High - functionalization will become the general trend of chemical industry development

"Convergence", "crossover", "crossover", "collaborative innovation"... These words became "high-frequency words" among experts at the 619th academic discussion of the xiangshan science conference recently.

Experts believe that the large-scale development and utilization of fossil resources makes the ecological environment continuously deteriorate, which is an unavoidable problem in chemical industry, and the concept of green and low-carbon development has gradually become a consensus. "This has promoted the continuous intersection, penetration and integration of chemical and other disciplines, presenting a new vision of collaborative innovation and development." "Said he mingyuan, an academician at the Chinese academy of petrochemical sciences and one of the executive chairmen of the meeting.

Li jinghai, a member of the Chinese academy of sciences, said that the cross-integration and collaborative development of chemical and chemical disciplines requires an in-depth understanding of the mesoscale time-space complex structure at different levels and the realization of the correlation between levels.

Some of China's achievements in chemical and chemical sciences have led the world. "The number of papers, citations, per paper citations, highly cited papers and Nature Index in the field of chemistry and chemical engineering are among the best in the world." He mingyuan academician pointed out.

However, compared with the booming chemical science, the development of chemical industry is a little slow, "many core technologies are still not owned, and the self-developed industrial process grows slowly. "There is still a gap between domestic and foreign products, especially in the middle and high-end market, where the market share is low," he said.

Data on the import and export trade of the petroleum and chemical industries in China, released by the China petroleum and chemical industry federation in February this year, show that domestic products are uncompetitive. In 2017, the total trade volume of the whole industry was 583.37 billion us dollars, of which the export volume was 192.98 billion us dollars, with a deficit of 19.742 billion us dollars, expanding by 45.1% year-on-year.

"In this sense, the development of chemical science and technology is unbalanced to some extent, and technology has not kept pace with the pace of science." Academician he mingyuan emphasized.

Meanwhile, according to peng xiaojun, an academician at dalian university of technology, fine chemicals have accounted for more than 65 percent of chemical industry output in developed countries, while only about 40 percent in China. The main problems are as follows: first, the product performance is low, the products with independent intellectual property rights are few, and the international competitiveness is lacking; Second, environmental pollution has become the main constraint factor for sustainable development, which requires the development of clean, low-energy and low-consumption preparation technology.

Throughout the development of international chemical industry and products, high function, green and intelligent become the general trend. The key to high functionalization is the relationship between structure and performance, while the key to greening is the clean, safe and controllable preparation process. The way to achieve high functionalization and greening is "intelligentization", including the intelligentization of product functions and intelligent control preparation. Academician he mingyuan pointed out that green chemistry is the only way for the coordinated development of chemical and chemical science and technology. In terms of chemical and chemical technology, it is not only the "green" of the process itself, but also covers the supply side, the demand side, the inlet side, the outlet side and even the whole life cycle of the product.
