(Industrial Application Field) The present invention relates to an aqueous solution of a divalent iron compound, and more specifically, a new and improved aqueous solution of an oxocarboxylic acid with improved stability. Concerning aqueous solutions of iron compounds. (Prior art) Divalent iron compounds such as ferrous sulfate and ferrous chloride are used in deodorizers, iron black, mordants, human waste treatment agents, pharmaceuticals,
It is used as a raw material for various purposes such as tanning and red iron. However, these aqueous solutions are easily oxidized by oxygen in the air or dissolved oxygen.
Therefore, the problem is that it forms a yellow precipitate and is consumed within a short period of time. To deal with this problem, methods of adding amine compounds such as alkanolamines or reducing agents such as tin chloride to divalent iron compound aqueous solutions have been proposed, but even when added in relatively large amounts, there is no stabilizing effect. It has the disadvantage of not being sufficient. Furthermore, a method of adding L-ascorbic acid to an aqueous solution of a divalent iron compound (Japanese Patent Application Laid-Open No. 156539/1982) is known, but in this method, L-ascorbic acid is expensive, and L-ascorbic acid is It has the disadvantage of being limited to acids. (Problems to be Solved by the Invention) Therefore, the present inventors have made extensive studies to solve these drawbacks seen in the prior art, and have found that by blending a water-soluble salt of oxocarboxylic acid, 2.
The present inventors have discovered that it is possible to stabilize iron compounds of high valence for a long period of time even in the air, and have completed the present invention. (Means for Solving the Problems) According to the present invention, there is provided a novel iron compound aqueous solution characterized in that a water-soluble salt of oxocarboxylic acid is blended as a stabilizer into an aqueous solution of a divalent iron compound. provided. Specific examples of the divalent iron compound used in the present invention include ferrous sulfate, ferrous chloride, and ferrous nitrate, but ferrous sulfate is the most preferred due to cost and ease of availability. It is used in The concentration of the iron compound aqueous solution can be appropriately selected within a range that allows the iron compound to be dissolved. On the other hand, the stabilizer used in the present invention is a water-soluble salt of oxocarboxylic acid containing one or more aldehyde group or keto group and one or more carboxyl group in the molecule, and specific examples thereof include glyoxylic acid, malon Oxocontainers such as aldehydic acid, succinaldehydic acid, pyruvic acid, 2-ketobutyric acid, 4-acetylbutyric acid, 2-ketoglutaric acid, 4-keto-nvaleric acid, acetoacetic acid, oxomalonic acid, oxaloacetic acid, acetone dicarboxylic acid, etc. Examples include sodium salts, potassium salts, and ammonium salts of carboxylic acids. The amount of the stabilizer of the present invention added can be appropriately selected depending on the required performance of the target product, but it is usually 2% by weight or more, preferably 3 to 10% by weight based on the iron content in the divalent iron compound. is within the range of If the amount used is too small, the stabilizing effect will be insufficient, and if the amount used is too large, the economy will be poor. (Effects of the Invention) Thus, according to the present invention, the stability of an aqueous solution of a divalent iron compound can be greatly improved.
This stabilized iron compound aqueous solution or various carriers impregnated with this aqueous solution can be used as deodorizers,
It can be used in a wide range of applications as a raw material for water treatment agents, mordants, medicines, pigments, antifungal agents, etc. (Examples) Next, the present invention will be explained in more detail based on Examples. Example 1 A predetermined amount of a water-soluble salt of a predetermined oxocarboxylic acid was added and dissolved in an aqueous solution of ferrous sulfate adjusted to a concentration of 50 g/iron. The PH values of these aqueous solutions were measured. Next, 100 ml of each aqueous solution was placed in a 100 ml beaker, a glass plate was placed on the beaker, and the beaker was left to stand, and the color of the aqueous solution and the timing of precipitation formation were observed. The results are shown in Table 1. From the results in Table 1, in the case of no additives (experiment number 1)
Precipitates in a short time and has poor stability, but
It can be seen that when a water-soluble salt of oxocarboxylic acid is blended, the pH of the aqueous solution is higher than the pH of the aqueous solution of a divalent iron compound, and it is stable over a long period of time.
