Oxalic Acid

1. Bleaching and reduction.
Oxalic acid has strong bleaching properties. It can effectively remove pigments and impurities on cellulose, making the fiber whiter. In the textile industry, oxalic acid is often used as a bleaching agent for the bleaching treatment of natural fibers such as cotton, linen, and silk to improve the whiteness and gloss of the fibers. In addition, oxalic acid also has reducing properties and can react with certain oxidants, so it also plays a role as a reducing agent in some chemical reactions.

2. Metal surface cleaning.
Oxalic acid has significant application effects in the field of metal surface cleaning. It can react with oxides, dirt, etc. on the metal surface and dissolve or transform them into substances that are easy to remove, thereby achieving the purpose of cleaning the metal surface. In the production process of metal products, oxalic acid is often used to remove oxides, oil stains and rust products from the metal surface to restore the original luster and performance of the metal surface.

3. Industrial dye stabilizer.
Oxalic acid can also be used as a stabilizer for industrial dyes to prevent precipitation and stratification of dyes during storage and use. By interacting with certain functional groups in the dye molecules, oxalic acid can improve the stability of the dye and extend its service life. This stabilizer role of oxalic acid is of great significance in the dye manufacturing and textile printing and dyeing industries.

4. Tanning agent for leather processing.
During leather processing, oxalic acid can be used as a tanning agent to help the leather better fix its shape and maintain softness. Through the tanning process, oxalic acid can chemically react with the collagen fibers in the leather to increase the strength and durability of the leather. At the same time, oxalic acid tanning agents can also improve the color and feel of leather, making it more beautiful and comfortable.

5. Preparation of chemical reagents.
As an important organic acid, oxalic acid is also a raw material for the preparation of many chemical reagents. For example, oxalic acid can react with alkali to form oxalates. These salts have wide applications in chemical analysis, synthetic reactions and other fields. In addition, oxalic acid can also be used to prepare other organic acids, esters and other compounds, providing a rich source of raw materials for the chemical industry.

6. Photovoltaic industry application.
In recent years, with the rapid development of the photovoltaic industry, oxalic acid has also played an important role in the manufacturing process of solar panels. In the production process of solar panels, oxalic acid can be used as a cleaning agent and corrosion inhibitor to remove impurities and oxides on the surface of silicon wafers, improving the surface quality and photoelectric conversion efficiency of silicon wafers.
