Abstract

PURPOSE:To obtain a quickly soluble Glauber's salt having excellent storage stability and quick solubility and suitable as a builder for detergent, dyeing assistant, etc., by adding a specific amount of a cellulose glycolic acid (Ca salt) to powdery Glauber's salt as a binder and forming the mixture. CONSTITUTION:Powdery Glauber's salt is added with 0.05-5wt.% of cellulose glycolic acid or its calcium salt. The mixture is uniformly mixed and compression molded to a tablet or granulated in the form of granules to obtain the objective quickly soluble Glauber's salt. Different from the conventional product produced by the molding of a mixture of Glauber's salt and a small amount of sodium glycolate, the quickly soluble Glauber's salt produced by the present process does not form a local viscous flock in contact with water to enable quick impregnation of the water into the molded article and exhibit excellent solubility.

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.

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.

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.

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.

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.
