Vacuum Rotary Evaporator For Catalytic Conversion Of Carbon Dioxide

ACHIEVE CHEM, together with the team from the School of Chemistry and Chemical Engineering of Xi'an Shiyou University, won the first prize of Science and Technology Progress Award for the achievement of "catalytic conversion of carbon dioxide to cyclic carbonate and polycarbonate".

As everyone knows, the persistent and massive emissions of carbon dioxide will cause environmental problems such as the reduction of the Antarctic ozone layer, global temperature rise, and the melting of polar glaciers, seriously endangering the health and survival of global organisms. How to reduce carbon dioxide emissions has become a global environmental issue of concern. Taking carbon dioxide as the basic raw material and transforming it into chemical products needed by human society through chemical methods can effectively consume carbon dioxide and realize the effective utilization of carbon resources. It is considered an effective way to solve the excessive emissions of carbon dioxide and meet the requirements of sustainable development, and has attracted extensive attention from Global studies.

In order to realize the effective transformation of carbon dioxide into high-value chemical products, ACHIEVE CHEM Ltd. and the team of the School of Chemistry and Chemical Engineering of Xi'an Petroleum University established the research topic of carbon dioxide to cyclic carbonate and polycarbonate transformation on the basis of previous research and a large number of literature research.

Both cyclic carbonates and polycarbonates are Green chemistry products and have important and extensive applications in many fields. However, the lack of efficient and stable catalysts restricts the implementation of large-scale synthesis of cyclic carbonates and polycarbonates. In response to this key challenge, the team has synthesized over forty transition or rare earth metal complex catalysts through scientific design and extensive experimental attempts by 50L high temperature high pressure reactor and laboratory vacuum rotary evaporator and other chemical supporting equipment. Multiple catalytic systems with high activity, high product selectivity, high stability, and easy recovery have been screened out, and the structure-catalytic performance relationship has been thoroughly and systematically studied. The design concept and synthesis technology of functional oriented complexes have been developed, This provides practical reference and theoretical guidance for the design and development of catalysts with better performance.

In response to the problem of poor thermal stability and mechanical properties of traditional polycarbonate, which limits its application, the research team has designed and developed multiple types of ternary copolymerized cross-linked polycarbonate. By improving the structural dimensions of polycarbonate, the thermal stability and mechanical properties of polycarbonate materials have been greatly improved, promoting the application and development of polycarbonate in chemical industry fields.

In addition, both teams have jointly developed polycarbonate materials with fluorescence recognition and flame retardant functions, further expanding the application scenarios of polycarbonate materials. It is worth noting that the team's partial research results on carbon dioxide to cyclic carbonates have entered the pilot stage.
