Description
Technical field
The present invention relates to technical field of chemical medicine, and in particular to the preparation method of surfactant.
Background technology
Because surfactant has excellent application performance, have in industrial production and daily life extensive
Application.All the time, people never stopped the R and D to novel surfactant.Particularly raw material sources are wide
It is general, good biocompatibility, the exploitation of the unique surfactant of function is always one of focus of research.
Chitosan oligosaccharide is called Chitosan poly oligosaccharide, chitosan oligomer, is through special biological enzyme technology by chitosan(Also there is useization
Learn degraded, the report of microwave degradation technology)A kind of obtained degree of polymerization of degrading oligosaccharide product between 2~20, molecular weight≤
3200Da, is the water-soluble preferable, low molecular weight product that function is big, bioactivity is high.It has chitosan unexistent
Higher solubility, is dissolved in water entirely, easily many unique functions such as absorbs by organism, it act as the 14 of chitosan
Times.Chitosan oligosaccharide is unique positively charged cation basic amine group oligosaccharide in nature, is animal fiber element.At present both at home and abroad
It is more to chitin modified surfactant research, chitosan anionic, cationic and the amphoteric surfactants of preparation
Agent all has been reported that.Such as chitosan and the alkyl glycidyl ether of different length carbochain can synthesize a series of new in the basic conditions
Type amphoteric surfactant;By chitosan graft glycidyl dodecyldimethylamine ammonium chloride, further sulfonation is introduced
Sulfonic group and synthesized a kind of extremely strong high molecular surfactant of hygroscopicity;Utilize chitosan and 2,3- epoxies
Ammonium chloride reacts, and can synthesize HACC cationic surface active agent.Also have chitosan in addition
The report for the surfactant being combined with organosilicon.
Amino acid is the basis for constituting protein, is the primitive material for constituting life.Usual amino acid surface activity
Agent mainly introduces long chain fatty acyl on the amino of amino acid, then neutralizes into and corresponding surface-active is can obtain after salt
Agent.Conventional amino acid has methyl amimoacetic acid, glutamic acid, serine, alanine, propylhomoserin, leucine etc. is picked, wherein with methyl amimoacetic acid, paddy
Propylhomoserin is the most commonly used.Used aliphatic acid is divided into saturation and unsaturated two kinds, such as oleic acid, oleic acid, cocinic acid, palm oil
Acid, hard fatty acids, octanoic acid, capric acid etc..
Because surfactant can be aligned in incompatible two-phase interface, this causes surfactant being related to two-phase
Some properties at interface(Identification, catalysis, the sustained release performance at such as interface etc.)Aspect has advantageous advantage.Shell gathers
Sugar surfactant has certain filming performance, but poor to the specific effect of Cucumber;Amino acid surfactant
There is certain specific effect to Cucumber(Such as some metal ions), but film forming is relatively weak.In addition, being lived using surface
Property agent molecule in the performance of hydrophobic side chain regulation surfactant be also one of key content in surfactant research.
The content of the invention
The defect existed for both the above surfactant, the present invention proposes a kind of water-soluble preferably N-(N '-oleoyl
Glycyl)- chitosan oligosaccharide sodium sulfonate.
The N- of the present invention(N '-oleoyl glycyl)The molecular structural formula of-chitosan oligosaccharide sodium sulfonate is as follows:
Wherein n=6~15.
The surface-active available amino acid of the amino acid chitosan oligosaccharide surfactant of good water solubility of the present invention is different
Hydrophobic side chain be finely adjusted.
Product of the present invention is a kind of with good biocompatibility, the adjustable environmental protection of efficient, nontoxic, surface-active
Surfactant, such surfactant has good filming performance, and property is gentle, except with general surfactant
Outside feature, it may also be used for fat-soluble medicine is sustained the structure of microbody, extensive in field of medicaments application prospect.
It is another object of the present invention to propose the preparation method of above product.
The present invention comprises the following steps:
1)By n-hydroxysuccinimide(NHS)And dicyclohexylcarbodiimide(DCC)Mixed with the DMF solution of oleic acid anti-
Should, obtain filtrate;
2)Glycine and potassium carbonate are dissolved in the water, above-mentioned filtrate is added dropwise under the conditions of ice-water bath, drip it is rearmounted at room temperature
Reaction, is made N- acyl amino acid solutions;
3)The pH value of N- oleoyl glutamine solutions is adjusted to after neutrality and chitosan oligosaccharide, 1- (3- dimethylamino-propyls) -3- ethyls
Carbodiimide hydrochloride and n-hydroxysuccinimide mixing are reacted, and generate N-(N '-oleoyl glycyl)- chitosan oligosaccharide;
4)By N-(N '-oleoyl glycyl)- chitosan oligosaccharide is swelled rear and chlorosulfonic acid with DMF and carries out sulfonating reaction, and reaction will after terminating
The pH value of reaction solution is adjusted to neutrality, centrifugation, takes supernatant to be dialysed with bag filter;
5)By the dialysate filter in bag filter, filtrate is obtained, it is freeze-dried, obtain N-(N '-oleoyl glycyl)- chitosan oligosaccharide sulphur
Sour sodium.
The reaction equation of the present invention is as follows:
Wherein n=6~15.
It is an advantage of the invention that:Synthetic reaction is simple, and reaction condition is gentle, and high income, reaction can be quantified.Due to first step reaction
NHS is used(N-hydroxysuccinimide)NHS is discharged after activation aliphatic acid, with amino acid couplings, is coupled with chitosan oligosaccharide
When can be directly added into aqueous condensation reagent EDC(1- (3- dimethylamino-propyls) -3- ethyl-carbodiimide hydrochlorides)Just can be in water
It is middle to complete reaction, therefore second step reacts(With amino acid couplings)Three-step reaction can be carried out without separation.It so can be achieved one
Pot method reaction, greatlys save reaction cost.
Reaction alkali selection potassium carbonate used, this is due to that the carboxylic acid of potassium carbonate and glycine acts on forming saleratus,
Reaction need not add alkali again in addition, so as to simplify technique.
The present invention by the pH value of N- oleoyl glycine solutions be adjusted to after neutrality with chitosan oligosaccharide, 1- (3- dimethylamino-propyls)-
3- ethyl-carbodiimide hydrochloride mixing is reacted, and what is obtained is to contain N-(N '-oleoyl glycyl)The reaction of-chitosan oligosaccharide is molten
Liquid.Due to the system that this reaction system is aqueous phase, using water miscible 1- (3- dimethylamino-propyls) -3- ethyl carbodiimide salt
Hydrochlorate is condensing agent, and reaction can be made to be completed in one pot, eliminates the trouble of intermediate separation.
The present invention is also by step 3)The reaction solution that reaction is obtained carries out centrifugal treating, and the precipitation that centrifuging and taking is obtained is used into second
30 DEG C of vacuum drying after alcohol mixing extracting, obtain N-(N '-oleoyl glycyl)- chitosan oligosaccharide.Purpose is to remove the boiling carried secretly in product
The higher DMF of point so that product is easy to vacuum drying, while can also remove partial impurities.
The present invention is by through dry N-(N '-oleoyl glycyl)After-chitosan oligosaccharide is swelled with DMF, at room temperature with it is a certain amount of
Chlorosulfuric acid, the side reaction that can so avoid violent reaction condition from bringing.React after certain time, reaction solution is neutralized
To neutral, so the highly acid of sulfonic acid can be avoided to cause the degraded of chitosan oligosaccharide(Or the hydrolysis to amido link)Effect.
In addition, the cutoff of bag filter of the present invention is 2000~3000Mw.Because target product is flat
Average molecular weight is retained more than 2000 in dialysis, and the molecular weight of the accessory substance produced in course of reaction is all 2000
Hereinafter, can all it be removed in dialysis procedure.
