Abstract
The invention discloses a preparation method of light-colored rosin glyceride, belonging to the technical field of deep processing of rosin. The preparation method comprises the following steps: putting zeolite into a lead nitrate solution, soaking, then taking out, firstly baking until the water content is 20-30%, then roasting at 300-450 DEG C, and cooling to obtain a substance A for later use; putting rosin into a reaction kettle, controlling the air intake quantity of nitrogen, heating and melting, adding the substance A, rising temperature and then performing heat-preservation reaction 1; adding glycerin, zinc oxide, sodium thiosulfate and calcium hypophosphite, firstly performing heat-preservation reaction at 200-220 DEG C, then rising the temperature to 270-280 DEG C and performing heat-preservation reaction; and performing vacuum pumping to remove low-boiling-point substances, cooling, and discharging material to obtain the light-colored rosin glyceride. According to the preparation method disclosed by the invention, oxidation of rosin is furthest reduced so as to prepare the light-colored rosin glyceride with very light colors.
Description
Technical field
The invention belongs to rosin deep process technology field, relate in particular to a kind of preparation method of pale rosin glyceryl ester.
Background technology
Rosin is taking pine resin as raw material, the non-volatile natural resin obtaining by different processing modes.Rosin is important industrial chemicals, is widely used in the industries such as soap, papermaking, paint, rubber.In addition, rosin also can be made ester gum by deep processing, and compared with rosin, its acid number significantly reduces, and embrittlement and being clamminess property reduce, and weathering resistance improves.But, due to rosin in deep-processing process with oxidation, cause the color of the ester gum making excessively dark, cannot reach the demand in market.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of preparation method of pale rosin glyceryl ester, and the ester gum that the method makes is of light color.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A preparation method for pale rosin glyceryl ester, comprises the following steps:
A. zeolite is placed in to the lead nitrate solution that concentration is 0.1mol/L, soaks 1 day～2 days; Then take out, first at 80 DEG C～95 DEG C, dry to water content be 20%～30%, and then roasting 6 hours～8 hours at 300 DEG C～450 DEG C, the cooling substance A that obtains, for subsequent use;
B. 50 weight part～60 weight part rosin are put into reactor, nitrogen as protectant condition under, the air input of nitrogen is adjusted to 5ml/min～8ml/min, heating melts it completely, then the substance A that adds 1 weight part～2 weight part A step to make, stir and be warming up to 200 DEG C～220 DEG C, insulation reaction 1 hour～4 hours;
After C.B step, in described reactor, add 5 weight part～8 weight part glycerine, 0.5 weight part～0.8 part by weight of zinc oxide, 0.5 weight part～0.8 weight part Sulfothiorine and 0.4 weight part～0.6 weight part calcium propionate, stir, continue at 200 DEG C～220 DEG C insulation reaction 0.5 hour～1 hour; And then be warming up to 270 DEG C～280 DEG C, insulation reaction 2 hours～4 hours;
After D.C step, vacuumize and remove low-boiling-point substance, be then cooled to 200 DEG C～210 DEG C, discharging, obtains this pale rosin glyceryl ester.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention is by reducing as much as possible the oxidation of rosin, thereby makes the very shallow pale rosin glyceryl ester of color.
