Breakthrough in key technology of norbornene derivatives

Investment, energy consumption and comprehensive costs were reduced by 41%, 30% and 20% respectively

Recently, the key technology development and application project of norbornene derivatives production led by the Institute of Chemistry Co.
, Ltd.
under the Henan Academy of Sciences broke through the key technical bottleneck of separation and use at home and abroad, realizing industrial production
.
Compared with the traditional process, the new process can reduce investment, energy consumption and comprehensive cost by 41%, 30% and 20%, respectively, and promote the technological progress of the norbornene industry

The project has won 7 invention patents, 1 utility model patent, formulated 9 group and corporate standards, and published 9 academic papers
.
Relevant experts believe that the key technology of norbornene derivatives has reached the international advanced level, which promotes the efficient use of mixed carbon five resources and enhances the core competitiveness of China's norbornene derivatives

According to Associate Researcher Yang Zhenqiang, the main completer of the project, after 12 years of technological development, transformation, and promotion and application, the project pioneered a new method of producing norbornene derivatives directly using mixed carbon five without separation, and built the first domestic set The norbornene derivative production device has created significant social and economic benefits
.

Yang Zhenqiang said that mixed carbon five is a by-product produced in the process of cracking to produce ethylene, and its components are complex.
Among them, cyclopentadiene is an important raw material for the preparation of norbornene derivatives
.
The boiling points of the components of the mixed carbon five are similar and easy to form azeotropes, which are difficult to separate by ordinary distillation methods.

In order to solve the technical problem of the difficult separation of norbornene, the Institute of Chemistry of Henan Academy of Sciences Co.
, Ltd.
established a scientific and technological research team.
Through the self-developed composite catalyst and ultra-low temperature reaction device, it invented the direct use of mixed carbon five to produce norbornene derivatives.
New method
.
"Compared with the traditional solvent extraction separation synthesis process, this process has the advantages of mild conditions, stable operation, convenient post-processing, and stable product quality.

It is understood that the project was jointly completed by the Henan Academy of Sciences Institute of Chemistry Co.
, Ltd.
, Puyang Huicheng Electronic Materials Co.
, Ltd.
, Zhengzhou University of Light Industry, and the Institute of Chemistry of the Chinese Academy of Sciences
