Our product is High Quality Oxalic Acid Dihydrate with the CAS number 6153 - 56 - 6. Oxalic acid dihydrate has a molecular formula of C₂H₂O₄·2H₂O and a molecular weight of approximately 126.07 g/mol. It appears as colorless, transparent crystals or a white crystalline powder. This product is highly soluble in water, ethanol, and ether. It has a melting point in the range of 101 - 102 °C (decomposes). The purity of our high - quality oxalic acid dihydrate can reach up to 99% or even higher, which meets the strict requirements of various industrial applications.
Oxalic acid dihydrate has a wide range of applications across different industries. In the metal industry, it is commonly used for metal surface treatment. It can remove rust, scale, and other impurities from metal surfaces, making the metal ready for further processing such as plating or painting. In the textile industry, it serves as a reducing agent and a bleaching agent. It can help to remove stains and brighten the color of textiles. In the pharmaceutical industry, it is used as an intermediate in the synthesis of certain drugs. Additionally, it can be used in the production of ink, dyes, and as a mordant in the printing and dyeing process.
When using oxalic acid dihydrate, it is crucial to follow safety precautions. First, always wear appropriate personal protective equipment, including gloves, goggles, and a lab coat. When diluting the product in water, always add the acid to water slowly and stir continuously to avoid splashing. The concentration of the solution should be adjusted according to the specific application. For example, for rust removal, a relatively concentrated solution (around 10 - 20%) can be used, while for textile bleaching, a more diluted solution (around 1 - 5%) is usually sufficient. After use, the remaining solution should be properly disposed of in accordance with local environmental regulations.
Case 1: Rust Removal on Iron Tools
A small workshop had a collection of iron tools that were severely rusted. They prepared a 15% oxalic acid dihydrate solution by dissolving the appropriate amount of the product in water. They soaked the rusted tools in the solution for about 2 - 3 hours. After soaking, they noticed that the rust had significantly reduced. They then rinsed the tools thoroughly with water and dried them. The tools were restored to a usable state, and the surface was clean and ready for further treatment or use.
Case 2: Textile Bleaching
A textile factory wanted to brighten a batch of cotton fabrics. They prepared a 3% oxalic acid dihydrate solution. They immersed the fabrics in the solution at a temperature of about 50 - 60 °C for 30 - 40 minutes. During this process, the solution gradually removed the natural color impurities and stains on the fabrics. After bleaching, the fabrics were washed several times with water to remove any remaining acid and then dried. The result was bright and clean - looking cotton fabrics.
