1.Basic Overview
Acrylic acid (CAS No. 79-10-7) is a widely used unsaturated carboxylic acid in the chemical industry, serving as a foundational building block for producing acrylate esters and a broad range of polymer materials.
Its molecular formula is C₃H₄O₂, with the structural formula CH₂=CHCOOH. Under standard conditions, it appears as a clear, colorless liquid with a sharp, pungent odor.
For commercial supply, acrylic acid is always provided in stabilized form to prevent unwanted polymerization during storage and transportation. In international trade, the term glacial acrylic acid is commonly used, referring to high-purity acrylic acid intended for industrial processing applications.
2.Properties and Product Classification
Chemically, acrylic acid contains both a carbon-carbon double bond and a carboxyl group, enabling it to undergo polymerization and esterification reactions — a key reason for its extensive industrial utility.
The key information includes:
Molecular formula: C₃H₄O₂
Structural formula: CH₂=CHCOOH
CAS No. : 79-10-7
Molecular weight: 72.06 g/mol
Boiling point: ~141°C
Melting point: ~13°C
Density: ~1.04 g/cm³
In global bulk trade, acrylic acid is primarily categorized by purity grade, not laboratory-style grades. The dominant commercial form is:
Glacial Acrylic Acid (GAA): High-purity industrial-grade acrylic acid (typically ≥99.5% purity), used in polymer production and acrylate manufacturing.
This classification reflects real-world procurement practices, where GAA is the standard form traded for most industrial applications.
3.Typical Quality Specifications
For industrial buyers, the Certificate of Analysis (COA) is more critical than general descriptions, as it directly verifies product consistency and suitability for downstream use.
A typical specification range for commercial-grade acrylic acid is as follows:
|
Item |
Specification |
|
Appearance |
Clear, colorless liquid |
|
Assay (as Acrylic Acid) |
≥ 99.5% |
|
Color (Pt-Co) |
≤ 10 |
|
Water Content |
≤ 0.20% |
|
Inhibitor (MEHQ) |
180–220 ppm |
|
Aldehyde Content |
≤ 0.05% |
These parameters are widely adopted in international trade, ensuring storage stability and compatibility with downstream reactions.
4.Downstream Product: Polyacrylic Acid
One common question from industrial buyers is: What is polyacrylic acid? As a key derivative of acrylic acid, it is widely used in water treatment, superabsorbent polymers and personal care formulations.
Polyacrylic acid is produced via the polymerization of acrylic acid. It is valued for its particle-dispersing, viscosity-controlling, and water-absorbing properties, leading to widespread use across industries.
Typical applications include:
Water treatment chemicals
Superabsorbent polymers (SAPs)
Personal care formulations
When customers require a polyacrylic acid SDS, they are primarily verifying regulatory compliance and application suitability. We can provide full, updated SDS and compliance documentation upon request to support your evaluation and production needs.
5.Main Applications and Market Use
Acrylic acid demand is driven by several key industrial sectors:
Acrylate esters production (largest share): Including butyl acrylate, ethyl acrylate, and methyl acrylate, which are used in coatings, adhesives, and textile processing. This is why terms like "prices of acrylic acid and its acrylate esters" are commonly searched by buyers monitoring raw material costs.
Superabsorbent polymers (SAPs): Used in hygiene products and agricultural water-retention materials.
Coatings and construction materials: Acrylic-based systems offer enhanced durability and environmental resistance.
Some search terms, such as "acid free primer for acrylic nails," relate to downstream formulated products. In these cases, acrylic acid is not used directly but serves as a raw material for intermediate derivatives.
6.Supply Situation and Sourcing Considerations
The supply of acrylic acid is closely tied to propylene feedstocks, as it is primarily produced via two-stage oxidation of propylene. As a result, pricing and availability often fluctuate with upstream petrochemical market conditions.
