甲基丙烯酸 (MAA) - 高纯度丙烯酸单体

Methacrylic Acid (MAA) is an unsaturated carboxylic acid with the chemical formula C₄H₆O₂. It is a key raw material in the manufacturing of polymethyl methacrylate (PMMA), commonly known as acrylic or plexiglass, and is also used in coatings, adhesives, printing inks, and textile finishes.

在 卡文资源, 我们提供 technical-grade and industrial-grade MAA with ≥99% purity, ideal for use in polymerization, emulsion production, and water-based coatings. Our supply chain ensures prompt bulk shipments with consistent quality and international regulatory compliance.

⚙️ 生产方式

Acetone Cyanohydrin Route (ACH Process)

1. 丙酮 is converted into acetone cyanohydrin.

2. Hydrolysis and sulfuric acid treatment yield methacrylamide sulfate, which is then hydrolyzed to form MAA.

3. Distillation and purification follow to isolate high-purity methacrylic acid.

This process is widely used due to cost efficiency and scalability in industrial chemical synthesis.

❓ 常见问题（FAQ）

1. What’s the difference between Methacrylic Acid and Acrylic Acid?

请回答：
While both are unsaturated carboxylic acids, Methacrylic Acid has a methyl group on the alpha carbon, giving it greater stability and reactivity in certain polymerization reactions compared to Acrylic Acid.

2. Can MAA be used in water-based systems?

请回答：
Yes. MAA is often used in waterborne dispersions, especially in environmentally-friendly coatings and adhesives.

3. Is Methacrylic Acid hazardous?

请回答：
Yes. MAA is corrosive and flammable and must be handled with care. Proper PPE, storage, and ventilation are essential.

4. What certifications does Cavin Resource provide with this product?

请回答：
我们提供 COA (Certificate of Analysis), MSDS, UN/DOT labels, and if required, REACH compliance documents.
