Concrete water-reducing agents promote the development of 3-mercaptopropionic acid industry

   3-mercaptopropionic acid, also known as β-mercaptopropionic acid, thiopropionic acid, thiohydropropionic acid, the appearance of colorless or light yellow transparent liquid or crystal, can be miscible with water, alcohol and ether. 3-merphyto-propionic acid is an important industrial raw material with many uses. It can be used as an intermediate of medicine fenalol, as polyvinyl chloride stabilizer, antioxidant, catalyst and biochemical reagent, etc.

    In the early stage, due to the overall amount of 3-merphyto-propionic acid in fenalol intermediates, polyvinyl chloride stabilizers and other fields is less, and the production process is complex, there are almost no large-scale production enterprises in China. In recent years, with the continuous development of chemical technology, the downstream application range of 3-mercaptopropionic acid has gradually expanded, especially in the field of concrete admixtures. 3-mercaptopropionic acid (3-mercaptopropionic acid) has been widely developed and applied in the production of new cement admixtures, polycarboxylic acid water reducing agent, as a high performance mediator to control molecular weight and improve the water reducing rate and slump retention performance of concrete. At present, polycarboxylic acid high performance water reducing agent with 3-mercaptopropionic acid as raw material is a kind of concrete water reducing agent with the best comprehensive performance at present, and it forms a larger substitute for other water reducing agents, and its market scale is expanding year by year.

    At present, the largest application field of 3-mercaptopropionic acid in China is concrete water reducing agent. Due to the relatively low requirements for 3-mercaptopropionic acid products in the field of concrete water reducing agent, the market demand for 3-mercaptopropionic acid continues to grow as the application technology of 3-mercaptopropionic acid in the field of concrete water reducing agent continues to mature. According to the "2020-2024 3-mercaptopropionic acid industry in-depth Market Research and investment strategy Recommendation Report" released by New Thought, the demand for 3-mercaptopropionic acid in China in 2019 was 4100 tons, an increase of 8.5%. Among them, the demand for concrete water-reducing agents is 2,700 tons.

    At this stage, the main producers of 3-mercaptopropionic acid in the world include developed countries such as Germany and Japan, as well as developing countries such as China and India, among which the 3-mercaptopropionic acid produced by developed countries is of higher quality. China's 3-mercaptopropionic acid industry started late, in recent years, with the extensive application of 3-mercaptopropionic acid in the field of concrete water reducing agents, its market scale has gradually increased, attracting more enterprises to enter.

    Industry analysts said that in the future, with the increasing use of concrete in China, as well as the continuous development of China's pharmaceutical industry and PVC industry, China's demand for 3-mercaptopropionic acid products will continue to grow, and the overall prospects of the industry are good. Although the number of enterprises with production capacity in China's 3-mercaptopropionic acid industry continues to increase, and the production scale continues to expand, but limited by the technical level, domestic 3-mercaptopropionic acid products are mostly medium and low-end products. Mercaptopropionic acid enterprises should increase investment in product and process research and development, constantly improve and enhance the synthesis process and product quality, optimize the product portfolio, and win the market with high-quality products.
