1. Chen Jing (1935-) graduated from the Department of Chemistry of Yunnan University on 1958. Precious metal metallurgy expert, academician of China Academy of Engineering, professor of Yunnan University. He has been engaged in the basic theoretical research of precious metal chemical metallurgy and its application for a long time, which has made great contributions to the establishment of extraction and separation methods of platinum group metals in China. In 1960' s, the regeneration and industrial test research of waste platinum catalytic net in nitric acid industry, which was urgently needed by our country, were completed. In the early 1980s, in the comprehensive utilization project of Jinchuan resources, the method of replacing and separating gold, palladium, platinum, rhodium and iridium with active copper powder was invented and successfully applied in production. Solved the technical problem of "separation and purification of rhodium and iridium"; It is suggested that the thermodynamic stability and kinetic inertia of heavy platinum group complexes are higher than those of light platinum group complexes. The classification rules of redox reaction, precipitation reaction, nucleophilic substitution reaction and solvent extraction of platinum group metal complex anions are summarized and put forward. 20 1 1 The arsenic pollution in Yangzonghai, Kunming was successfully controlled. He presided over more than 50 major scientific research tasks and won the first prize of national scientific and technological progress 1 item, the first prize of provincial and ministerial scientific and technological achievements 1 item, the second prize 1 item and the third prize. Won the honorary title of the first batch of national-level "young and middle-aged experts with outstanding contributions" and the honorary title of "Yunling model" in Yunnan Province. Enjoy special government allowance.

2. Zhang Guocheng (1931—)1952 entered the Department of Mining and Metallurgy, School of Engineering, Yunnan University. 1954 Kunming institute of technology was established by Yunnan university engineering college and other schools, so why did it transfer with the college? Rare earth metal smelting and separation expert, academician of China Academy of Engineering, senior engineer of Beijing Nonferrous Metals Research Institute. Long-term engaged in various rare earth concentrate smelting and single rare earth element separation research. The new process of oxidizing roasting-catalytic leaching for smelting bastnaesite has been successfully studied and widely promoted. A new process of smelting mixed rare earth concentrate by sulfuric acid enhanced roasting extraction method was invented, and the smelting concentrate amount was about 65438+ 10 thousand t/a; A new process of extracting and separating rare earth elements from rare earth sulfate solution with P204 extractant was successfully studied. New technologies such as alkaline production of fluorescent grade europium oxide, P204 extraction production of neodymium oxide and electrochemical oxidation and reduction of cerium and europium ions were invented, which were popularized in industry and achieved remarkable economic benefits. Won the second prize of National Science and Technology Progress Award, He Liang Heli Fund Excellent Patent Award 1 item and Science and Technology Progress Award 1 item. Won the honorary titles of "Young and Middle-aged Expert with Outstanding Contributions" and "Special Model Worker in Nonferrous Metal Industry System" awarded by the Ministry of Personnel. Enjoy special government allowance.

3. Sun Handong (1939 ——), 1962 graduated from the Department of Chemistry of Yunnan University, plant resources and phytochemist, academician of China Academy of Sciences, and researcher of Kunming Institute of Botany, Chinese Academy of Sciences. The resources and secondary metabolites of more than 200 plants in China, such as Rabdosia, Taxaceae, Schisandraceae, Umbelliferae, Lauraceae and lichen, were systematically studied. More than 1700 monomer compounds were separated and identified, and some new resources were found. More than 500 new skeletons and new types of compounds were found, of which more than 20 were of development and application value, which developed and enriched terpenoid chemistry. The structures of active components of Rabdosia rubescens A and Rabdosia rubescens A were discovered and clarified for the first time, and the chemical composition and biodiversity of Rabdosia rubescens were revealed, which promoted the wide development and application of Rabdosia rubescens as antibacterial, anti-inflammatory and anticancer drugs. Besides, drugs such as Aconitum chinense, new anthelmintics and pharynx Kang Shu have been developed, and the second-class new drug erigeron breviscapus injection for the treatment of cerebrovascular diseases has been applied for clinical research. Won the National Science and Technology Progress Award 1, the second prize of the Ministry of Science and Technology 1, and the third prize of China Academy of Sciences1; The first prize of Yunnan Natural Science Award 1, Yunnan Science and Technology Outstanding Contribution Award 1 (with a prize of 3 million yuan). Won the honorary titles of "National May 1st Labor Medal" and "Yunnan Province's first outstanding professional and technical personnel with outstanding contributions".

4. Hu Yongkang (1940-)1961graduated from the Department of Chemistry of Yunnan University. Expert in hydrocracking catalyst and hydrogenation technology, academician of China Academy of Engineering, and senior engineer of Fushun Petrochemical Research Institute of sinopec group. Mainly engaged in the research and development of hydrocracking catalyst and hydrogenation technology, once served as the head of the national key scientific and technological research project in the Sixth Five-Year Plan and the Seventh Five-Year Plan, and successfully developed two hydrocracking catalysts, 3825 light oil type and 3903 medium oil type, which filled the domestic gap and reached the level of similar advanced catalysts abroad, and have been used in 8 sets of industrial devices with a total processing capacity of 7.6 million tons/year, with remarkable economic benefits; During the "Eighth Five-Year Plan" period, the "Development of High Activity 3905 Catalyst" guided and participated in was superior to the first generation of light oil hydrocracking catalyst, and took a new step on the road of independent innovation. A variety of hydrocracking catalyst series and technologies have been successfully developed and popularized. Won the second prize of National Science and Technology Progress Award 1, the first prize of China Petrochemical Corporation, the second prize 1, and the third prize 4.
