聚酮树脂生产的技术难点

Research and selection of catalysts: Catalysts are key to the production of polyketide resins, and their activity, selectivity, and stability directly affect product quality and production efficiency. At present, although palladium based catalysts are widely used, there are still some problems, such as high catalyst costs, which limit the economic benefits of large-scale production; And the activity and selectivity of the catalyst need to be further improved to precisely control the molecular structure and properties of the polymer and produce products that meet different application requirements. Developing new, efficient, low-cost, and environmentally friendly catalysts is currently an important challenge.

Accurate control of reaction conditions: The copolymerization reaction is highly sensitive to reaction conditions such as temperature, pressure, and raw material ratio. Even minor changes in conditions can lead to significant alterations in the molecular structure and properties of polymers. For example, excessive temperature may cause the molecular weight distribution of polymers to widen, affecting the consistency of product performance; Improper pressure control may result in incomplete reactions or excessive production of by-products. Therefore, precise temperature and pressure control systems, as well as strict monitoring and adjustment of raw material ratios, are required to ensure the reaction proceeds, which places high demands on production equipment and control technology.

Product separation and purification: The separation and purification process of polyketide resin is relatively complex because there are multiple components in the reaction system, and the separation difficulty between polyketide resin, catalyst, and by-products is high. Traditional separation methods may result in product loss or residual impurities, affecting product quality. Developing efficient and economical separation technologies that can improve product purity and reduce product losses is one of the technical challenges that need to be addressed in the production of polyketide resins.

Environmental Protection and Sustainability: Some raw materials and solvents used in the production process of polyketide resin may be harmful to the environment, and certain waste may be generated during the production process. How to reduce the impact on the environment and achieve green production is a challenge faced by the polyketide resin industry. For example, finding more environmentally friendly solvents to replace traditional organic solvents, as well as effectively treating waste and recycling resources, are all issues that need to be addressed to meet increasingly strict environmental requirements and sustainable development needs.
