Announcement on the Declaration of the 2020 Yunnan Provincial Science and Technology Award Project

　　According to the requirements for declaring the 2020 Science and Technology Award in the '2020 Yunnan Provincial Science and Technology Award Nomination Work Manual' issued by the Yunnan Provincial Department of Science and Technology, the company is announcing the project 'Application of the Patent for the Arsenic Removal Method of Yellow Phosphorus in the Production of Low-Arsenic Yellow Phosphorus Products'. The announcement period is from June 13, 2020, to June 19, 2020, for a total of 7 days. If there are any objections during the announcement period, please report to the company office.
　　I. Basic Information of the Project
　　1. Project Completion Unit: Yunnan Jianglin Group Co., Ltd.
　　2. Source of Task: Patent Transformation Implementation Plan of the Yunnan Provincial Intellectual Property Office
　　3. Name of Specific Plan: 'Application of the Patent for the Arsenic Removal Method of Yellow Phosphorus in the Production of Low-Arsenic Yellow Phosphorus Products'
　　4. Specific Plan Number: 2012-5304-03-000013
　　5. Project Start and End Date: July 25, 2012 - October 22, 2014
　　6. Project Achievement Registration Number: 1022015Y0025
　　7. Project Achievements: Established a 2000 tons/year low-arsenic yellow phosphorus production facility and obtained 3 invention patent authorizations.
　　II. Project Overview
　　Through years of research and development, the company has developed a new purification production process for arsenic removal from yellow phosphorus - the enhanced oxidation arsenic removal process: using aqueous oxidants at temperatures of 50°C-90°C under stirring conditions to fully contact with yellow phosphorus, oxidizing the arsenic in yellow phosphorus into soluble arsenic acid, thereby removing arsenic impurities from the yellow phosphorus phase into the aqueous phase, resulting in low-arsenic yellow phosphorus products. The aqueous oxidants consist of basic oxidants (such as: hydrogen peroxide, nitric acid, or one or more of hypochlorous acid) and oxidation enhancers (inorganic substances containing bromine such as: bromine, bromic acid, or one or more of bromates).
　　This process has the advantages of high arsenic removal rate, simple process, good economy, and safety, and has obtained authorization for a national invention patent in China. On this basis, the company independently undertook the patent transformation implementation project of the Yunnan Provincial Intellectual Property Office, conducting necessary research, discussion, and optimization of control parameters and equipment structure in the process through small-scale and pilot-scale tests, and established an industrial production facility with an annual output of 2000 tons of low-arsenic yellow phosphorus, with all control indicators and product indicators meeting the project's expected goals. The low-arsenic yellow phosphorus produced by this facility has been launched into the market and has received unanimous recognition from domestic and foreign users. The company's low-arsenic yellow phosphorus production facility is currently the only industrial facility of its kind in China. This facility has been operating stably for six years, with good operational conditions. As of December 31, 2019, it has produced and sold nearly 2500 tons of low-arsenic yellow phosphorus, achieving sales revenue of over 51 million yuan, profits of over 9 million yuan, and taxes of nearly 10.2 million yuan, resulting in good economic benefits.
　　III. Contribution of Candidates to the Project

　　IV. Intellectual Property Achievements
　　After the implementation of the project, 2 new authorized invention patents were obtained.
　　V. Major Scientific and Technological Achievements and Awards
　　The project won the second prize of the Yuxi City Science and Technology Award in 2015.
