The preparation method of 6-aminopenicillanic acid can effectively enhance the yield of the 6-APA, reduce production cost and enhance work and production efficiency.
Description
Technical field
The present invention relates to the preparation method of pharmaceutical raw material, specifically a kind of preparation method of 6-aminopenicillanic acid.
Background technology
6-aminopenicillanic acid is called for short 6-APA.With 6-APA is parent nucleus, can be prepared into the beta-lactam semisynthetic antibiotics with different side chain condensation.The beta-lactam semisynthetic antibiotics is widely used in clinical because of its determined curative effect, toxic side effect are little.Along with a large amount of uses of a series of beta-lactam semisynthetic antibiotics such as amoxycilline Trihydrate bp, Ampicillin Trihydrate, the market demand of its raw material 6-APA is also in continuous rising.
At present, prepare the method for 6-APA, generally comprise following steps: a, with the penicillin fermentation liquid be raw material after filtration, acidifying, butanols concentration extraction, make penicillin butyl ester extracting solution; B, with penicillin butyl ester extracting solution alkalization, make the penicillin salt aqueous solution, again with the butanols azeotropic, after filtration, washing, crystallization, drying be prepared into potassium salt of penicillin industry powder; C, be raw material,, obtain 6-APA through dissolving, enzymatic conversion, crystallization with potassium salt of penicillin industry powder.In this method processing step two times of crystallization is arranged.This just causes it, and yield losses is many in dual crystallisation process, product yield is low, also causes the waste of solvent, power and energy simultaneously, has strengthened production cost.Prepare 6-APA as stated above, the yield of its finished product is generally 81%.
Summary of the invention
Purpose of the present invention will provide a kind of 6-APA preparation method exactly, and this method production cost is low, the product yield height, and can be used for suitability for industrialized production.
The objective of the invention is such realization: the inventive method may further comprise the steps:
A, with penicillin fermentation liquid filtration, acidifying, butyl alcohol extraction concentrate, decolour penicillin butyl ester extracting solution (being called for short a time BA);
B, penicillin butyl ester extracting solution get the penicillin salt aqueous solution (being called for short RB) through the basic solution back extraction;
C, the penicillin salt aqueous solution carry out degreasing, washed resin post through resin column, are prepared into the degreasing penicillin salt aqueous solution;
After d, degreasing penicillin salt aqueous solution injection penicillin acylase retort are carried out enzymatic conversion, add the 6-APA crystal seed, growing the grain, crystallization, drying.
Processing parameter in a, the b step can carry out according to the processing parameter in the ordinary method.As in the prior art when preparation benzylpenicillin potassium (sodium) salt or the 6-APA, this acidifying all arranged, concentrate, technological processs such as degreasing, alkali lye back extraction.Basic solution can be salt of wormwood, yellow soda ash, but preferred salt of wormwood.
In the c step, the degreasing penicillin salt aqueous solution preferably carries out degreasing with the velocity flow of 200-400L/h through resin column, to remove residual butyl ester in the degreasing penicillin salt aqueous solution better; During the washed resin post, the volume that preferably makes the penicillin salt aqueous solution after the degreasing be the degreasing front volume 1.5-3 doubly; Can effectively prolong the work-ing life of penicillin acylase, further reduce production costs.
Employed resin is preferably ADS-18, AXT-33.Preferred ADS-18 can further guarantee the quality of resins exchange like this.
In the c step, in the retort of penicillin acylase, processing parameter preferably adds borate buffer by the 3%-10% of degreasing penicillin salt aqueous solution cumulative volume, carries out conversion reaction; Keep pH6.5-9.0 with ammoniacal liquor, temperature is controlled at 25-35 ℃, reaction times 90-120 minute; Conversion fluid is transferred pH0.5-2.5 with hydrochloric acid, and the 25%-50% that presses the conversion fluid volume adds organic solvent, stirs down at 5-20 ℃, leaves standstill 20 minutes, separates; Water is transferred pH1.5-2.7 with ammoniacal liquor, adds crystal seed and growing the grain 10 minutes, continues to transfer pH2.8-3.2 with ammoniacal liquor, adds crystallizing agent, continues to transfer to iso-electric point 4.0-4.3 with ammoniacal liquor, crystallization, drying.
The said organic solvent that gets in the c step can be selected butanols, butyl ester, methyl iso-butyl ketone (MIBK), methylene dichloride or toluene for use.But preferable methyl isobutyl ketone.
Crystallizing agent can be acetone, methyl alcohol or methyl iso-butyl ketone (MIBK), preferred acetone.
Crystallizing agent is as selecting acetone, methyl alcohol for use, and its add-on is counted 40-70% by the crystal solution volume, preferred 50-60%.
Crystallizing agent is as selecting methyl iso-butyl ketone (MIBK) for use, and its add-on is counted 5-30% by the crystal solution volume, preferred 10-20%.
Innovation part of the present invention has been to reduce the crystallization number of times of prior art in preparation 6-APA process, finish brilliant this processing step of penicillin Industrial Salt that forms thereby omit, the yield losses of effectively having avoided the penicillin crystallization to be caused, make the 6-APA yield improve 7～10%, reach more than 91%, significantly reduce the 6-APA production cost, also improved labour productivity simultaneously.
