Isophthalonitrile FAQ
What is the shelf life of Isophthalonitrile?
When stored properly in its original packaging under recommended conditions (cool, dry place away from moisture and direct sunlight), Isophthalonitrile maintains its quality for at least 36 months from the production date. For optimal performance in sensitive applications, we recommend using the product within 24 months.
Can Isophthalonitrile be used in food contact applications?
Our standard Isophthalonitrile is not approved for food contact applications. We offer specialized food-grade versions that comply with relevant food safety regulations upon request. All food contact applications require specific certifications and testing to ensure compliance with regional food safety standards.
What are the main differences between Isophthalonitrile and Terephthalonitrile?
While both are aromatic dinitrile compounds, Isophthalonitrile (meta-position) and Terephthalonitrile (para-position) differ in their molecular structure orientation. This difference leads to distinct chemical properties: Isophthalonitrile generally has lower melting point, different solubility characteristics, and reacts differently in polymerization processes. The choice between them depends on the specific application requirements.
How should I dispose of Isophthalonitrile waste?
Isophthalonitrile waste should never be disposed of in regular trash or poured down drains. Follow all local, regional, and national regulations for hazardous chemical disposal. We recommend using licensed hazardous waste disposal services. Small quantities can be destroyed by incineration in approved facilities equipped with appropriate emission controls.
Can you provide customized particle size specifications for Isophthalonitrile?
Yes, we can produce Isophthalonitrile with customized particle size distributions to meet your specific application requirements. Our standard product has a D50 of 50-100 μm, but we can adjust milling parameters to achieve different particle size distributions (e.g., finer powders or controlled crystal habits) based on your technical specifications.
