Abstract
The invention discloses a method for producing rosin by using naturally fallen turpentine, and belongs to the technical filed of deep processing of rosin. The method comprises the following steps: putting a raw material naturally fallen turpentine in a reaction kettle, adding xylene, turpentine, oxalic acid and water, stirring to completely dissolve the raw material naturally fallen turpentine, filtering to remove filter residues, putting the obtained filtrate in a clarifying pot, clarifying, separating, putting the above obtained fat liquor in a distillation kettle, and distilling to obtain a residual kettle liquid which is the rosin product. The yield and the purity of the rosin product prepared in the invention are above 80% and above 85% respectively.
Description
Technical field
The invention belongs to rosin production technical field, relate in particular to a kind of method of utilizing fallen rosin to produce rosin.
Background technology
Rosin is a kind of natural resin, is the physiological metabolism product producing in pine genus tree vital movement process, is a kind of oil-containing natural resin, is colourless, transparent viscous liquid.Rosin is mainly gathered in the pine resin road of pine tree, has fragrance and the bitter taste of pine tree, and its main component is resinous acid, lipid acid, unsaponifiables.Rosin is after processing, and the nonvolatile terpenes solid product obtaining is rosin.
Wherein, Pinus seeds can be because being endangered by disease worm, and xylem sustains damage, and wound flows out a lot of rosin, and these rosin accumulate over a long period, and gather Pinus seeds root, and we are called fallen rosin by this class rosin conventionally.
Fallen rosin being processed in the process of rosin, often due to the impurity participating in and the impurity itself containing, make the rosin product recovery rate that makes in the time collecting fallen rosin, purity is all too low, is difficult to reach the requirement in market.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of method of utilizing fallen rosin to produce rosin, and the method has solved the rosin product yield that prior art makes, and purity is all too low, is difficult to reach the problem of market demands.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
It comprises the following steps:
A. 30 weight part～45 weight part raw material fallen rosin are put into and melted still, under agitation condition, add 3 weight part～5 weight part dimethylbenzene and 1 weight part～3 weight part turps, 0.1 weight part～0.3 weight part oxalic acid and 8 weight part～12 weight parts waters, at 60 DEG C～80 DEG C, stir, raw material fallen rosin is melted completely, in whipping process, the steam producing is recycled simultaneously;
After B.A step, remove by filter filter residue, obtain first fat liquid will put into clarifying kettle, clarification, separate and obtain second fat liquid, then again this second fat liquid is put into clarifying kettle, again clarify, separate and obtain San road fat liquid;
After C.B step, Jiang tri-road fat liquid are put into still kettle, 150 DEG C～180 DEG C distillations 1 hour～3 hours, reclaim solvent, and the residual still liquid obtaining is rosin product.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The rosin product yield that the present invention makes is more than 80%, and purity is more than 85%.
