Abstract
The invention discloses a preparation method of pale rosin methyl ester, relating to the technical field of rosin deep processing. The method comprises the following steps: adding rosin methyl ester into a distilling apparatus, and inspecting the air tightness of the distilling apparatus; and after the air tightness of the distilling apparatus is perfect, vacuumizing to 50-250 pa, distilling, and collecting the fraction. The pale rosin methyl ester prepared by the vacuum distillation method can remove most impurities in the rosin methyl ester. The obtained product has the advantages of low cost, favorable properties and wider applicability.
Description
Technical field
The present invention relates to Colophonium deep process technology field, the preparation method of a kind of pale rosin methyl ester.
Background technology
Colophonium is the Renewable resource of China's abundant, and annual production reaches more than 60 ten thousand tons, ranks first in the world.Colophonium processization
Learn modification and can obtain a series of deep processed product, the every field being widely applied in daily life, these deep processed products
Value ratio raw material Colophonium improve decades of times.
Abalyn is a kind of Colophonium deep processed product being in a liquid state at normal temperatures, by Colophonium with methanol in certain temperature
Prepare with carrying out esterification under pressure condition.Due to the application performance that itself is excellent, abalyn can be used as surface and lives
Property agent, viscosifier are applied to plastics, rubber, coating and gluing industry.
Along with the further development of science and technology, the application of abalyn is also continuously available expansion: abalyn can conduct
Lasting agent is applied to the production of essence, perfume and depilatory cream, is applied to sensitive material, metal as solvent resistant and anti-chemical coating
Preparation with plastics;The production of binder, plaster and scalp pomade it is applied to as chemical addition agent;It is alternatively arranged as microscopical immersion oil agent
And food fixastive and food additive.But, these products are more and more higher to the prescription of abalyn, especially should
When the health grade product such as depilatory cream, fixastive, food additive, it is desirable to it possesses lighter color, higher purity
And relatively low abnormal smells from the patient.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of pale rosin methyl ester, this preparation method can solve Colophonium
The problem that methyl ester product colour is deeper.
In order to solve the problems referred to above, the technical solution used in the present invention is:
The preparation method of this pale rosin methyl ester is: added by abalyn in distilling apparatus, checks the airtight of distilling apparatus
Property, after confirming that device air-tightness is intact, it is evacuated to 50 handkerchiefs~250 handkerchiefs, is heated to 212 DEG C~220 DEG C, be incubated distillation 1
Hour~2 hours, collect fraction, i.e. obtain pale rosin methyl ester product.
In technique scheme, more specifically technical scheme is it may also is that the rotating speed of distilling apparatus is 20 revs/min~60
Rev/min.
Further, after abalyn is added distilling apparatus, connect receiving flask, vacuum tube, open condensate cooler
Cooling water, then adjusts alembic rotating speed, can carry out air-leakage test after evacuation.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the present invention uses the method for vacuum distilling to prepare pale rosin methyl ester fat, and the method can remove in abalyn does not joins
With the rosin resin acid monomers being esterified, neutral substance etc., products obtained therefrom is of light color, acid number is low, purity is high, viscosity is bigger.
2, the inventive method technique is simple, and production cost is relatively low.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1
The preparation method of the present embodiment pale rosin methyl ester is: is put in 5L revolving bottle by 2500 grams of abalyns, connects and connect
By bottle and with vacuum inspection, confirm system air-tightness intact.Distallation systm is evacuated to 50Pa, checks confirmation system air-tightness
After intact, beginning to warm up distillation, by room temperature to 212 DEG C~220 DEG C, insulation distillation 1 hour, stop distillation, this fraction is i.e.
For pale rosin methyl ester.
The present embodiment pale rosin methyl ester is pale yellow transparent thick liquid, acid number 2.2mg/g, color 1(ferrum cobalt color), viscous
Degree (25 DEG C) is 3500mp.
Embodiment 2
The preparation method of the present embodiment pale rosin methyl ester is: is put in 5L revolving bottle by 2500 grams of abalyns, connects and connect
By bottle and with vacuum inspection, confirm system air-tightness intact.Distallation systm is evacuated to 200Pa, checks that confirmation system is airtight
Property intact after, begin to warm up distillation, by room temperature to 212 DEG C~220 DEG C, insulation distillation 1.5 hours, stop distillation, this evaporates
Divide and be pale rosin methyl ester.
The present embodiment pale rosin methyl ester pale yellow transparent thick liquid, acid number 2.1mg/g, color 1-(ferrum cobalt color), viscous
Degree (25 DEG C) is 3450mp.s.
Claims (3)
1. the preparation method of a pale rosin methyl ester, it is characterised in that preparation process is: abalyn is added distilling apparatus
