Proposals for the Development of Fine Chemical Industry


Scientific and technological innovation is not only the fundamental driving force for the development of fine chemical industry, but also the key means to improve product quality and added value. It is suggested that the fine chemical industry should increase investment in scientific and technological innovation, strengthen basic research and applied research, break through key core technologies, and develop high-end, differentiated and customized products to meet market demand and consumer demand.

Development Trend of Fine Chemical Industry in 2023


With the development of the national economy and the diversification of social needs, the market has higher, newer and more detailed requirements for the quality, variety and function of fine chemical products. Traditional bulk general-purpose products have been unable to meet the needs of the market, while high-end, differentiated and customized products have become the new darling of the market. These products have higher technical content, stronger market pertinence, higher added value and greater development potential.

Fine Chemical Industry Market Status and Challenges in 2023


Fine chemical industry refers to the production of fine chemicals industry, known as fine chemical industry. Products in this industry refer to chemical products with specific application functions, technology-intensive, commercial and high added value. There are many types of fine chemical products and a wide range of downstream applications.

Physochemical Properties and Technology of Sodium m-Aminobenzene Sulfonate


Off-white to light red crystalline or slurry. Sodium m-aminobenzene sulfonate was obtained from nitrobenzene by sulfonation reaction and then reduced. Used in the manufacture of azo dyes and pharmaceutical intermediates, active, acidic, vulcanized and other dyes.

M-Aminophenol Industry Market Report to 2023


M-Aminophenol is an important chemical product, widely used in dyes, cosmetics, plastics, rubber and other industries. The purpose of this report is to study and analyze the market of m-aminophenol industry in order to understand its development potential and market prospects.

The focus of fine chemical development shifts to China and India


With the recovery of the global economy, the world's total annual output value of chemical products reached 3.4 trillion US dollars, an increase of 8.8 percent compared with 2009. The market size of fine chemicals is nearly 1.5 trillion US dollars, and the refinement rate has dropped to 44.1 percent. The main reason is that in recent years, the global market, especially the Middle East, has invested heavily and concentrated in the fields of large oil refining, large petrochemicals, and large chemicals.
