Description
Technical field
The present invention relates to rosin deep process technology field, especially a kind of preparation method of hydrogenated rosin.
Background technology
Rosin is the reproducible natural resources of China's abundant, because having special molecular structure and performance, and extensively should
For industries such as electronics, coating, adhesive, ink, pigment, synthetic rubber, food, intermetallic composite coating, building materials, synthesis essence is also served as
Refine work and novel high polymer material.With rapid development of economy, quality of these industries to rosin and its deep processed product
It is required that also improve constantly, and color is exactly one of rosin and its important quality index of deep processed product, controls color, one
Determine the rank with regard to control rosin and its deep processed product in degree, water-white hydrogenating rosin is the hydrogenated rosin of current highest level
Product.
However, at present, the technique bar of high temperature, high pressure, condition of high vacuum degree is generally required in water-white hydrogenating rosin preparation process
Part, and the reaction time is longer, therefore, researcher make great efforts to seek it is a kind of can be under relatively low level, in the shorter time
The method of interior production water-white hydrogenating rosin.
The content of the invention
It is an object of the invention to provide a kind of preparation method of hydrogenated rosin, the preparation method of this hydrogenated rosin can be solved
Certainly generally require the process conditions of high temperature, high pressure, condition of high vacuum degree in water-white hydrogenating rosin preparation process, and the reaction time compared with
Long the problem of.
In order to solve the above problems, the technical solution adopted by the present invention is：
The preparation method of hydrogenated rosin of the present invention comprises the following steps：
A, rosin are added in reactor, heating melting, are incubated 20 minutes~30 minutes；
B, catalyst is added into reactor, stir, then pass to hydrogen, be warming up to 110 DEG C~130 DEG C；Wherein,
The addition of catalyst is the 0.2%~0.5% of rosin gross weight；
C, it is passed through microwave into reactor, reacts 20 minutes~30 minutes, filtering, add activated carbon and decolourized.
In above-mentioned technical proposal, more specifically scheme can also be：The catalyst is nano zine oxide.
Further, the flow of hydrogen is 300 ls/h~500 ls/h.
Further, the frequency of the microwave be 1500 megahertzs~2300 megahertzs, microwave power be 500 watts~
800 watts.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
The present invention is passed through microwave in process of production so that reaction is in low temperature, low pressure and is reacted in the short time abundant；Adopt
With nano zine oxide as hydrogenation catalyst, with the reactivity suitable with conventional palladium titanium alloy catalysts, and reduce anti-
Temperature and pressure is answered, simplifies production technology；Products obtained therefrom color is shallower, is water white or close to colourless, economic value is higher.
