Physical property


Physical and chemical properties: colorless, light ammonia flavor liquid. Molecular formula C3H7NO, molecular weight 73.10, relative density 0.9445 (25 C), melting point - 61 C, boiling point 152.8 C, flash point 57.78 C. The vapor density is 2.51, the vapor pressure is 0.49kpa (3.7mmHg 25 C), and the spontaneous combustion point is 445 C. The refractive index is 1.42817, and the solubility parameter is =12.1. The explosion limit of steam and air mixture is 2.2-15.2%. Mixed with water and usually organic solvents, mixed with petroleum ether. Fire and explosion can be caused by open fire and high heat. It can react violently with concentrated sulfuric acid and fuming nitric acid or even explode. Hazard marker 7 (flammable liquid) is mainly used as an industrial solvent, in the pharmaceutical industry for the production of vitamins, hormones, and also for the manufacture of pesticides.
