Toxicity | LD50 orally in rats: 39 mg/kg (Smyth) |
A clear, colorless, flowable liquid that resembles the odor of ether. Freezing point -93 °c. Boiling point 97. The relative density was 0.772. Flash point 16.1 °c. Refractive index 3660. Soluble in water, alcohol, ether. Propionic acid is generated during hydrolysis and propylamine is generated during catalytic hydrogenation reduction. Flammable, toxic.
This product is used as a raw material, solvent and resin additive for organic synthesis. A small amount of medicine used as raw materials, the main synthetic antispasmodic 2,4, 6-trihydroxyphenylacetone and sulfamethoxazole and other drugs. It is also used as a standard substance for chromatographic analysis.
This product is toxic, and its toxicity is much stronger than that of hydrogen cyanide and acrylonitrile. Propionitrile, like other fatty nitriles, has an anesthetic effect on the central nervous system because it can be decomposed into hydrogen cyanide in the living body, thus stopping the respiration and oxidation of tissue cells and killing them. The oral LD50 of rats was 39mg/kg. Rabbit by subcutaneous injection LD50 is 210mg/kg. Production equipment should be closed, the operator should wear protective equipment.
This product is bottled, 150kg per barrel, canned, 14kg per can. This product is a Class I flammable liquid, stored and transported according to the hazard Code No. 61137.
