Embodiment

[0011] In the preparation method of rosin glyceride of the present invention, the reaction speed is accelerated by 3-5 times by enlarging the catalyst, and the reaction becomes stable and easy to control through the method of enriching polyols, so that the production period is greatly shortened, and the production and equipment efficiency is high In order to improve, the production cost is reduced; and products with light color and high quality are obtained.

[0012] The preparation method of rosin glycerin ester of the present invention comprises the reaction of rosin and glycerin under a catalyst, and high-temperature vacuum removal of remaining glycerin; it is characterized in that: by weight, the material ratio is 100 parts of rosin, not less than 50 parts of glycerin, and 1.5 parts of zinc oxide -2.6 parts of catalyzer, its technique comprises the following steps:

[0013] 60-70 parts of rosin are heated and melted, and the temperature is raised to 250°C,

[0014] Add 30...

Abstract

The invention discloses a preparation method of a rosin glycerol ester. The rosin glycerol ester is prepared from 100 parts of rosin, more than 50 parts of glycerol, and 1.5-2.6 parts of zinc oxide; after rosin reacts with glycerol under the action of a catalyst, and the rest glycerol is removed at a high temperature in vacuum so as to obtain a rosin glycerol ester product provided by the invention. The preparation method has the advantages of low reaction temperature, easiness in control, in high reaction speed improved by 3-5 times, low product production cost and good quality.

Description

technical field [0001] The invention belongs to a rosin deep processing method. Background technique [0002] Rosin is a rich renewable resource in my country, with an annual output of more than 600,000 tons, ranking first in the world. It is composed of a series of resin acids, with a unique chemical structure and multiple chiral centers. The carboxyl group and phenanthrene ring skeleton in the structure can undergo a series of chemical modifications, and it is a natural chiral source material. Rosin can be chemically modified to obtain a series of deep-processing products, which are widely used in various fields in daily life and play a pivotal role in the development of the national economy. The value of these deep-processed products is 2-10 times or even dozens of times higher than that of raw material rosin. At present, my country mainly earns foreign exchange by exporting gum rosin. my country is the country with the largest export volume of gum rosin, accounting for...
