1、Overview of Oxalic Acid industry
Oxalic acid is a binary acid. It is connected by two carboxyls, and the acidity is stronger than other binary acids and has strong reducibility. Oxalic acid is colorless and transparent crystal, and its solid form is easy to transport and store compared with most strong acids. The main products of oxalic acid industry include industrial oxalic acid, refined oxalic acid and oxalic acid derivatives
The production of oxalic acid by "carbohydrates oxidation process" and "sodium formate process" is mainly used by the oxalic acid production enterprises in China. The output of oxalic acid produced by these two processes accounts for about 80% of the total output of oxalic acid in China. The raw materials required for "carbohydrates oxidation method" are mainly carbohydrates (starch, glucose, etc.) and nitric acid, and the raw materials required by sodium formate method are mainly coal, caustic soda and sulfuric acid. Therefore, the development of the upstream industries of starch, glucose, nitric acid, sulfuric acid, coal, caustic soda and other oxalic acid will have a great impact on the oxalic acid industry in China.
Oxalic acid is mainly used in pharmaceutical, rare earth, fine chemical industry, printing and dyeing industries. Therefore, the development of these industries will have a profound impact on the future of oxalic acid industry in China. With the rapid development of economy, many traditional industries have gradually subdivided into emerging sub industries. The application of oxalic acid has been expanding and deepening with the emergence of emerging industries, which promotes the specialized production of oxalic acid derivatives (including oxalate etc.).
The development of oxalic acid industry is closely related to the downstream industry, and the sustainable development of downstream industry will directly promote the development of oxalic acid. According to statistics, pharmaceutical, rare earth and fine chemical industry are the main application fields of oxalic acid industry, with the proportion of application being 27%, 26% and 21% respectively.
2、Analysis of import and export status of Oxalic Acid industry in China
Compared with foreign developed countries, the industrial production of Oxalic Acid in China started late, but the development speed is very fast, especially with the development of pharmaceutical, rare earth, fine chemical and other industries, China has become the largest oxalic acid producer in the world.
Similar to the development trend of global processing and manufacturing industry, oxalic acid is rarely produced in developed countries. The whole oxalic acid manufacturing industry is transferred to developing countries and regions, and most developed countries rely on imports. Among the developing countries and regions, oxalic acid production lines have been built in China, South Korea, Taiwan, India and Brazil. However, due to resources, geographical location and other reasons, the production scale of oxalic acid is small in other countries and regions except China. In recent years, the export volume of oxalic acid in China has been increasing. By 2020, the export volume of oxalic acid in China will be 117045 tons, a year-on-year increase of 24.8%; the import volume will be 91 tons, a year-on-year decrease of 33.6%.
Import and export statistics of Oxalic Acid in China from 2015 to 2020
In terms of import and export amount, according to statistics, as of 2020, the import amount of oxalic acid in China was US $1.05 million, a year-on-year increase of 7.1%; the export amount was US $71.45 million, a year-on-year increase of 10.9%.

3. Analysis of the development trend of Oxalic Acid industry in China
(1) Develop large-scale enterprises and eliminate backward production capacity
At present, although there are several large-scale production enterprises in the Oxalic Acid industry in China, there are still many enterprises with small scale, scattered layout and backward technology. Oxalic acid enterprises in China are mainly distributed in Shandong, Fujian, northeast, Inner Mongolia, Shanxi and other places. Some enterprises are far away from the consumption market and raw material market, which leads to high cost and lack of competitiveness. In addition, most enterprises in oxalic acid industry still adopt carbohydrates oxidation process and sodium formate process. Some enterprises have high production cost, high energy consumption and environmental protection problems. In the future, the oxalic acid industry will adjust its industrial structure, develop large-scale enterprises and eliminate backward production capacity.
(2) Improve product structure and increase the output of high added value products
At present, the products of oxalic acid industry in China are mainly industrial oxalic acid, the scale of refined oxalic acid and oxalate production is small, and the product structure is unreasonable. The oxalic acid industry in China will continue to develop to high value-added products, and refining oxalic acid and oxalic acid derivatives will become the future product development direction.
