Heptanoic anhydride (C₁₄H₂₆O₃), a niche chemical, has recently attracted attention for its cross-border applications. From the development of environmentally friendly materials to industrial auxiliaries, its multifunctional properties are driving innovative breakthroughs in the fields of environmental protection and chemicals.

　　Core Application Highlights

　　Environmentally friendly materials: replacing petroleum-based raw materials in the synthesis of low-carbon alkyd resins, helping to reduce VOC emissions from coatings by 30%; providing new solutions in the research and development of degradable plastics.

　　Industrial auxiliaries: applied to ore flotation agents, electronic chemicals and protective coatings for equipment, covering the mining industry, 5G and other industrial chains.

　　Market and Challenges

　　Global demand for heptanoic anhydride is expected to grow at an average annual rate of 4.5%, and China's production capacity share continues to rise. The industry needs to address safety risks such as corrosiveness and deliquescence, and promote confined production and process upgrading.
