Abstract

PURPOSE:To prepare the title chitin which has a sufficient strength for use as a column packing and is uniform in particle diameters, by N-acetylating granular, porous chitosan to give granular, porous chitin and reacting the product with a cyanogen halide in an alkaline atmosphere. CONSTITUTION:Flaky, high-MW chitosan is heated in an aq. soln. of sodium perborate to give low-MW chitosan. The product is dissolved in an aq. soln. of acetic acid, and the soln. is processed into granular, porous chitosan by, e.g., causing it to fall down through a nozzle into a basic coagulant under pressure. The granular, porous chitosan is then N-acetylated by, e.g., reacting it with acetic anhydride in ethanol to give granular, porous chitin, which is further reacted with a cyanogen halide (e.g. cyanogen bromide) in an alkaline atmosphere to give cyanogen halide-activated granular, porous chitin which is suitable as a carrier for immobilizing enzymes.

Conventionally, as disclosed in Japanese Patent Publication No. 57-21529, agarose activated with cyanogen bromide has been known, and when activated with cyanogen halide, it reacts with the hydroxyl group in the molecule and reacts with the amino group. It becomes easier. However, when a gel of a polysaccharide such as agarose or dextran as disclosed in the above publication is activated with cyanogen halide and subjected to affinity chromatography or a carrier for immobilized enzyme, the polysaccharide becomes a gel. However, due to the lack of strength, the pressure rises significantly during liquid passage, making it impractical. [Problems to be Solved by the Invention] As mentioned above, the present invention is a novel cyanogen halide that can easily immobilize proteins, peptide amino acids, etc. that have a strength that does not cause pressure loss when used industrially. The above problems were solved by using granular porous chitin developed by the present inventors for the purpose of obtaining an activated polysaccharide.

The present invention provides activated cyanogen halide, which is obtained by N-acetylating granular porous chitosan with an acetylating agent such as acetic anhydride to obtain granular porous regenerated chitin, and then reacting it with cyanogen halide under alkaline conditions. It concerns granular porous chitin. Granular porous chitosan is obtained by dropping an acidic solution of low molecular weight chitosan into a basic solution. The low molecular weight chitosan used in the present invention has an average molecular weight of 10.000 to 230,
000. Low molecular weight chitosan is obtained by heat-treating flaky high molecular weight chitosan in an aqueous sodium perborate solution to obtain high quality chitosan having a desired low molecular weight. Low molecular weight chitosan is acetic acid, dichloric acid II, ! il
Chitosan is dissolved in an aqueous solution of l acid alone or as a mixture to obtain an acidic solution of chitosan. The concentration can be appropriately selected within a range that is easy to handle, but a range of 2 to 20% is preferred. Granular porous chitosan is obtained by dropping a certain amount of the chitosan acidic solution into the basic coagulation liquid under pressure from a nozzle with a pore diameter of 0.1 to 0.25 rMφ. As the basic substance in the coagulation bath, alkaline substances such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, ammonia, and ethylenediamine are used.
As the basic substance, the basic substance is added to water, a polar alcohol such as methanol or ethanol, or a mixture of water and alcohol. The 1q granular porous chitosan obtained is thoroughly washed with a polar solvent until it becomes neutral. After replacing the water with alcohol, the granular porous chitosan thus obtained is reacted with acetic anhydride in ethanol to perform door acetylation, and further treated with an alkaline solution such as aqueous caustic soda to cleave the ester bond. to ensure complete chitinization and produce granular porous regenerated chitin. The granular porous regenerated chitin is reacted with cyanogen halide while adjusting the pH to 10 to 20 with an alkaline solution such as an aqueous solution of caustic soda. As the cyanogen halide, cyanogen bromide and cyanogen chloride are used. The cyanogen halide-activated granular porous chitin thus obtained is composed of chitin, so it has an excellent crystal structure, is a strong granular material, and is homogeneous as can be seen by observing the surface and cut surface of the granular material. It is a porous granule having micropores formed in it. Therefore, since the surface area is large, the amount of cyanogen halide bound increases, the activation ability increases, and the ability to immobilize proteins, peptides, amino acids, etc. having amino groups is also extremely high. The present invention will be described below with reference to Examples, but the present invention is not limited to this scope. In the examples, the specific surface area was determined by rapidly freezing the sample in liquid nitrogen, vacuum drying at 10-4 Torr, -40°C for 8 hours,
After degassing at 140°C for 40 minutes, the specific surface area automatic measuring device (

It was measured by the method. Example 1 Chitosan 609 with a degree of deacetylation of 82% and an average molecular fi of 48.000 was dissolved in 940 g of water containing 113 JJ of vinegar to obtain an acidic chitosan solution with a solid content concentration of 6% by weight. The acidic chitosan solution was placed in a basic solution consisting of 7% caustic soda, 30% methanol, and 63% water with a pore size of 0.15φ.
The spray was dropped from a nozzle and washed with water until it became neutral.The average particle size was 0.1ffifiφ2 and the specific surface area was 64.0T.
Granular porous chitosan with It, /'7 at 1°C was obtained. This 50d was collected and replaced with ethanol four times to completely replace water with alcohol. To this was added 3 times the mole of acetic anhydride, stirred in ethanol for 24 hours, washed until it was acetylated and neutralized, and further added IN-Na011
50 precepts were added, treated for 1 hour, and thoroughly washed with water until it became neutral. Average particle size o, 1mmφ, specific surface area 64.0TIt/g
50 m2 of granular porous chitin was obtained. Further, 50 d of the granular porous chitin was suspended in 250 d of water, and the pH was adjusted to 10 to 12 with 5N caustic soda. 25
While stirring a cyanogen bromide aqueous solution of g/250 g/250 g, little by little,
1) Add 5N caustic soda and react while controlling H to 10-12. After the addition of the 250d cyanogen bromide aqueous solution was completed, the mixture was further stirred for 30 minutes and thoroughly washed with cold water to obtain cyanogen bromide activated granular porous chitin 44. Cyanogen bromide activated granular porous chitin with an average particle size of 0.1 mmφ obtained as above and particle size of 0.11R#I

The results of the investigation were as shown in the drawings.The cyanogen bromide-activated granular porous chitin of the present invention has excellent strength, so the increase in pressure due to liquid passage is small, and it is superior to agarose granules. Furthermore, the obtained cyanogen bromide activated granular porous chitin 1-
After washing with IIH9,0,IN boric acid buffer solution, 1% γ-globulin solution of 2 precepts was added and shaken for 2 hours to immobilize γ-globulin. The amount of immobilization was determined from the difference between the absorbance of the residual solution and the absorbance of the stock solution, and was found to be 5.461yj/M1. In addition, for comparison, γ
- Globulin was immobilized, and the amount of immobilization was determined from the difference between the absorbance of the residual solution and the absorbance of the stock solution, and it was found to be 3.7 q/d. Example 2 When 1% hemoglobin was used instead of 1% γ-globulin on blue-grained porous chitin in Example 1 and the same amount and procedure as in Example 1 was used, the amount of hemoglobin immobilized was 3. It was 051 Ry/d. Example 3 Chitosan 709 having a degree of deacetylation of 78% and an average molecular weight of ff 165,000 was dissolved in 930 g of water containing acetic acid 359 to obtain an acidic chitosan aqueous solution with a solid content concentration of 7%.
