Methyl methacrylate (MMA) is a colorless, volatile liquid monomer with a characteristic odor. It is a key component in the production of polymethyl methacrylate (PMMA) (commonly known as acrylate) and various coatings, adhesives, and specialty polymers. With a global annual production capacity exceeding 4 million tons, MMA plays a vital role in industries such as automotive, construction, electronics, and healthcare.
What Is Methyl Methacrylate (CAS 80-62-6)?
Methyl methacrylate (MMA) is an unsaturated ester that has several uses in polymer manufacturing. It is a clear liquid with a characteristic ester odor.

Major Industrial Routes for MMA Production
Industrial production of MMA chemical is based on three main process routes, each with distinct advantages and limitations.
1. Acetone Cyanohydrin (ACH) Process
The ACH process is the most established and widely used technology.
Process Overview:
Acetone + Hydrogen Cyanide (HCN) → Acetone Cyanohydrin → MMA
Key Features:
Mature and reliable technology
High product purity (>99%)
Large-scale industrial application
Limitations:
Uses highly toxic hydrogen cyanide (HCN)
Generates ammonium sulfate as by-product
High environmental compliance requirements
Despite its drawbacks, the ACH process remains dominant due to its stability and proven industrial performance.
2. C4 Route (Isobutylene Route)
The C4 route produces MMA from isobutylene or tert-butanol.
Process Overview:
Isobutylene → Methacrolein → Methacrylic Acid → MMA
Key Features:
No cyanide usage (more environmentally friendly)
Lower hazardous waste generation
Suitable for regions with C4 feedstock availability
Challenges:
More complex catalytic system
Higher capital investment
Multi-step oxidation reactions
This route is increasingly adopted as industries move toward safer and greener production methods.
3. Ethylene-Based Route
The ethylene route is an emerging alternative integrated with petrochemical systems.
Process Overview:
Ethylene → Propionaldehyde → Methacrylic Acid → MMA
Key Features:
Utilizes widely available ethylene feedstock
Strong integration with refinery and petrochemical complexes
Potential for lower long-term cost
Limitations:
Less mature technology
Complex reaction pathways
This route represents a future-oriented solution for large integrated chemical plants.
Comparison of MMA Production Methods
| Process | Raw Materials | Advantages | Limitations |
|---|---|---|---|
| ACH Process | Acetone + HCN | High purity, proven | Toxic chemicals, waste |
| C4 Route | Isobutylene | No cyanide, cleaner | Multi-step oxidation |
| Bio-Based | Biomass | Eco-friendly | Not yet widely scaled |
