Product Description of Acrylonitrile CAS#107‑13‑1
Acrylonitrile is a colorless, flammable liquid. Its vapor forms explosive mixtures with open flames. As a high‑volume synthetic unsaturated nitrile with growing market demand, it does not exist in nature.
It serves as a key chemical intermediate. Main applications cover acrylic/modacrylic fibers, high‑impact ABS and SAN plastics, synthetic rubber, pharmaceuticals, antioxidants and dyes. SAN resins are widely applied in auto parts, household goods, packaging and construction. It can produce adiponitrile for nylon manufacturing. Its historical use as pesticide fumigant has been fully discontinued.

Product Application Of Acrylonitrile CAS#107‑13‑1
Acrylonitrile is applied for acrylic‑fiber, resin and surface‑coating manufacturing. It serves as chemical intermediate for pharmaceuticals and dyes, and functions as polymer modifier. Its old fumigant usage has been phased out. During combustion or pyrolysis of polyacrylonitrile‑based materials, acrylonitrile may release in fire flue gas. Residual acrylonitrile monomer inside ABS/SAN copolymer containers can migrate into food‑simulating solvents; higher temperature accelerates such migration.
Product Basic Information
Basic Identifiers
Product Name: Acrylonitrile
Synonyms: Propenitrile, Vinyl cyanide, Cyanoethylene
CAS: 107‑13‑1
MF: C₃H₃N
MW: 53.06
EINECS: 203‑466‑5
Appearance: Colorless transparent volatile liquid
MOQ: 1 FCL (Full Container Load)
Chemical & Physical Properties
Boiling point: 77.3 °C
Density: 0.806 g/mL (25 °C)
Flash point: −1 °C
Stability: Easy self‑polymerization; stabilizer is mandatory for storage
Hazard: Highly flammable and toxic; vapor‑air mixture is explosive
Production Preparation Method
Industrial acrylonitrile is mainly produced by propylene ammoxidation. After catalytic reaction, crude material goes through quenching, absorption and rectification purification. Polymerization inhibitor is added to prevent polymerization in storage and transit.
Detailed Application Scenarios
Synthetic Fiber & Resin Manufacturing
Key raw material for acrylic fiber, ABS and SAN engineering resins, widely used for household goods, packaging and auto parts.
Surface Coating Industry
Used as monomer raw material for certain surface‑coating formulations.
Fine‑chemical Intermediate
Applied for synthesis of pharmaceutical intermediates and dyes; also acts as polymer‑performance modifier.
Note: Its historical fumigant application has been fully discontinued.
Material‑safety Reference
Polyacrylonitrile‑containing materials may release acrylonitrile under high‑temperature pyrolysis or fire conditions. Residual monomer inside ABS/SAN plastic products can migrate into contact media; temperature rise speeds‑up migration.
Upstream & Downstream Product Information

FAQ Frequently Asked Questions
Q1: Why must acrylonitrile add stabilizer?
A: It tends to self‑polymerize under heat and light. Stabilizer suppresses polymerization and prevents container blockage.
Q2: Can acrylonitrile be used as fumigant?
A: No, fumigant‑related usage has been completely eliminated.
Q3: What causes acrylonitrile migration from plastic containers?
A: Unreacted residual monomer inside ABS / SAN polymer will migrate into contacting solvents, and higher temperature accelerates this migration.
Q4: Shelf‑life?
A: 6 months under original sealed, cool‑dark storage environment.
