogenated rosin, and then add glycerol for esterification, but the whole preparation process often requires high temperature and high pressure conditions, and the preparation time is long, which undoubtedly increases the production cost. Contents of the invention [0003] The object of the present invention is to provide a production method of hydrogenated rosin glycerides, which can solve the problem that ...
