Description
Technical field
Technical scheme of the present invention relates to the crystallization preparation method of the compound of hydroxyl, is a kind of method of extracting Xylitol from Xylitol mother liquor specifically.
Background technology
Xylitol is a kind of polyvalent alcohol that contains five carbon atoms and five hydroxyls, is widely used in food, medicine, papermaking, chemical industry.CN 03111433.4 " a kind of method of producing Xylitol with made from bracteal leaf of corn " and CN 03110852.0 " extract the method for wood sugar and Xylitol from agricultural crop straw " and actual production situation shows that the raw material of domestic production Xylitol mainly is corn cob, leaf or agricultural crop straw at present.These raw materials by acidification hydrolization, neutralization, reduction vaporization, decolouring, ion-exchange, hydrotreatment, concentrate, operations such as crystallization, separation, make xylitol crystal and mother liquor.Xylitol mother liquor is the byproduct after Crystallization Separation goes out finished product, but 1 ton of finished product by-product Xylitol mother liquor per ton.It is isabelline that Xylitol mother liquor is, impure more, and purity is low, viscosity is big, wherein except that major part is Xylitol, also contains a spot of arabitol, sorbyl alcohol, N.F,USP MANNITOL one class fusel.The past Xylitol mother liquor can not utilize again and can only discharge.Valuable resource has not only been wasted in the discharging of Xylitol mother liquor, also causes the serious environmental pollution.Be to realize the utilization again of Xylitol mother liquor, many investigators are arranged all in the utilization of research Xylitol mother liquor and extractive technique again.
Generally contain 20～60% Xylitol in the Xylitol mother liquor, also have 15～30% fusel.The modal purifying technique that has earlier is that Xylitol mother liquor is carried out reduction vaporization, and the Xylitol crystallization after will evaporating then leaches.This method energy consumption is big, quality instability, enhydrous rate height.Afterwards, CN 1162384C proposed, and contacted with particulate Xylitol in being suspended in gas with xylitol solution, and dried feed acquisition crystallite also is adjusted to the agglomeration product with raw material.The preparation apparatus that this arts demand is specific is invested bigger.Zhao Guanghui etc. (using chemical industry, 2005 3 phases) propose the processing method with PCR 642 resin isolation purifying xyloses alcohol mother liquor.Zhang Suoqin etc. (Jilin University's natural science journal, 10 phases of calendar year 2001) have inquired into the processing method of carrying out effective constituent in the chromatographic separation Xylitol mother liquor with the SM-19 resin.Ying Guoqing etc. (Chinese Journal of Pharmaceuticals, 2002 3 phases) have proposed the remaining wood sugar in the mother liquor is degraded to corresponding acid and salt, and the reconcentration crystallization obtains the technology of xylitol crystal.(Hebei chemical industry such as Xu Yong, 2003 3 phases) propose, at first Xylitol mother liquor is used the thickening of decompression method, adding crystal seed placed after 4 days, add and placed again 4 days after ethanol stirs, with settlement separate Xylitol ethanol liquid underpressure distillation again, a part obtains secondary mother liquid, and a part is isolated xylitol crystal after crystallization is bred.Slide is steamed in above-mentioned decompression heating, the resin chromatography separation method all needs special-purpose production unit and cleaning equipment.
In a word, more than existing processing method more complicated or need specific preparation apparatus all, need a large amount of middle process processes come controlled step, thereby have the shortcoming that technology is tediously long, energy consumption is high, product yield is low.
Summary of the invention
Technical problem to be solved by this invention is: a kind of method of extracting Xylitol from Xylitol mother liquor is provided, and this method has the advantage that technology is simple, energy consumption is low, product yield is high.
The present invention solves this technical problem the technical scheme that is adopted: Xylitol mother liquor is warmed to 90～110 ℃, be incubated 1～2 hour, solution evaporation is concentrated, cool to 40～55 ℃ then, add weight and be 0.01% food grade potassium sorbate or Sunmorl N 60S of Xylitol mother liquor weight, after stirring, cool to room temperature left standstill 3～7 days, after treating that solution becomes suspension liquid, enter the vacuum filtration machine and carry out suction filtration, obtain the xylitol crystal of 95% above purity.
In aforesaid method, when adding 0.01% the food grade potassium sorbate or Sunmorl N 60S that weight is Xylitol mother liquor weight, the dehydrated alcohol of X% that adds volume and be the Xylitol mother liquor volume is or/and volume is that the glycerine of Y% of Xylitol mother liquor volume is or/and weight is the xylitol seed crystals of the Z% of Xylitol mother liquor weight, here, 0＜X%≤5%, 0＜Y%≤2%, 0＜Z%≤1%.
The invention has the beneficial effects as follows: owing to added 0.01% food grade potassium sorbate that weight is Xylitol mother liquor weight or Sunmorl N 60S in the methods of the invention as promotor, the effect of promotor mainly is the seed surface growth that promotes that xylitol crystal is forming.Particularly when adding 0.01% the food grade potassium sorbate or Sunmorl N 60S that weight is Xylitol mother liquor weight, the dehydrated alcohol of X% that adds volume and be the Xylitol mother liquor volume is or/and volume is that the glycerine of Y% of Xylitol mother liquor volume is or/and weight is the xylitol seed crystals of the Z% of Xylitol mother liquor weight, here, 0＜X%≤5%, 0＜Y%≤2%, 0＜Z%≤1% have just quickened the speed of growth of xylitol crystal more.Thereby the product yield height that the inventive method obtains facts have proved more than the extraction rate reached to 70% of extracting Xylitol from Xylitol mother liquor; The energy consumption of the inventive method is low, facts have proved that the energy consumption of extracting the unit weight Xylitol reduces by 50%; The inventive method technology is simple, mainly has only heating evaporation, adds promotor, stirs cooling and four operations of vacuum filtration.
