Description
Technical field
The present invention relates to a kind of oxide purification method, specifically a kind of environmental protection oxide purification method of montanin wax.
Background technology
Montanin wax from brown coal, extracts with organic solvent the waxy product obtained under certain condition, because its irreplaceable good characteristic is widely used in the fields such as daily use chemicals, casting, automobile.But make it be chocolate due to the material such as tricyclic diterpene, pentacyclic triterpene hydro carbons of aromizing in brown coal waxy stone, even if the montanin wax color after degreasing is still comparatively dark, this have impact on its range of application greatly.Therefore how to remove the oxide purification of dark material in montanin wax and become the research emphasis in montanin wax field, at present comparatively ripe and effective decoloring method is still chromic anhydride, chromic acid and the method for oxidation of dichromic, but there is many defects and deficiency, first be that chrome liquor used is rich in heavy metal chromium element, chromium waste liquid industry after oxidation generally adopts electrolytic regeneration process, but the incompleteness in view of technology makes its transformation efficiency can not reach absolutely (general peak rate of conversion is about 80 percent), so in fact still will constantly add new chrome liquor in whole production chain, and electrolyzer cost is high and highly confidential, there is no public sale related products at present, therefore also limit wideling popularize of this method, in addition the sulfuric acid lotion after using and water lotion will through complicated dialysis recyclings, and this has increased the weight of cost again indirectly, it is crucial that chromium drift products obtained therefrom more or less has the remnants of chromium element, which has limited its application in the high-end field such as daily use chemicals, food.Actively advocate today of construction " amphitypy society " in country, the cry of montanin wax Chrome-free oxide purification grows to even greater heights.Therefore, study hotspot and the development trend that new environmental protection oxidation system becomes this field is sought.
At present about the domestic article of montanin wax Chrome-free oxide purification and patent only a case each, Lee is precious just to be waited (" Li Baocai etc. the nitric acid oxidation of montanin wax refines [J]. Jiangxi humic acids; 1987; (1): 29-35. ") once attempted nitric acid oxidation and refine montanin wax, consequently product can not decolour completely, and easily cause environmental pollution, therefore industrialization could not be realized.Although application number 201010535750.0 also discloses a kind of oxidative decoloration process for purification of montanin wax of Chrome-free, but it still also exists very large limitation: it adopts hydrogen peroxide and ammonia water mixture to be main drift agent, but repeatedly find after repeatability checking to there will be obvious saponification reaction in the method experimentation, montanin wax can become spumescence and expand, if solvent slightly adds and too fastly can cause vigorous splash, it is larger that operation controls difficulty, and it is excessive to add ammoniacal liquor pungent odour, and final effect exists misleading, because the wax after saponification is milky really, but more than higher than montanin wax fusing point (about about 80 DEG C) temperature, its final color is still darker, which illustrate chromophoric group or structure that the method can not destroy montanin wax inside effectively.And hydrogen peroxide very easily to decompose under the high temperature conditions when not adding stablizer be basic general knowledge, it slowly adds drift agent and stirs 1-4 hour under adopting 90-120 DEG C of condition, if shift decomposed drift agent not in time, the relative concentration adding drift agent after certainly will causing is more and more less and hydrogen peroxide retention time is too short, so have a strong impact on its oxidation effectiveness.The problem of core is the acid hard montanin wax of light color that this method can not obtain real meaning, is more not suitable with the deep processing of montanin wax.Therefore the effective ways of non-chromium system oxide purification montanin wax are not still found.
Generally believe that a kind of SYNTHETIC OPTICAL WHITNER can only optionally some chromophoric group of attack, certain limit is existed to the raising of whiteness, and SYNTHETIC OPTICAL WHITNER also may generate new chromophoric group while the original chromophoric group of destruction.If several SYNTHETIC OPTICAL WHITNER destroying chromophoric group function different are combinationally used, so just can occur: can not only destroy original chromophoric group but also newborn chromophoric group can be made to become achromatic structure, such whiteness certainly will improve greatly.Apply in montanin wax oxide purification about the common bleaching of Peracetic Acid and hydrogen peroxide at present and have no report.
