Potassium Ferrocyanide Trihyrate, with the CAS number 14459-95-1, is a crystalline compound. It has a chemical formula of K4[Fe(CN)6]·3H2O. The molar mass of this trihydrate form is approximately 422.39 g/mol. It is a yellow, odorless solid that is highly soluble in water. The compound is stable under normal conditions but should be stored in a cool, dry place away from strong acids and oxidizing agents. It has a density of about 1.85 g/cm³.
Potassium Ferrocyanide Trihyrate has a wide range of applications in different industries. In the food industry, it is used as an anti - caking agent in table salt. It prevents the salt from clumping together by absorbing moisture and keeping the salt free - flowing. This helps in maintaining the quality and usability of the salt over time.
In the metallurgy industry, it is used in the process of metal surface treatment. It can form a protective layer on the metal surface, which improves the corrosion resistance of the metal. This is especially useful for iron and steel products, as it helps to extend their service life.
In the laboratory, it is a common reagent. It can be used in chemical analysis, such as in the detection of certain metal ions. For example, it can react with copper ions to form a characteristic precipitate, which helps in the qualitative analysis of copper in a solution.
When using Potassium Ferrocyanide Trihyrate in the food industry as an anti - caking agent, it should be added in the appropriate proportion. Usually, the recommended dosage is specified by relevant food safety standards. It is important to ensure thorough mixing with the salt to achieve a uniform anti - caking effect.
In metal surface treatment, the product is typically dissolved in water to form a solution. The metal parts are then immersed in this solution for a certain period of time, depending on the type of metal and the desired treatment effect. After immersion, the parts should be rinsed thoroughly to remove any residual solution.
In the laboratory, when using it as a reagent, the appropriate amount should be weighed accurately according to the experimental requirements. It is usually dissolved in a suitable solvent, such as water, before use. Care should be taken during handling to avoid contact with skin and eyes, and all operations should be carried out in a well - ventilated area.
A salt manufacturing company was facing the problem of salt caking during storage and transportation. They decided to use Potassium Ferrocyanide Trihyrate as an anti - caking agent. By adding the recommended amount of the product to the salt during the production process, they noticed a significant improvement. The salt remained free - flowing even after long - term storage, which improved customer satisfaction and reduced product losses.
A metallurgical factory wanted to improve the corrosion resistance of its steel products. They used a solution of Potassium Ferrocyanide Trihyrate for surface treatment. After treatment, the steel products were tested in a corrosive environment. The results showed that the treated steel had a much longer service life compared to the untreated ones, which led to cost savings in terms of replacement and maintenance.
In a research laboratory, scientists were trying to detect the presence of copper ions in a complex solution. They used Potassium Ferrocyanide Trihyrate as a reagent. By adding a small amount of the reagent solution to the sample, a characteristic brown - red precipitate was formed, indicating the presence of copper ions. This simple and effective method helped in their research work.
