Basic Information
Product Name: 1-Nitropropane
Chemical Formula: C3H7NO2
Molar Mass: 89.09 g/mol
CAS Number: 108-03-2
Physical Properties
Appearance: Colorless transparent liquid with a chloroform-like odor.
Melting Point: -108.5°C
Boiling Point: 131-132°C
Density: 1.00 g/mL (at 20°C)
Solubility: Slightly soluble in water (≈1.7 g/100 mL, 20°C); highly soluble in organic solvents like ethanol, diethyl ether, and chloroform.
Volatility: Volatile; vapor density is higher than air (3.07 g/L, air=1).
Chemical Properties
Flammability
Vapors can form explosive mixtures with air (explosive limit: 1.4%-7.1% by volume). Combustible when exposed to open flame or high heat.
Combustion products: CO2, NOx (toxic nitrogen oxides).
Reactivity of Nitro Group
Acidity: The α-hydrogen exhibits weak acidity due to the electron-withdrawing effect of the nitro group, reacting with strong bases (e.g., NaOH) to form nitropropane salts.
Reduction: Under strong reducing agents (e.g., Fe/HCl, Sn/HCl), the nitro group is reduced to an amino group, yielding 1-aminopropane (propylamine).
Nucleophilic Substitution: The β-hydrogen can be substituted by nucleophiles (e.g., cyanide, alkoxides) due to the nitro group's electron-withdrawing effect, facilitating the synthesis of complex organic molecules.
Reaction with Metals
Contact with alkali metals (e.g., sodium, potassium) may trigger violent reactions; avoid mixed storage.
Applications
Solvent
High-boiling polar solvent for dissolving cellulose esters, resins, paints, and inks.
Substitutes some halogenated solvents (e.g., chloroform) in organic synthesis and extraction processes.
Organic Synthesis Intermediate
Pharmaceuticals: Used in synthesizing anti-arrhythmic drugs and antibiotic intermediates.
Pesticides: Precursor for insecticides and herbicides (e.g., nitroolefin compounds).
Polymers: Nitro groups are reduced to amino groups for synthesizing polyamides, polyurethanes, etc.
Fuel Additive
Improves the cetane number of diesel fuel in small amounts (with controlled toxicity risks).
Analytical Chemistry
Serves as a stationary phase or solvent in gas chromatography (GC) for separating polar compounds.
Safety and Protection
Toxicity:
Acute Toxicity: Oral LD50 in rats ≈910 mg/kg (low toxicity), but vapors irritate the eyes and respiratory tract. High inhalation may cause headache, nausea, and vomiting.
Chronic Effects: Prolonged exposure may damage the liver and nervous system; not classified as a carcinogen by IARC.
Protective Measures:
Respiratory Protection: Use a organic vapor cartridge in poorly ventilated areas.
Skin/Eye Protection: Wear chemical-resistant gloves (e.g., nitrile rubber) and goggles. Flush immediately with water if contact occurs.
Firefighting: Use alcohol-resistant foam, dry powder, or CO2; avoid water jet (may spread fire).
Storage and Transportation:
Store in a cool, ventilated place, sealed and away from fire sources. Separate from oxidizers, alkali metals, and food chemicals.
Classified as a hazardous chemical (UN number: 1688, Category 3 flammable liquid) during transportation.
Environmental Impact
Biodegradability: Slowly degrades in soil and water, but large spills may contaminate groundwater.
Ecotoxicity: Toxic to fish and aquatic organisms; avoid discharge into natural water bodies.
