The properties of oxalic acid
in the description of oxalic acid (Edta Acid)
The properties of oxalic acid
are specific. It is a white crystalline powder, slightly soluble in cold water, and has better solubility in hot water. It is weakly acidic and can neutralize with alkali substances to form corresponding salts. Its molecular structure is unique, containing functional groups such as carboxyl groups. This structure gives it the ability to form stable complexes with many metal ions. This property is of great significance in many fields.

Application of dioxalic acid
1. ** Application in chemical analysis **: In the field of chemical analysis, oxalic acid is widely used. Often used as a complexometric titration reagent, because it can precisely complex with a variety of metal ions, and the complexation ratio is constant. With this, the content of metal ions such as calcium, magnesium, zinc, iron can be accurately measured. For example, in water quality testing, it can measure the concentration of calcium and magnesium ions in water to determine the hardness of water, which is of great significance for the quality control of industrial water and drinking water.
2. ** Application in industrial production **: In the industrial field, oxalic acid is also indispensable. In the electroplating industry, it can be used as a masking agent for metal ions to prevent other metal ions from interfering with the electroplating process, thereby improving the quality and uniformity of the coating. In the paper industry, it can complex with metal ions in pulp, avoid metal ions catalyzing the oxidation and yellowing of paper, and prolong the service life of paper. In the printing and dyeing industry, it can adjust the concentration of metal ions in the dye to ensure uniform dyeing and bright color.
3. ** Applications in the field of medicine **: In medicine, oxalic acid also contributes. It can be used to prepare certain drugs, and it can use its complexation with metal ions to assist drugs in achieving specific curative effects. In addition, in medical testing, it can be used to remove metal ions from blood samples to ensure the accuracy of test results.

Production of glycolic acid
Production of glycolic acid, there are various ways. The common ones are obtained by chemical synthesis using the corresponding organic compounds as raw materials. First, it can be prepared by a series of chemical reactions such as oxidation and condensation of specific carboxyl compounds. The production process requires strict control of the reaction conditions, such as temperature, pressure, and the proportion of reactants. Appropriate reaction temperature and pressure can make the reaction proceed efficiently and improve the yield. Precise control of the proportion of reactants can reduce the occurrence of side reactions and ensure product purity. Production equipment also needs to be carefully selected and maintained to ensure the stability and safety of the production process.
