Biocatalysis technology promotes the upgrading of fine chemicals industry

China is the third largest fine chemicals country in the world. The fine chemical industry is closely related to people's lives, especially the organic functional compounds with complex structure and quality requirements, as well as some large varieties of "blockbuster" drugs related to people's health

fine chemicals include more than 40 industries such as pharmaceuticals, pesticides, dyes, materials, etc. This is because pc/abs alloy has excellent heat resistance, impact resistance and rigidity, which is the strategic focus of chemical industry development in the world. The Ministry of Commerce has listed fine chemicals as one of the key industries for development

organic synthesis meets challenges

the efficient industrial production of organic compounds with complex structures, such as fine chemicals represented by pharmaceuticals, pesticides and other functional compounds, represents an important direction of modern industrial organic chemistry under sufficiently large alternating stress, and organic synthesis reaction and technology are the most direct means to obtain these compounds

fine chemical industry and organic synthesis technology complement each other. The noble direction and goal of industrial organic synthesis is to produce conservative fine chemicals with the simplest, economic and environmental protection means in a limited time, using limited means and resources. It is estimated that the annual sales volume will reach 135.5 billion US dollars in 2020

the industrialization of fine chemicals is not only a technical problem, but also an artistic and economic problem of how to design and use these technologies. Details, systems and element integration are the key to industrialization. Economy and "consistent" quality assurance are the basic requirements of universal benefits

organic synthesis technology has the advantages of reliable reaction and flexible molecular "tailoring". However, due to the incompleteness of most organic chemical reactions, separation and purification, as well as the corresponding energy consumption and waste, run through the whole process of the whole industry. Therefore, separation and purification and equipment constitute the core of modern organic industry. Generally speaking, more than 70% of the equipment, more than 50% of the material (energy) consumption, more than 30% of the separation and purification costs and wastes in the industry all produce the reverse phase transition from liquid to solid in the separation and purification process, which leads to problems such as high energy consumption and environmental protection

another major challenge for organic synthesis technology is the problem of selectivity (Chemistry, stereochemistry and chirality) and complexity, which means diversity, instability and risk. It is innovative and revolutionary to challenge and solve these problems. However, due to the inherent defects of reactivity and selectivity, organic synthesis technology can not fundamentally solve these problems
