Maleic Anhydride (MA), identified by its CAS number 108-31-6, is a highly reactive organic compound with a wide array of industrial applications. As a critical chemical intermediate, understanding its properties, safety considerations, and proper handling procedures is paramount for anyone working with this material. As a leading manufacturer and supplier, we are committed to providing our customers with the knowledge necessary to use our high-purity Maleic Anhydride safely and effectively. When you buy Maleic Anhydride, comprehensive information is as important as product quality.

Maleic Anhydride typically presents as a white, crystalline solid, often in flake or briquette form, possessing a characteristic acrid odor. Its chemical formula is C4H2O3, with a molecular weight of 98.06 g/mol. Key physicochemical properties include a melting point around 53-58°C and a boiling point of approximately 202°C. It is soluble in water, where it hydrolyzes to maleic acid, and also dissolves in various organic solvents like ethanol, ether, and acetone. Its reactivity stems from the anhydride group and the carbon-carbon double bond, making it a versatile building block in organic synthesis.

Safety is a primary concern when handling Maleic Anhydride. It is classified as harmful if swallowed and corrosive to the skin and respiratory tract. Exposure can cause severe skin burns and eye damage, and inhalation may lead to allergic reactions or asthma symptoms. It can also cause damage to organs through prolonged or repeated exposure. Therefore, strict adherence to safety protocols is essential. This includes wearing appropriate personal protective equipment (PPE) such as chemical-resistant gloves, safety goggles or face shields, and respiratory protection in areas with potential dust or vapor exposure. Always ensure adequate ventilation.

Proper handling and storage procedures are critical to maintaining product integrity and ensuring safety. Maleic Anhydride is moisture-sensitive and should be stored in a cool, dry, well-ventilated area away from incompatible materials. Incompatibilities include strong oxidizing agents, bases (like sodium hydroxide), alkali metals, and amines, which can react vigorously or even explosively with MA, especially at elevated temperatures. Containers should be kept tightly closed to prevent moisture absorption and contamination. Grounding and bonding of equipment during transfer operations are recommended to prevent static discharge.

Our commitment as a manufacturer and supplier extends to providing detailed safety information, including Material Safety Data Sheets (MSDS), to all our customers. We ensure that our Maleic Anhydride is produced under strict quality controls to maintain its purity, typically above 99.5%, which is vital for its downstream applications in resins, coatings, pharmaceuticals, and agrochemicals. Understanding these properties and safety guidelines is crucial for anyone involved in its use.
