Breakthrough in Synthesis Technology of Carbon Dioxide Acrylate: A New Chapter in Green Chemistry

under the background of global climate change, the capture and utilization of carbon dioxide (CO₂) has become a hot field of scientific research and industry. As an important industrial raw material, acrylate is widely used in coatings, adhesives, textile finishing agents and other fields. How to convert CO₂ into high value-added chemicals, especially acrylate compounds, not only helps to realize the efficient use of carbon resources, but also reduces the dependence on traditional petrochemical resources and promotes the development of green chemistry. In recent years, the synthesis technology of carbon dioxide based acrylate has made an important breakthrough, which has injected new vitality into the research and industrial application in this field.

1. Carbon Dioxide Acrylate Synthesis Technology Background and Significance

The synthesis of carbon dioxide-based acrylate refers to the chemical reaction of CO₂ with propylene oxide and other reactants to generate acrylate compounds. This process can not only effectively use CO₂, but also reduce the consumption of petroleum resources and environmental pollution in traditional processes. As a typical "green chemistry" technology, the conversion and utilization of carbon dioxide conforms to the concept of sustainable development, and also provides a new way to solve the problem of greenhouse gas emissions.

The traditional acrylate production process mainly relies on petrochemical raw materials, such as the preparation of acrylate from propylene and propionic acid. This production method not only has high energy consumption and high cost, but also causes great pressure on the environment. In contrast, the synthesis technology of carbon dioxide-based acrylate has the characteristics of abundant raw materials, green, non-toxic, and environmentally friendly. It is one of the important ways to achieve the goal of carbon neutrality.

2. carbon dioxide based acrylate synthesis technology status and challenges

At present, the synthesis technology of carbon dioxide based acrylate mainly includes two technical routes: direct method and indirect method.

1. Direct method: Direct method refers to the direct reaction of CO₂ with propylene oxide under the action of a catalyst to produce acrylate. This method has the advantages of simple process and few steps, but the reaction conditions are harsh, usually requires a high temperature and high pressure environment, and the efficiency and stability of the catalyst still need to be improved.

2. Indirect method: Indirect method is to first convert CO₂ into other intermediate products, such as urea or carbonate, and then react with propylene oxide to form acrylate. The reaction conditions of this method are relatively mild, but there are many intermediate steps, which increase the production cost and energy consumption.

Although these two methods have made some progress, the current carbon dioxide based acrylate synthesis technology still faces some key bottlenecks. For example, how to improve the yield and selectivity of the reaction, how to reduce the energy consumption and cost of the reaction, and how to develop an efficient and stable catalyst system are all problems that researchers need to focus on.

3. Carbon Dioxide Acrylate Synthesis Technology Breakthrough and Innovation

In recent years, scientists have made a series of important breakthroughs in the synthesis technology of carbon dioxide-based acrylate, which provides a new direction for the research and industrial application in this field.

1. Development of high-efficiency catalysts: The catalyst is a key factor affecting the efficiency and selectivity of the reaction. By developing new metal catalysts or transition metal oxide catalysts, the researchers have significantly improved the reaction activity of carbon dioxide and propylene oxide, and reduced the requirements of reaction conditions. For example, supported palladium catalysts or copper-based catalysts have been shown to enable high yield acrylate synthesis under certain conditions.

2. Optimization of reaction conditions: by optimizing the reaction temperature, pressure, pH and other conditions, scientists have successfully realized the efficient synthesis of carbon dioxide based acrylate. For example, by controlling the reaction temperature in a lower range, not only the energy consumption is reduced, but also the purity and stability of the product are improved.

3. Innovation in green processes: Some research teams have tried to introduce electrochemical or photocatalytic techniques into the synthesis of carbon dioxide-based acrylates. For example, the use of renewable energy-driven electrochemical reduction reaction, the efficient conversion of CO₂ into acrylate, to achieve the clean use of energy.

These technological breakthroughs not only improve the synthesis efficiency of carbon dioxide-based acrylate, but also lay a solid foundation for its industrial production.

4. carbon dioxide based acrylate synthesis technology in the future

In the future, with the further development of carbon dioxide-based acrylate synthesis technology, its potential in industrial applications will be more fully released. On the one hand, researchers will continue to devote themselves to the development of efficient and low-cost catalyst systems, optimize the reaction process, and further reduce production costs; on the other hand, the application fields of carbon dioxide-based acrylates will continue to expand, such as in biodegradable materials, environmental protection Coatings and other fields show broad prospects.

With the increasing attention to green chemistry and sustainable development worldwide, the synthesis technology of carbon dioxide based acrylate will continue to receive policy and funding support. Through the close cooperation of production, learning and research, this technology is expected to achieve large-scale industrial application in the future, contributing to the realization of carbon neutrality and the construction of green chemical industry.

The breakthrough of synthesis technology of carbon dioxide based acrylate is not only an important progress in the field of green chemistry, but also provides a new idea for the efficient utilization and sustainable development of CO₂. Although there are still some technical and economic challenges, with the deepening of research and technological innovation, the prospect of industrial application of this technology will be broader. As practitioners in the chemical industry, we have reason to believe that the synthesis technology of carbon dioxide-based acrylate will become an important engine to promote the development of green chemistry and inject new impetus into the sustainable development of human society.
