丙烯腈 Detection
Formula C₃H₃N · CAS 107-13-1 · 致癌物（IARC 2B 类）/ 剧毒 / 可燃
Hazards & Toxic Symptoms
Acrylonitrile is a colorless or light yellow volatile liquid, with highly toxic vapor. It can be absorbed through the skin and respiratory tract. Metabolism in the body produces cyanide, leading to tissue hypoxia. Prolonged exposure increases the risk of cancer.
Occupational Exposure Limits (GBZ 2.1-2019)
| PC-TWA (Time-Weighted Average) | 1 mg/m³ |
|---|---|
| PC-STEL (Short-Term Exposure) | 2 mg/m³ |
| IDLH (Immediately Dangerous to Life or Health) | 85 ppm |
| LEL (Lower Explosive Limit) | 3.0% |
| UEL (Upper Explosive Limit) | 17.0% |
