3-bromo-propionitril - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | for organic synthesis. |
| Production method | It is obtained by the reaction of β-hydroxypropiononitrile and phosphorus tribromide. β-hydroxypropionitrile and phosphorus tribromide are added to benzene in a 3:1 molar ratio. After the reaction, the solvent benzene was evaporated. The reactants are then distilled under reduced pressure to collect the 68-69 ℃(0.93kPa) fraction, namely 3-bromopropionitrile. The yield is 43%. |
| category | toxic substances |

| acute toxicity | abdominal cavity-mouse LD50: 50 mg/kg |
| flammability hazard characteristics | open flame is combustible; high heat emits toxic bromide, nitrogen oxide and cyanide gas |
| storage and transportation characteristics | warehouse ventilation and low temperature drying; Store separately from oxidants, acids and food additives |
| fire extinguishing agent | foam, mist water, sand, carbon dioxide; Acid-base fire extinguishing agent |
