Description
Technical field
The present invention relates to a kind ofly carry out the pre-treatment processing method taking sherwood oil as solvent extraction gutta-percha again with acetic acid.
Background technology
The bark of eucommia is the distinctive precious economic tree of China, contains abundant gutta-percha in its bark, leaf and seed coat.The elastomeric rigid rubber of natural gutta-percha right and wrong, because its fusing point is low, be easy to processing, and has good electrical insulating property, is mainly used as the raw material of undersea cable, golf ball.In recent years, the study on the modification of gutta-percha has been obtained breakthrough: gutta-percha can vulcanize and makes high-elastic gonosome, also can control degree of crosslinking and produce novel material, as medical material, rubber item etc., can also make intermingling material with other material blend.So gutta-percha is a kind of natural macromolecular material, its unique rubber-mould duplicity to become the study hotspot in novel material development field.
Gutta-percha is white filament, is present in containing in cellula adhesiae, from plant, extract, through highly purified, decolouring after can obtain white solid.Gutta-percha dissolves in aromatic hydrocarbon and hydrochloric ether, also solubilized in the sherwood oil of heating, but be insoluble to ketone and alcohols polar solvent, in hot ethyl acetate, can melt swollen.Hydrofluoric acid and concentrated hydrochloric acid are inoperative to it, more stable in NaOH solution, but not resistance to nitric acid and hot sulfuric acid.At present, the extracting method of gutta-percha mainly contains solvent extraction method, alkali lye embathes method, microbial solid fermentation method etc.
Solvent extraction method is to utilize the high resolution of organic solvent to gutta-percha, improves gutta-percha polymer beads discongesting and dispersiveness in solvent, makes it through cell walls layer of fibers, spreads and stripping to liquid phase solvent.In the cell walls of natural bark of eucommia cell, contain the composition such as Mierocrystalline cellulose, xylogen, and iuntercellular exists pectin substance, these compositions are not soluble in the time of lixiviate, in addition solvent is limited to the run-inflation effect of cell walls, exist cell walls gutta-percha to be leached to the inhibition producing, reduced the stripping of dissolved form Folium glue wire.
In order to improve the solubility rate of gutta-percha from capsule, the fiber of the composition cell walls of must degrading improves its permeability.Alkali lye embathes method alkali hydrolysis method to be destroyed the xylogen of cell walls and collodion silk is exposed, but the NaOH that alkali lye extraction consumes amount is too large, and environmental pollution is serious; The Mierocrystalline cellulose of microorganism fermentation or enzymolysis process degradable bark of eucommia cell walls, makes cell walls become loose, is convenient to the stripping of glue, but exists fermentation time longer, the shortcoming that cost is high.Therefore, seek efficient, environmental protection, energy-conservation Gutta extraction operational path, for effectively utilizing, gutta-percha resource is significant.
Summary of the invention
The deficiency existing for solving Gutta extraction prior art, the inventor, through lot of experiments, invents a kind of method of extracting gutta-percha from plant tissue finally, and the method has efficiently, environmental protection, energy-conservation feature.
The present invention includes following step:
(1) pre-treatment of raw material, will propose the boiling of collagen material acetic acid solution and filter after 2-5 hour, and filter residue is for subsequent use.Wherein preferred acetic acid solution concentration range is that 70-98%, preferred boiling temperature scope are 100-150 DEG C, the mass volume ratio of preferably carrying collagen material and acetic acid solution is 1:6-1:12, pretreating effect the best under above-mentioned technical parameter, also be conducive to most the yield of follow-up Gutta extraction and raising gutta-percha, in mass volume ratio, the unit of quality is gram, and the unit of volume is milliliter.
(2) extraction of gutta-percha, the filter residue (1) being obtained taking sherwood oil as solvent extracts, and the freezing rear filtration of extracting solution obtains gutta-percha.
The most crucial technology of the present invention is to utilize acetic acid to carry out pre-treatment to carrying collagen material, destroys the cell wall structure in plant cell tissue, is conducive to the stripping of gutta-percha.Because pretreated acetic acid can reclaim and Reusability, thereby processing cost is very low; Again because pretreated acetic acid is processed and needed like that outer row unlike alkaline solution, thereby environment not being damaged, is the treatment process of a kind of low cost, environmental protection and practicality.
The mechanism that acetic acid treatment is conducive to Gutta extraction is: acetic acid is as a kind of small molecule solvent, xylogen in plant cell tissue is had to swelling action, at high temperature can enter in the macromolecular network structure of xylogen, under acid effect, xylogen macromole is hydrolyzed the xylogen fragment generating and is dissolved in acetic acid; Meanwhile, in xylogen hydrolysis process in leaching, the carbohydrate ingredient in plant tissue also issues unboiled water solution in sour effect; On the other hand, by acetic acid treatment, the component strippings such as the chlorophyll in plant tissue, the purity that improves gutta-percha is high.Therefore, destroy cell walls by acetic acid boiling collodion silk is exposed, be conducive to the stripping of glue.
Carry out pre-treatment with acetic acid and also obtained unexpected and very good technique effect.Border measuring and calculating factually, by the pretreated collagen material of carrying of acetic acid, adopts soxhlet extraction method to extract 6 hours taking sherwood oil as solvent, the extraction yield of gutta-percha can improve 20-40%, and effect is very remarkable.
Compared with prior art, beneficial effect of the present invention is also: present method is especially applicable to extracting content of lignin higher gutta-percha raw material, and as Eucommia shell, Cortex Eucommiae etc., have efficient, environmental protection, energy-conservation feature.
