There are 16 authorized patents, including 8 invention patents and 8 utility model patents.   In 2020, we successfully won the major scientific and technological achievements transformation project in Hebei Province, and received 4 million yuan of direct scientific research funds; we cooperated with China National Chemical Bluestar Chenguang Chemical Research Institute to become a sub-center of the National Engineering Plastics Engineering Research Center; at the same time, we will strengthen cooperation with universities and colleges. It has signed long-term technical cooperation agreements with Tsinghua University, Tianjin University, Anshan Iron and Steel Design Institute, and the Second Institute of Chemical Technology to enhance the scientific research and technical strength of the enterprise.   We are setting up a research pilot base and a research building in the factory area of ​​Xinnuo Lixing (Cangzhou Bohai New Area) Chemical Co., Ltd. By promoting the construction of the research and development platform, we have laid a solid foundation for improving the technological content of the company's products and accelerating the transformation of scientific research results. We plan to use 3-5 years to build a high-tech, high-value-added new chemical material industry cluster in Cangzhou and even the Beijing-Tianjin-Hebei region.   Brief introduction of key industrial chain and project construction plan: (1) Quinoline series industry chain: quinoline in washing oil is used as a raw material for the production of important pharmaceutical and pesticide intermediates, and is used to prepare niacin and hydroxyquinoline drugs. At present, the 1,000-ton/year quinolinic acid and 500-ton/year 8-hydroxyquinoline projects constructed in Lingang Fengya Chemical Industry have reached production and effective, and the market acceptance is good. Each year, it can increase sales revenue of 500 million yuan and profit of 100 million yuan for enterprises.   (2) Fluorene series industry chain: Fluorene in washing oil is used as a raw material for the production of important pharmaceutical and resin intermediates, and is used to prepare polymer pharmaceuticals and resin materials. This project belongs to the market vacancy project.   At present, the construction of the 1200t/a 9-fluorenone project in Lingang Fengyahua has been completed; the industrial production of XN060, XN061, XN065 and XN067 has been completed in the company's headquarters (Luqiao Industrial Zone), realizing the realization of fluorene-based structural optics The localization of resin monomers breaks the foreign technology blockade and fills the market gap. Fluorene-based optical resins are widely used in high-end materials such as ultra-thin spectacle lenses, mobile phone lenses, cameras, and photoresists, contributing to high-performance optics in my country. The rapid development of the resin material industry. In the next step, Fengya will invest 500 million yuan to build a new material project of fluorene series, which can increase the company's sales revenue by 500 million yuan and profit by 100 million yuan every year.   (3) Oxyfluorene industry chain: Oxyfluorene in washing oil, as a raw material for the production of important fine chemical intermediates, can be used to prepare high-end synthetic resins and new polymer materials. This project belongs to the high-end optical material project.   O-phenylphenol (OPP) prepared from oxyfluorene is widely used as an important new fine chemical product in the fields of bactericidal and antiseptic, surfactant and printing and dyeing auxiliaries. Resin (OPPEA) and environmentally friendly flame retardants (DOPO) of polymer materials have extremely broad application prospects and excellent economic value, and belong to high-end optical material projects. In 2022, 800 million yuan will be invested in the construction of oxygen fluorene deep processing and power station, scientific research pilot test, office area and supporting facilities. It is planned to start construction in July 2022 and trial production in July next year. By then, the company can increase sales revenue by 1 billion yuan and profit by 500 million yuan every year.   (4) Accenaphthene series industry chain: As the raw material of 1,8-naphthalene dicarboxylic anhydride, acenaphthene in the washing oil can be used for the preparation of dyes and the preparation of new special engineering materials. This project is a pioneer in the field of new chemical materials. The "stuck neck" project has applied for its own intellectual property rights.   A new type of special engineering material polyethylene naphthalate (PEN) is prepared by deep processing of acenaphthene. PEN is a new chemical material advocated by my country's 14th Five-Year Plan, but its industrialization technology is in the hands of international chemical giants such as Japan's Teijin, Toray, and British ICI. As an enterprise development reserve project, the PEN project will invest 2 billion yuan in the construction of polyethylene naphthalate and downstream product projects in the next three years, which will increase the company's annual sales revenue by 2 billion and 500 million in profits.   (5) Phthalic anhydride industry chain: Phthalic anhydride, as an important organic chemical intermediate, can be used not only in the manufacture of environmentally friendly plasticizers, resin production, but also in the preparation of new degradable plastics. This project belongs to the comprehensive utilization of carbon dioxide that the state encourages to develop. New material project.   Polypropylene carbonate (PPC), which is copolymerized with phthalic anhydride, carbon dioxide and propylene oxide, is a completely degradable and environmentally friendly plastic, which responds to the national strategic plan of carbon peaking, carbon neutrality and green sustainable development. Polypropylene carbonate has excellent properties, including light transmittance, degradability, high barrier properties and ultra-high foaming ratio, etc. It can replace plexiglass, PVC, PLA and other materials, mainly used in film, medical, food packaging, etc. It has huge market development space.   Polypropylene carbonate (PPC) is an extension of our company's existing product chain. It has a great cost advantage and can consume 50,000 tons of carbon dioxide every year. It is at the forefront of neutralization and carbon peaking.   This project is a fundraising and investment project for the listing of the company. After listing, it plans to invest 1.5 billion yuan to build polypropylene carbonate, integrated logistics, and phthalic anhydride projects. It is planned to start construction in August 2023. By then, the company can increase sales revenue by 1.5 billion and profit by 300 million annually.   In addition, in the Luqiao base, the 300,000-ton/year tar processing, 50,000-ton/year washing oil processing, and 300,000-ton marine fuel oil projects are in process. 200 million profit.   In terms of total economic volume, in the next 3-5 years, Cigna Lixing Group will become a large-scale enterprise with sales revenue exceeding 10 billion yuan and annual profits and taxes exceeding 3 billion yuan.
