Maleic Anhydride

Formula: C4H2O3 GOST/CAS: ГОСТ 11153-75, 108-31-6

Maleic anhydride is a multifunctional basic chemical product that serves as a crucial raw material for organic synthesis. Due to the presence of a double bond and an anhydride group, it possesses high reactivity and is an indispensable component in the production of a wide range of polymers, resins, additives, and agricultural chemicals.

Applications

Production of Unsaturated Polyester Resins (UPR): The main area of application. It is a base component for creating resins used in the production of fiberglass, artificial stone, automotive parts, and composite materials.

Paint and Varnish Industry: Used in the synthesis of alkyd resins. It improves the performance characteristics of paint and varnish materials, increasing the hardness, moisture resistance, and gloss of finished coatings.

Agrochemicals: Serves as an important intermediate for the synthesis of plant growth regulators, effective herbicides, fungicides, and insecticides (e.g., maleic hydrazide).

Additives and Plasticizers: Used to produce lubricating oils, dispersing additives for motor fuels, as well as in the production of eco-friendly plasticizers for PVC and other polymers.

Key Advantages

High Reactivity: Easily enters into polymerization, copolymerization, and addition reactions, making it a versatile building block for chemical synthesis.

Versatility of Application: A key component for obtaining numerous derivatives: malic, fumaric, and succinic acids, as well as tetrahydrofuran.

Consistently High Purity: The minimal content of impurities guarantees the stability and predictability of technological processes for the end consumer.

Cost-Effectiveness: An optimal ratio of reactive properties and cost, ideally suited for large-scale chemical production.

Storage & Transportation

Store in a cool, dry, well-ventilated area.
Strictly protect from moisture (upon contact with water, it gradually hydrolyzes into maleic acid).
Avoid contact with strong oxidizers, alkalis, and reducing agents.
Shelf life: 6 months from the date of manufacture when stored under proper conditions (for the solid form).
