Recently, the Ministry of Industry and Information Technology released the **Recommended Catalogue of Energy-Saving and Carbon-Reduction Technologies and Equipment in the Industry and Information Technology Sector (2025 Edition)**. Donggeng’s independently developed \"high-purity melt crystallization technology\" was successfully included in this catalogue, marking its recognition at the ** level in the field of energy saving and carbon reduction in the fine chemical industry. The **Recommended Catalogue of Energy-Saving and Carbon-Reduction Technologies and Equipment in the Industrial and Information Technology Sectors (2025 Edition)** focuses on three main areas: energy-saving and carbon-reduction technologies for industry, such technologies for the information technology sector, and high-efficiency energy-saving equipment. It covers ten key industries including steel, petrochemicals, and building materials, as well as information technology applications such as data centers and communication stations. It includes a range of advanced technologies and equipment, thereby creating a coordinated system that combines technologies, equipment, and application scenarios. High-purity melt crystallization technology is one of the key technologies developed by Shanghai Donggeng Chemical Technology Co., Ltd. It is suitable for the purification of organic compounds, and relies on the theory of solid-liquid phase equilibrium to achieve selective crystallization and separation of the target components through precise temperature control. Currently, traditional distillation processes are widely used in the global field of separation and purification of high-purity chemicals, but they face challenges such as high energy consumption, large carbon emissions, and low efficiency in separating substances with similar boiling points. Compared to traditional distillation, Donggeng’s melt crystallization technology reduces energy consumption by 65%-85%, and enables the product purity to reach over 99.99% (with some cases achieving 99.999%). This technology fills a gap in China’s falling-film melting and crystallization industry, addressing various critical challenges related to the purification of high-purity chemicals and high-performance polymer monomers in the country. It has been successfully applied in areas such as lithium battery materials (carbonates), polymer monomers, refined naphthalene, and crySTALLine grade acrylic acid. There are over 20 patents related to Donggeng’s high-purity melt crystallization technology, including 4 granted invention patents, 5 domestic invention patent applications, and 1 European invention patent application ； 9 authorized utility models, 2 PCT applications. In addition, it has received numerous honors: it was designated as a \"Shanghai Standardization Pilot (Key) Project\" in 2023, made it onto the list of the \"Top 100 High-Tech Achievement Transformation Projects in Shanghai\" in 2024, and won the \"China International Industry Fair Excellent Product Award\" as well as the title of \"Patent-Intensive Product of 2024\". In 2025, it was included in the list of advanced processes, technologies, and equipment for the transformation and upgrading of the petrochemical industry issued by the China Petroleum and Chemical Industry Federation. It was also recognized as an outstanding technical achievement at the 2025 International Innovation Exhibition’s New Products and Technologies Presentation, awarded the 2025 CIIF Green and Low-Carbon Award, designated as a \"Recommended Technology for Low-Carbon Development in the Petrochemical Industry\" for 2025, won the Second Prize in the Patent category at the 5th Shanghai Intellectual Property Innovation Awards, received the 2025 Process Industry Innovation Award, and was included in the 14th batch of the \"Shanghai Innovative Products Recommendation List\".
