The present invention relates to a stabilizer for an aqueous solution containing 2-aminocyclohexanone oxime (hereinafter abbreviated as AmOX) or a salt thereof, and particularly to a stabilizer for suppressing the decomposition of AmOX or a salt thereof in an aqueous solution. AmOX is used for a variety of purposes, including as a raw material for the production of L-lysine or D,L-lysine, which is an essential amino acid, as well as for the production of pharmaceuticals, agricultural chemicals, and industrial chemicals, and its use is currently being considered. It is being Solvent or AmOX for purifying AmOX
As a solvent when using as a raw material for reaction,
Water is often used and therefore AmOX is often used as an aqueous solution. However, although AmOX can maintain a certain degree of stability in crystalline form, when it is made into an aqueous solution,
Since decomposition occurs and the product becomes extremely unstable, especially under heating, a decrease in purification yield, reaction yield, etc. is unavoidable. Conventionally, one method for stabilizing such an AmOX aqueous solution is to
It has been known that AmOX can be quickly stabilized as an aqueous hydrochloride solution, but decomposition in an aqueous solution is somewhat alleviated when AmOX hydrochloride is used.
It was still not enough. Moreover, nothing effective as a stabilizer for AmOX aqueous solutions or AmOX salt aqueous solutions has been found. An object of the present invention is to provide an excellent stabilizer for an aqueous solution of AmOX or an aqueous solution of an AmOX salt. The present inventors have discovered that even AmOX, which is relatively stable, gradually decomposes in an aqueous solution even at room temperature.
It has been found that decomposition products such as 3,4,6,7,8,9-octahydrophenazine, perhydro-N 5 -hydroxy-4a,5a-aminooxyphenazine, and nioxime are produced. Therefore, the present inventors conducted a detailed study on the relationship between AmOX and the production of these decomposition products, and as a result, found that compounds containing aluminum are extremely effective in suppressing the decomposition of AmOX, leading to the present invention. That is, the present invention is a stabilizer for an aqueous solution containing 2-aminocyclohexanone oxime (AmOX) or a salt thereof, which is mainly composed of an aluminum compound. The stabilizer of the present invention has an aluminum compound as its main component, and can contain any other compound as long as it does not promote the decomposition of AmOX or its salt. As the aluminum compound of the present invention, any compound such as an inorganic aluminum compound or an organic aluminum compound can be used. In consideration of stabilizing effect, economy, handling, etc., preferably the inorganic aluminum compound is aluminum chloride, aluminum sulfate, aluminum nitrate, potassium alum, etc., and the organic aluminum compound is preferably aluminum carboxylate such as aluminum acetate. Further, the aluminum compound of the present invention can be used regardless of whether it is water-soluble or poorly soluble. The amount of the stabilizer of the present invention added is 5 to 5,000 ppm, preferably 5 to 1,000 ppm of aluminum based on AmOX. If the amount added is less than 5 ppm, the effect of the present invention will not be fully exhibited, and
Although there is no problem if the amount exceeds 5000 ppm, it is economically disadvantageous. AmOX used in the present invention can be produced by any method. for example,
A method of reacting hydroxylamine with 2-chlorocyclohexanone in liquid ammonia (Tokuko Sho)
44-2704) or bis(2-chlor-1
- A method for aminating nitrosocyclohexane) in the presence of a large excess of ammonia (Unexamined Japanese Patent Publication No. 1973-
36436) can also be used. As the AmOX salt used in the present invention, any AmOX salt can be used, but preferably mineral acid salts such as AmOX hydrochloride, sulfate, and nitrate can be used. These salts can be easily obtained by bringing AmOX into contact with an acid solution such as a mineral acid. The stabilizer of the present invention can be used in aqueous solutions of AmOX or its salts at any concentration. The concentration is
AmOX can be used from extremely dilute aqueous solutions to saturated aqueous solutions. As detailed above, since the stabilizer of the present invention has an aluminum compound as its main component, it can significantly suppress the decomposition of AmOX or its salt in an aqueous solution, and can effectively stabilize an aqueous solution of AmOX or its salt. It becomes possible to stabilize it. The stabilizing effect of the present invention is even more exerted in a basic region where AmOX is unstable or in the presence of iron, which has the effect of accelerating the decomposition of AmOX. In addition, the stabilizer of the present invention has the effect of coagulating and precipitating impurities and removing them from the system, so when used industrially, the turbidity of the AmOX aqueous solution decreases,
At the same time, it also has a purifying effect, such as improving the transparency of visible light. Hereinafter, the present invention will be specifically explained with reference to Examples. Examples 1 to 3 AmOX hydrochloride (AmOX HCl) 10.00 g of ferrous chloride tetrahydrate (FeCl 2 4H 2 O) was added to AmOX at 100 ppm as Fe, and aluminum chloride was added as a stabilizer.・Hexahydrate salt (AlCl 3・6H 2 O)
was added as Al to AmOX at 400 ppm, and the pH was adjusted to 7.5, 8.5, and 9.5 with aqueous ammonia, and the total amount was 80 g to obtain an AmOX aqueous solution. In addition, as a comparative example, the stabilizer AlCl 3 .
An AmOX aqueous solution without addition of 6H 2 O was similarly prepared. Take 10.00g of each AmOX aqueous solution into an 18φ test tube,
After putting in a rotor, the tube was sealed with N2 and heated and stirred in a 90°C oil bath. 1 hour later, 2 hours later,
Table 1 shows the results of determining the decomposition rate of AmOX from the residual amount of each AmOX after 3 hours.

The OHP production rate was found to be 4.2%.

[Table] Example 10 Bis(2-chloro-1-nitrosocyclohexane) was aminated using excess ammonia in an amination reactor made of SUS304. An equimolar mixture of AmOX and ammonium chloride obtained by removing excess ammonia from the amination reaction product was made into a 15% aqueous solution, 10.00 g of it was placed in an 18φ test tube, and aluminum chloride 6 was added as a stabilizer.
1.00 g of a 0.4% aqueous solution of aqueous salt (400 ppm as Al based on AmOX) was added, and after sealing with N2 , the tube was sealed and left at room temperature. As Comparative Example 6, a solution containing no aluminum chloride was also left under the same conditions. After 20 days, the test tube was opened and the decomposition rate of AmOX was determined to be 14.7%. When the visible light (500 nm) transmittance of the aqueous solution diluted five times with water was measured, it was 63.8%. On the other hand, when no aluminum was added, the decomposition rate of AmOX was 65.3%, and the 500 nm transmittance was 45.4%.
