Because the itaconic acid production technology is monopolized by a few countries, there is a large gap in the international market. According to the import and export companies in Hunan, Sichuan, Jiangsu, and Shaanxi provinces, Japan, Australia, New Zealand, the United States, and Spain are all in urgent need of itaconic acid, with an international market gap of approximately 70,000 tons. China National Chemical Information Center and other units are involved in itaconic acid. The market statistics and forecast that China's total demand in the last two years will reach about 22,000 tons, China's current itaconic acid production scale is about 14,000 tons, so the product is very optimistic about the international and domestic markets. At present, the domestic market uses 2,000 tons of styrene-butadiene latex, about 1,500 tons for the chemical fiber industry, and 1,000 tons for the ion exchange resin industry. In addition, itaconic acid is used in water treatment technology, high-strength glass fiber reinforced plastics and pesticide intermediates, and detergents. The field also has a wide range of uses. Only Lanzhou Chemical Fiber Plant imports about 500 tons of itaconic acid each year. Shanghai BASF needs about 800 tons of itaconic acid each year. The demand for itaconic acid in the international market is still growing at a rate of 12% per year. According to the introduction of relevant foreign trade departments, at the end of 1999, a number of U.S. companies had come to the Mainland to negotiate the import of itaconic acid products. The annual demand of each company was over 10,000 tons. Only Fusang of Japan sold from domestic acquisitions to Japan last year. The itaconic acid amounted to 3,000 tons. In the province, two manufacturers of itaconic acid, which uses cornstarch as raw material, were in short supply in 1999. The products were sold to Japan, the United States, South Korea, India and Taiwan and other countries and regions. Among them, the Qingdao Yingtai Wine Group's annual output of 1,000 tons of itaconic acid project was formally put into operation in August 1999, and 1,800 tons of sales contracts were signed at the end of that year. With the successful development of itaconic acid products and the unique properties of itaconic acid, which are increasingly recognized by people, its application range is rapidly expanding. Therefore, the potential market for itaconic acid can not be ignored and has broad prospects for development. Due to the long-term dependence on imports, many of the chemical products related to it have been affected. In addition, Zhejiang Guoguang Biochemical Co., Ltd. has an annual output of 10,000 tons. For example, the best cross-linking agent for acrylic acid is itaconic acid. Since there is no such product in China, most Manufacturers have to replace itaconic acid with divinylbenzene, resulting in the quality of ion exchange resin can not be improved. Another example is the use of itaconic acid as the third monomer in the synthesis of acrylic. It plays an important role in the quality, gloss, and dyeing of acrylic products. In the world, itaconic acid acrylic is known as “Standard Acrylic”. In the foreign oil recovery industry, itaconic acid, as a high-melting point intermediate, has been widely used in the decomposing fluids of deep well production. China has made breakthrough progress in this area, with proven reserves in the offshore China. A large number of large-scale deep-well oil fields will be gradually developed, and itaconic acid will have a wider application prospect in this field. According to an authoritative source, with the expansion and construction of many chemical fiber factories in the world, the production of acrylic fibers will increase significantly. In addition, itaconic acid also has a wide range of uses in water treatment technology, high-strength glass fiber reinforced plastics and pesticide intermediates, detergents, and medicines. With the successful development of itaconic acid products and the unique properties of itaconic acid, which are increasingly recognized by people, its application range is rapidly expanding. Therefore, the potential market for itaconic acid can not be ignored and has broad prospects for development.
