Abstract

The invention relates to a process method for extracting dihydroartemisinin from waste mother liquor in production of dihydroartemisinin. The process method is characterized by comprising the following steps of: a, concentration: mixing all waste mother liquor in production, and concentrating at 60 DEG C until the volume is 1/20 of the original volume; b, desalting: quickly cooling, adding ice water in an amount which is about 1/5 of the volume of the mother liquor, performing centrifugal filtration with stirring, discarding filtrate, and repeating the step for four times; c, extraction: adding pure water in an amount which is about 10 times weight of coarse crystals, adding equivoluminal chloroform, extracting for three times, concentrating until crystals are separated out, cooling to 0 DEG C for crystallization, and repeating the step once more; d, salt leaching: putting the crystals into a centrifuge, rotating the centrifuge at a speed of 200 rpm, adding ice water in an amount which is 10 times weight of the crystals, performing centrifugal filtration, discarding filtrate, adding a small amount of methanol before the rotation is stopped, dissolving a dry product by using an aqueous solution of NaOH, and controlling the pH value to be 7-9; and e, drying and packaging: performing vacuum drying at the temperature of between 50 and 60DEG C, and performing vacuum packaging. By the process method, production cost is saved, and enterprise benefit is improved.

Description

From produce the dihydroarteannuin waste mother liquor, extract the processing method of dihydroarteannuin
Technical field
The present invention relates to from produce the dihydroarteannuin waste mother liquor, extract the processing method of dihydroarteannuin.
Background technology
In the process of utilizing the synthetic dihydroarteannuin of Artemisinin, can produce a large amount of waste mother liquors, be in the preparation feedback of solution with methyl alcohol, the main component of waste mother liquor is a methyl alcohol.Wherein except a large amount of methyl alcohol and inorganic salt, also contain the dihydroarteannuin of certain content.If utilize traditional technology; Can't obtain the high dihydroarteannuin of purity; In the technical study of preparation dihydroarteannuin; Domestic a lot of manufacturing enterprise just abandons after with Methanol Recovery, does not further separate dihydroarteannuin, and this must cause the waste of resource; Utilize the waste mother liquor that produces in the production process; Produce the dihydroarteannuin rate, directly related enterprise production cost does the high performance of enterprises.
Summary of the invention
The problem that the present invention will solve provides a kind of processing method of from produce the dihydroarteannuin waste mother liquor, extracting dihydroarteannuin.
The present invention extracts the processing method of dihydroarteannuin from produce the dihydroarteannuin waste mother liquor, it is characterized in that including following steps:
A. concentrate: merge all waste mother liquors in the production, under 60 ℃ of conditions, be concentrated into 1/20 of original volume;
B. desalination: the cooling of fast speed, add the frozen water of mother liquor volume about 1/5, stir centrifuging, discard filtrating, repeat four times;
C. extraction: add the pure water of 10 times of about coarse crystallization, add isopyknic chloroform extraction again three times, be concentrated into crystal and separate out, be cooled to crystallization under 0 ℃ of condition; Recrystallization once again;
D. the desalinization of soil by flooding or leaching: crystal is put into whizzer, rotate whizzer with 200 rev/mins speed, add the frozen water of 10 times of crystallizations simultaneously, centrifuging discards filtered liquid; Before stopping operating, add a little methyl alcohol; With NaOH aqueous solution dissolving dry product, control ph value is 7-9;
E. baking is wrapped: vacuum-drying under 50 ℃ of-60 ℃ of conditions, vacuum packaging.
The present invention extracts the processing method of dihydroarteannuin from produce the dihydroarteannuin waste mother liquor, desalting through pure water adds the centrifugal technology that desalts, and dihydroarteannuin solution saves production cost in the extraction waste mother liquor, does the high performance of enterprises.
