Acrylonitrile is a high-volume industrial monomer whose value is closely connected to the performance of its downstream polymers. The molecule combines a polymerizable vinyl group with a polar nitrile group, making it useful in copolymers and intermediates where chemical resistance, rigidity, oil resistance or fiber-forming behavior is required.
ABS and SAN engineering resins
In acrylonitrile-butadiene-styrene resin, the acrylonitrile component contributes chemical resistance, heat performance and dimensional stability, while the other monomers contribute toughness and processability. ABS is used in automotive components, appliances, electronics, construction products and consumer goods. Styrene-acrylonitrile resin is selected for rigidity, transparency and chemical resistance in suitable applications.
Acrylic fibers and PAN materials
Acrylonitrile is the principal monomer used to manufacture acrylic fibers. These fibers are valued for softness, warmth, weather resistance and textile performance. Polyacrylonitrile is also an important precursor family for carbon-fiber production, where precursor composition and processing strongly influence the final material.
Nitrile rubber
Nitrile-butadiene rubber uses acrylonitrile to improve resistance to oils and fuels. NBR is commonly found in hoses, seals, gaskets, protective gloves, rollers and adhesives. Different acrylonitrile contents can change the balance between oil resistance, flexibility and low-temperature behavior.
Acrylamide and other intermediates
Acrylonitrile is a key raw material for acrylamide, which is further used to produce polyacrylamide. Polyacrylamide supports water treatment, paper manufacturing, mining and other separation or viscosity-control applications. Acrylonitrile also participates in selected routes to adiponitrile and specialty nitrile derivatives.
Why monomer quality matters
Downstream users should evaluate more than the headline assay. Water, acidity, color, inhibitor level, metals and trace organic impurities can affect storage stability or process performance. A representative specification and batch COA should be reviewed before commercial qualification.
For grade, purity and document inquiries, visit the Acrylonitrile CAS 107-13-1 product page.
Conclusion
Acrylonitrile connects several important material chains: engineering plastics, fibers, rubber, water-treatment intermediates and high-performance PAN-based materials. Application-specific specification review is essential because each downstream process can respond differently to monomer impurities and stabilization.
Technical context for applications in ABS, acrylic fibre, NBR and PAN-based materials
Acrylonitrile is a reactive, volatile nitrile monomer. Industrial supply is commonly stabilized, and the inhibitor or stabilization system must be understood together with storage time, temperature, contamination control and downstream polymerization requirements.
In ABS production, acrylonitrile contributes chemical resistance and related performance attributes; in acrylic fibre and PAN routes it is the principal nitrile monomer; in NBR it is copolymerized to provide oil- and fuel-resistance characteristics. Exact formulations and operating conditions remain process-specific.
Commercial approval should connect the intended application with a written specification. A product name, CAS number or headline purity is not enough to define grade, physical form, impurity limits, analytical basis, packaging or suitability for a regulated end use.
Parameters to put into the purchase specification
| No. | Review point | Buyer action |
|---|---|---|
| 1 | monomer assay and trace impurity profile | Define a numeric limit, unit and method where critical. |
| 2 | water content for the receiving process | Define a numeric limit, unit and method where critical. |
| 3 | stabilizer status and storage history | Define a numeric limit, unit and method where critical. |
| 4 | colour and appearance | Confirm before order release and batch shipment. |
| 5 | trial performance in the approved polymerization system | Confirm before order release and batch shipment. |
The parameters should be read together. A satisfactory assay cannot compensate for excessive water, unsuitable solvent concentration, incorrect stabilizer status or a packaging system that does not protect the material. When two suppliers use different methods, compare sample preparation, calculation basis, reporting unit and detection limit before comparing the results.
Sample qualification and batch release
Before a first commercial order, request the current specification, a representative COA and SDS, then test a representative sample under the receiving plant’s approved method. Where reaction performance is critical, complete a controlled laboratory or pilot trial and document conversion, selectivity, colour, residue or other application-specific results.
For the shipping batch, request the actual batch COA and verify product name, CAS number, lot number, manufacture date where applicable, package count and net weight. Retain a receiving sample according to the buyer’s quality system so that any later investigation can compare the delivered material with the production record.
Storage, handling and logistics boundaries
The current SDS and site-specific exposure controls are essential. NIOSH identifies acrylonitrile as a substance requiring stringent occupational control; the product should therefore be handled only by trained industrial users with appropriate engineering controls and emergency planning.
For international orders, transport classification, UN information, packing group, port acceptance, carrier requirements and destination controls must be confirmed from the current shipping documents. These details can depend on concentration, solvent, package and route. The supplier and importer should resolve them before booking freight, not after material reaches the port.
Questions for supplier qualification
- Is the quoted form, concentration and assay basis identical to the approved specification?
- Which methods are used for the critical parameters and what are their reporting limits?
- Can a representative COA, SDS and sample be supplied before the first order?
- How are moisture, contamination and package integrity controlled before shipment?
- Which export and dangerous-goods documents are available for the proposed route?
- How are batch changes, specification changes and non-conforming results communicated?
Common purchasing mistakes
Frequent mistakes include comparing products on purity alone, confusing active content with total solution concentration, accepting a typical COA as the shipping-batch result, leaving package selection until after the quotation, and assuming that an application mentioned online proves fit-for-use. These risks are reduced by one controlled specification, a sample approval record and clear responsibility for documents and receiving inspection.
Product page and quotation request
Review the current Acrylonitrile product page for CAS 107-13-1. To request a meaningful quotation, provide the required form and concentration, target specification, quantity, package preference, application, destination port or country, and required documents. Xinchen can then review availability and export feasibility without implying suitability beyond the documented grade.
