Abstract
The present invention discloses a hydrogenated rosin preparation method, which comprises: adding rosin into a reaction kettle, carrying out heating melting, and carrying thermal insulation for 20-30 min; adding a catalyst to the reaction kettle, uniformly stirring, introducing hydrogen gas, and heating to a temperature of 110-130 DEG C, wherein the addition amount of the catalyst is 0.2-0.5% of the total weight of the rosin; and introducing microwave into the reaction kettle, reacting for 20-30 min, filtering, and adding active carbon to decolorize. According to the present invention, the microwave is introduced during the production process, such that the reaction is complete under the conditions of low temperature, low pressure and short time; the nanometer zinc oxide is used as the hydrogenation catalyst, has the reaction activity equivalent to the general palladium-titanium alloy catalyst, and further has advantages of reaction temperature lowering, reaction pressure lowering, and production process simplifying; and the obtained product is lighter in color, is water-white color or nearly colorless, and has the high economic value.
Description

The present invention relates to rosin deep process technology field, especially a kind of preparation method of staybelite.
Background technology
Rosin is the reproducible natural resource of China's abundant, because having special molecular structure and performance, and be widely used in the industries such as electronics, coating, tackiness agent, ink, pigment, synthetic rubber, food, intermetallic composite coating, building materials, be also used as synthesis fine chemistry industry and novel high polymer material.Along with rapid development of economy, the specification of quality of these industries to rosin and deep processed product thereof also improves constantly, and one of color relation quality index that to be rosin and deep processed product thereof important, control color well, just control the rank of rosin and deep processed product thereof to a certain extent, water-white hydrogenating rosin is the staybelite product of current highest level.
But, at present, in water-white hydrogenating rosin preparation process, often need the processing condition of high temperature, high pressure, condition of high vacuum degree, and the reaction times is longer, therefore, researchist make great efforts to seek a kind of can under lower level, produce the method for water-white hydrogenating rosin in the short period of time.
Summary of the invention
The object of this invention is to provide a kind of preparation method of staybelite, the preparation method of this staybelite can solve the processing condition often needing high temperature, high pressure, condition of high vacuum degree in water-white hydrogenating rosin preparation process, and the problem that the reaction times is longer.
In order to solve the problem, the technical solution used in the present invention is:
The preparation method of staybelite of the present invention comprises the following steps:
A, rosin add in reactor, heating and melting, are incubated 20 minutes ~ 30 minutes;
B, in reactor, add catalyzer, stir, then pass into hydrogen, be warming up to 110 DEG C ~ 130 DEG C; Wherein, the add-on of catalyzer is 0.2% ~ 0.5% of rosin gross weight;
C, in reactor, pass into microwave, react 20 minutes ~ 30 minutes, filter, add gac and decolour.
In technique scheme, scheme can also be more specifically: described catalyzer is nano zine oxide.
Further, the flow of hydrogen is 300 ls/h ~ 500 ls/h.
Further, described micro-wave frequency is 1500 megahertz ~ 2300 megahertzes, and microwave power is 500 watts ~ 800 watts.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention passes into microwave in process of production, makes reaction at low temperature, low pressure and sufficient reacting in the short period of time; Adopt nano zine oxide as hydrogenation catalyst, there is the reactive behavior suitable with conventional palladium titanium alloy catalysts, and reduce temperature of reaction and pressure, simplify production technique; Products obtained therefrom color is more shallow, for water white or close to colourless, economic worth is higher.
