Description
Technical field
The method that the present invention relates to a kind of to extract succinate from succinic acid fermentation liquor, belongs to fine chemistry industry skill
Art field.
Background technique
Currently, the production of succinic acid mainly uses chemical method of the butane through maleic anhydride, this method is at high cost, seriously
Hinder the large-scale production of succinic acid.Compared with chemical method, using cheap reproducible resource as the anaerobic biological process of raw material
Production succinic acid has the characteristics that Atom economy is high, process is environmentally protective and can realize low-carbon emission reduction, receives the U.S., day
Originally, the extensive concern of the National Academies and industry such as South Korea and China.Since there are two active carboxylic acid groups for tool, succinic acid can
Important succinate is generated so that esterification occurs with alcohol, and then synthesizes light stabilizer, high-grade paint, fungicide, medicine
Intermediate is hydrogenated to butanediol.Synthetic method in relation to succinate has been disclosed in many documents.For example, Chinese
Patent of invention 201310120279.2 changes macropore styrene resin in such a way that chloro, alkali earth metal sulfate are modified
Property, modified resin has good heat-resistant stability and activity for succinate synthesis.Li Xiang etc. uses 3A molecule
Adsorption dewatering technology is sieved, is Material synthesis succinic acid two by catalyst, succinic acid and isopropanol of cation exchange resin NKC-9
Isopropyl ester (daily chemical industry, 546-549 pages of 10 phases of volume 44 in 2014).9 kinds of differences are prepared for Zhao using two-step method along grade
Lewis acidic ion liquid, and systematically investigated its catalytic performance to succinic acid and isopropanol esterification, obtained
Diisopropyl ester amber acid yield is reaction result (Journal of Chemical Industry and Engineering, 2 phase 561- of volume 65 in 2014 of 88.9% and esterification yield 92.7%
Page 569).Aqueous solution of such as the above succinate synthetic method reported in the literature with succinic acid or containing succinic acid is made
It for raw material, however obtains succinic acid sterling and needs cumbersome process, for biology base succinic acid.
The separation of biology base succinic acid mainly includes calcium salt method, electroosmose process, ammonium salt crystallization method, ion-exchange and film point
From method, these methods can be used alone or in combination to reach satisfactory separating-purifying effect.United States Patent (USP) US5168055
It reports and is directly added into calcium salt in fermentation liquid, form calcium succinate precipitating with succinic ion, then filtering precipitating, use
The method that the mode that sulfuric acid acidification, crystallization are precipitated obtains succinic acid product.US5143834, JP2283289 and JP2944157 are adopted
It is separated with electrolytic method and obtains succinic acid, the succinate solution of low concentration is specifically subjected to electrolysis, makes fourth two
The supersaturated solution and lye of acid.Wherein, the lye isolated may return to fermentation vat for neutralizing succinic acid, realize back
With.However, the electrolysis process initial investment and operating cost are higher, and are only suitable for being electrolysed the monovalent salt fermentation liquid of succinic acid,
To succinic acid divalent salts fermentation liquid and it is not suitable for.Yun Suk Huh etc. is using expensive trioctylamine-n-octyl alcohol solution complexometric extraction
Succinic acid, which may will affect the quality of succinic acid using the trioctylamine being more toxic, and recovered solvent makes again
Albumen therein, pigment (Process Biochemistry, 2006 volume 41 page 1461-1465) need to be removed before.
US5958744 is disclosed is added ammonium hydroxide and sulfuric acid adjusting pH value, subsequent progress coarse crystallization and recrystallizing methanol in fermentation liquid
The method for obtaining succinic acid.In the patent, the ammonium sulfate that ammonium hydroxide and sulfuric acid reaction generate thermally decomposes under 300 DEG C of hot conditions can
Ammonium hydroxide and sulfuric acid are recycled, but unfriendly to environment using toxic methanol in recrystallization process.US20090234160
The method that succinic acid is obtained from the succinate solution comprising alkali metal is reported, the technology utilization alkali metal sulfates and fourth
The different feature of diacid solubility with temperature variation tendency, is added sulfuric acid in alkali metal succinate solution, and high temperature crystallization is heavy
Partial alkaline-metal sulfate is isolated in shallow lake, and then low-temperature precipitation removes succinic acid crystal crude product, and last succinic acid crude product dissolution is lived
Property carbon decoloring, recrystallization and it is dry obtain succinic acid product, however, relatively complicated, the alkali metal sulphur of the step of being disclosed in the patent
Hydrochlorate may will affect the quality of succinic acid product.
