Abstract
The invention discloses a preparation method of light-color hydrogenated rosin methyl ester and relates to the technical field of rosin deep processing. The method comprises the following steps: adding hydrogenated rosin methyl ester into a distillation device; checking the airtightness of the device; vacuumizing to 50-200Pa; heating to 210-220 DEG C; performing heat-preserving distillation for 1-1.5 hours; and collecting the fraction to obtain the product. The method disclosed by the invention can eliminate the rosin resin acid monomer, neutral substances and the like not participating in esterification in the hydrogenated rosin methyl ester; and the obtained product has the advantages of light color, low acid value, high purity and relatively high viscosity.
Description
Technical field
The present invention relates to Colophonium deep process technology field, the preparation method of a kind of light color hercolyn D.
Background technology
Hercolyn D is a kind of Colophonium deep processed product being in a liquid state at normal temperatures, hydrogenated rosin and methanol carry out esterification under the conditions of certain temperature and pressure and prepare.Due to the application performance that itself is excellent, hercolyn D can be used as surfactant, viscosifier are applied to plastics, rubber, coating and gluing industry.
Further development along with science and technology, the application of hercolyn D is also continuously available expansion: hercolyn D can be applied to the production of essence, perfume and depilatory cream as lasting agent, is applied to the preparation of sensitive material, metal and plastics as solvent resistant and anti-chemical coating；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 hercolyn D, when being applied especially to 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 light color hercolyn D, the preparation method of this light color hercolyn D can solve the problem that hercolyn D color 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 light color hercolyn D comprises the following steps: added by hercolyn D in distilling apparatus, distilling apparatus is carried out air-leakage test, after confirming that device air-tightness is intact, it is evacuated to 50 handkerchiefs～200 handkerchiefs, it is heated to 210 DEG C～220 DEG C, insulation distillation 1 hour～1.5 hours, collects fraction, i.e. obtains light color hercolyn D product.
In technique scheme, more specifically technical scheme is it may also is that the rotating speed of distilling apparatus is 28 revs/min～80 revs/min.
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 that distilling apparatus is evacuated to 50 handkerchiefs～200 handkerchiefs, it is possible to removing in hercolyn D and have neither part nor lot in the rosin resin acid monomers of esterification, 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 light color hercolyn D is: 2500 grams of hercolyn Ds put in 5L revolving bottles, connect receiving flask and with vacuum inspection, confirm that system air-tightness is intact.Distallation systm being evacuated to 100Pa, after checking that confirmation system air-tightness is intact, begins to warm up distillation, by room temperature to 210 DEG C～220 DEG C, insulation distillation 1.5 hours, stop distillation, this fraction is light color hercolyn D product.
The present embodiment product is pale yellow transparent thick liquid, acid number 2.0mg/g, color 1-(ferrum cobalt color), viscosity (25 DEG C) 3950mp.s.
Embodiment 2
The preparation method of the present embodiment light color hercolyn D is: 2500 grams of hercolyn Ds put in 5L revolving bottles, connect receiving flask and with vacuum inspection, confirm that system air-tightness is intact.Distallation systm being evacuated to 50Pa, after checking that confirmation system air-tightness is intact, begins to warm up distillation, by room temperature to 210 DEG C～220 DEG C, insulation distillation 1 hour, stop distillation, this fraction is product.
The present embodiment product is pale yellow transparent thick liquid, acid number 1.6 mg/g, color 100(Ha Sense), viscosity (25 DEG C) 3550mp.s.
Claims (2)
1. the preparation method of a light hercolyn D, it is characterized in that comprising the following steps: added by hercolyn D in distilling apparatus, this device is carried out air-leakage test, after confirming that this device air-tightness is intact, this device is evacuated to 50 handkerchiefs～200 handkerchiefs, is heated to 210 DEG C～220 DEG C, insulation distillation 1 hour～1.5 hours, collect fraction, i.e. obtain light color hercolyn D product.
The preparation method of light color hercolyn D the most according to claim 1, it is characterised in that: the rotating speed of described distilling apparatus is 28 revs/min～80 revs/min.
