ている。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing quickly soluble Glauber's salt, and the Glauber's salt produced by the method of the present invention can be used as detergent builders, dyeing aids, bath additives, and pond water treatment agents. Suitable for a wide range of applications such as

。Conventional technology Glauber's salt can be synthesized by desulfurization of flue gas, a by-product from a rayon factory, or by using raw materials such as natural Glauber's salt, removing impurities contained in them, and then evaporating, separating, drying, and pulverizing them. It is mass produced. Powdered anhydrous sodium sulfate produced by this method absorbs moisture in the air and solidifies during storage, making it difficult to store for long periods of time, making it particularly difficult to store for long periods of time. When doing so, improvements are also required from the viewpoint of workability, such as the generation of dust.

水塩が用いられているが、芒硝の十水塩は、転移温度（

定性が著しく低下する。In the dyeing field, decahydrate of Glauber's salt is used to increase solubility, but decahydrate of Glauber's salt has a transition temperature (
If the temperature exceeds 32.4°C, it will begin to dissolve itself, and at high temperatures such as in the summer, melting and solidification phenomena will occur, resulting in a significant decrease in storage stability.

芒硝の固結を防止する方法が開示されている。JP-A-58-32015 discloses a method for preventing caking of Glauber's salt by adding a small amount of carboxymethyl cellulose (sodium cellulose glycolate) to powdered Glauber's salt and granulating it into granules. ing.

な溶解性を有しているが、必ずしも満足すべき状態にあ
ると言えなかった。Problems to be Solved by the Invention Granular Glauber's Salt, which is granulated by adding cellulose sodium glycolate to powdered Glauber's Salt, has relatively good solubility without caking, but the condition is not necessarily satisfactory. I couldn't say it was there.
課題を解決するための手段
本発明者等は、このような事情に鑑み、種々の試験研究

粒状に造粒することによって、貯蔵安定性が良好であり
、且つ速溶性に優れた芒硝の製造方法を見い出した。Means for Solving the Problems In view of the above circumstances, the inventors of the present invention have conducted various tests and studies, and have found that cellulose glycolic acid or its calcium salt is added by 0.05 to 5 weight by weight based on powdered Glauber's salt. We have discovered a method for producing Glauber's salt that has good storage stability and excellent quick solubility, by adding in an amount of 1.5%, uniformly mixing the two, and press-molding or granulating it into granules.
本発明の実施に適する繊維素グリコール酸あるいはその
カルシウム塩は、置換度０．４〜０．９．好ましくは０

量％の水を混練した後、加圧成形すべきである。Cellulose glycolic acid or its calcium salt suitable for carrying out the present invention has a degree of substitution of 0.4 to 0.9. Preferably 0
．． 5 to 0.65. When producing a tablet product in the present invention, powdered Glauber's salt should be kneaded with 0.5 to 3.0% by weight of water and then pressed.
また、本発明において混合造粒機を用いて造粒する際に
は、水分を５〜１５重量％とし、必要に応じて繊維素グ
リコール酸ナトリウム等のバインダーを併用すべきであ
る。Moreover, when granulating using a mixing granulator in the present invention, the water content should be 5 to 15% by weight, and a binder such as cellulose sodium glycolate should be used in combination as necessary.
なお、本発明の実施において、芒硝に対する繊維素グリ
コール酸あるいはそのカルシウム塩の添加料が多すぎる
と、芒硝の性状に変化を与えるのみならず、固結防止作
用が低下する。In the practice of the present invention, if too much of the additive of cellulose glycolic acid or its calcium salt is added to Glauber's salt, it not only changes the properties of Glauber's salt but also reduces the anti-caking effect.

内部に速やかに水が浸透し、優れた溶解性を示すものと
考えられる。When molded by adding a small amount of sodium cellulose glycolate to mirabilite, when it comes into contact with water, the sodium cellulose glycolate dissolves and locally forms viscous flocs.
This is thought to reduce the dissolution rate by inhibiting the contact between Glauber's salt and water, but when molded by adding cellulose glycolic acid or its calcium salt to Glauber's salt,
It is thought that when brought into contact with water, water quickly penetrates into the molded product due to its low viscosity, resulting in excellent solubility.
