。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a divalent iron compound aqueous solution, and more specifically,
The present invention relates to a novel aqueous solution of an iron compound with improved stability, which is obtained by blending erythorbic acid into an aqueous solution of a divalent iron compound.

形成して消費されてしまうことが問題となりている。(Prior art) Divalent iron compounds such as ferrous sulfate and ferrous chloride are used as raw materials for many uses such as deodorizers, iron black, mordants, floor treatment agents, medicines, bookbinding, pengara, etc. It's being used. but,
These aqueous solutions are easily oxidized by oxygen in the air or dissolved oxygen, which poses a problem in that they form yellow precipitates and are consumed within a short period of time.
この問題に対処する為、アルカノールアミン等のアミン
化合物や塩化スズなどの還元剤を２価の鉄化合物水溶液
に添加する方法が挙げられているが、比較的多量に添加
しても安定効果は充分とはいいがたく、又毒性の面から
用途によっては制限を受けるという欠点を有する。To deal with this problem, methods have been proposed in which amine compounds such as alkanolamines or reducing agents such as tin chloride are added to divalent iron compound aqueous solutions, but even when added in relatively large amounts, the stabilizing effect is sufficient. However, it also has the drawback of being limited depending on its use due to toxicity.

を見出し、本発明を完成するに至った。(Problems to be Solved by the Invention) Therefore, the inventors of the present invention have conducted extensive studies to solve these drawbacks seen in the prior art, and as a result, they have added nilinelupic acid to an aqueous solution of a divalent iron compound. In particular, the inventors have discovered that it is possible to stabilize divalent iron compounds for a long period of time even in the air, and have completed the present invention.
（問題点を解決するための手段）

る。(Means for Solving the Problems) According to the present invention, there is provided a novel iron compound aqueous solution characterized in that erythorbic acid or a water-soluble salt thereof is blended as a stabilizer into an aqueous solution of a divalent iron compound. I can provide it.
本発明で用いられる２価の鉄化合物の具体例としては、
硫酸第一鉄、塩化第一鉄、硝酸第−鉄等が挙げられるが
、コストや入手の容易性から硫酸第一鉄が最も好んで使
用される。かかる鉄化合物水溶液の濃度は溶解可能な範
凹内で適宜選択することができる。Specific examples of divalent iron compounds used in the present invention include:
Examples include ferrous sulfate, ferrous chloride, and ferrous nitrate, but ferrous sulfate is most preferably used because of cost and availability. The concentration of the iron compound aqueous solution can be appropriately selected within the soluble range.
一方、安定化剤として用いられるエリソルビン酸は食品
などの酸化防止剤として公知のものでおるが、非常に酸
化され易い２価の鉄化合物の安定化剤として顕著な効果
を示すことは全く知られていなかった。エリソルビン酸
は酸の形で使用してもよいが、ナトリウム塩、カリウム
塩などのごとき水溶性の塩の形で用いることもできる。On the other hand, erythorbic acid, which is used as a stabilizer, is known as an antioxidant for foods, etc., but it is completely unknown that it exhibits a remarkable effect as a stabilizer for divalent iron compounds, which are highly oxidized. It wasn't. Erythorbic acid may be used in the acid form, but it can also be used in the form of water-soluble salts such as sodium salt, potassium salt, etc.
エリソルビン酸またはその塩の添加量は目的物の要求性
能に応じて適宜選択しうるが、通常は２価の鉄化合物中
の鉄分に対し２重量−以上であシ、好ましくは３〜１０
重量％の範囲である。使用量が過度に少ない場合には安
定化効果が不充分であシ、逆に過度に多い場合には経済
性に劣るようになる。The amount of erythorbic acid or its salt to be added can be appropriately selected depending on the required performance of the target product, but it is usually 2 weight or more, preferably 3 to 10 weight, based on the iron content in the divalent iron compound.
% by weight. If the amount used is too small, the stabilizing effect will be insufficient, and on the other hand, if the amount used is too large, the economy will be poor.

察した。結果を第１表に示す。Example 1 A predetermined amount of erythorbic acid was added and dissolved in an aqueous solution of ferrous sulfate adjusted to a concentration of 50 g/3 as iron content. 100 g of each aqueous solution was put into a 100 g 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 the formation of precipitate were observed. The results are shown in Table 1.

られた。From the results in Table 1, it can be seen that when no additive was added (experiment number 1), precipitation occurred in a short period of time and the stability was poor, but when nilinelupic acid was added, the stability remained for a long period of time: J'-W/ J:,
Example 2 An experiment was conducted in the same manner as Experiment No. 4 in Example 1 except that sodium erythorbate was used in place of erythorbic acid. Almost the same results were obtained.
