Abstract
The present invention relates to a preparation process for 5'-nucleotide disodium, which is a preparation process for a strong fresh assistant, more specially to a simple and practical post-treatment process of a preparation process for 5'-nucleotide disodium. The preparation process comprises the following steps: a phosphorylation reaction is carried out by using nucleoside as raw material and using trialkyl phosphate as a solvent; a phosphorylation reaction liquid is hydrolyzed in a brine ice to obtain a hydrolysis liuqid containing trialkyl phosphate, water, phosphoric acid, hydrochloric acid, 5'-nucleotide, salt and a small amount of byproduct; the hydrolysis liquid stands to be naturally divided into a trialkyl phosphate layer and a water solution layer containing phosphoric acid, hydrochloric acid, 5'-nucleotide and a small amount of byproduct; the water solution layer with sodium hydroxide is neutralized until all of acid become salts, cooled and filtered to eliminate most of phosphate in order to obtain a water solution containing sodium chloride, 5'-nucleotide disodium, a small amount of byproducts and a small amount of phosphate; and the water solution is regulated by hydrochloric acid until the pH is 8, concentrated and crystallized to obtain 5'-nucleotide disodium.
Description
Technical field
The present invention is a kind of preparation technology of powerful fragrance adding agent, and what be specifically related to is a kind of preparation technology's of simple and easy to do 5 '-disodium 5 '-ribonucleotide aftertreatment technology.
Background technology
Nucleotide and derivative thereof be at medicine, food, and fields such as agricultural are widely used.5 '-inosine acid disodium and 5 '-Sodium guanylate all is powerful fragrance adding agents, and the two is used to mix monosodium glutamate, and its delicate flavour exceeds 40-100 doubly than general monosodium glutamate, and local flavor is better, obtains human consumer's welcome after this product puts goods on the market.Cytidylic acid disodium and uridine monophosphate disodium can be used for replenishing the nucleic acid in the cow's milk, to produce the humanized milk near human milk, can strengthen baby's immunizing power.
5 '-disodium 5 '-ribonucleotide all is very important in fields such as food and medicines as mentioned above, and its preparation technology has also had continuous development for many years, now looks back as follows:
With corresponding nucleosides and phosphorus oxychloride at pyridine, under the existence of alkaline mediums such as triethylamine, at certain polar organic solvent such as dimethyl formamide, dimethyl sulfoxide (DMSO) is reacted in the acetonitrile.1. reaction transfers to this hydrolyzed solution suitable substance P H value in finishing to fall back then, directly with active carbon column absorption, alkali lye wash-out; Or 2. use organic solvent in the insoluble organic solvent extracting of other water hydrolyzed solution, water transfers to suitable substance P H value, carries out separation and purification with anion-exchange resin column or active carbon column.(Gulland?et?al.，J.Chem.Soc.，1940；Tsumshima?Masaaki?et?al.，JP59167599，1984)。
2. 2 ' of nucleosides-and 3 '-position hydroxyl protection is got up; make solvent with trialkylphosphate; with phosphorus oxychloride reaction; deprotection again after the phosphorylated; salify adds ethanol crystallization is separated out, and recrystallization obtains 5 '-disodium 5 '-ribonucleotide (Masaharu Yoshikawa et al. again; US 3347846,1967).
3. with corresponding nucleosides and phosphorus oxychloride direct phosphorylated in trialkylphosphate; reaction is poured in the frozen water after finishing; the hydrolyzed solution neutralization is after anion-exchange column absorption; wash-out; condensing crystal obtains 5 '-disodium 5 '-ribonucleotide (Masaharu Yoshikawa et al.; US 3413282,1968).
4. using an alkali metal salt of inosine and guanosine, or contain the salt of one of them at least, mix and carry out phosphorylated, is solvent with the trialkylphosphate.Reaction is poured hydrolysis in the frozen water into after finishing, and uses the organic solvent extraction trialkylphosphate, and the aqueous solution adsorbs through active carbon column, wash-out, condensing crystal obtains 5 '-inosine acid disodium and 5 '-Sodium guanylate mixture (Shigemitsu Abe et al., EP 453597,1991).
5. corresponding nucleosides and trialkylphosphate reaction are earlier formed a kind of mixture, add phosphorus oxychloride then and carry out phosphorylated.Reaction finishes posthydrolysis, separates with active carbon column or ion exchange resin column and purifies, and last crystallization goes out product (Tomomi Ikemoto et al., Chem. Pharm. Bull., 1995; Akira Haze et al., CA2100027,1994).
1 is the acylation reaction technology of comparison classics in the above technology, and bad to the selectivity of 5 '-position, yield is affected.Use pyridine, triethylamine etc. are made catalyzer, and this compounds is water-soluble fabulous, therefore can produce serious water and pollute.The 2nd, earlier with 2 ' of nucleosides-and 3 '-position hydroxyl protection get up, carry out the phosphorylated of 5 '-position again, also want deprotection at last, step is loaded down with trivial details.Even found afterwards not 2 '-and 3 '-position hydroxyl protection get up; in the trialkylphosphate solvent system 5 '-and the phosphorylated of position also has very high selectivity (3 and 5), and therefore phosphorus acylation reaction all adopts in the trialkylphosphate solvent system and carries out in the production technique of present 5 '-disodium 5 '-ribonucleotide.
Although the technology of phosphorus acylation reaction has had very big improvement, post-reaction treatment technology is never too big change but: pour reaction solution in frozen water hydrolysis, directly adsorb with active carbon column then or after the hydrolysis, the alkali lye wash-out has a large amount of organic solvents to need further to handle in the effluent liquid; After the insoluble organic solvent extracting of water used in solvent taken out, separate with active carbon column or ion exchange resin column again and purify.Also have boric acid silicagel column partition method (Analytical Biochem., 1982), ion pair inverse permutation chromatography (Chem.Eng.Sci., 1992) in addition.But it is loaded down with trivial details that above method is all operated, time-consuming many, and separator column regeneration will produce a large amount of waste water.
