Hazard Information

General Description
A clear colorless liquid with a sharp musty odor like rubbing alcohol. Flash point 53-77°F. Autoignites at 700°F. Vapors are heavier than air and mildly irritate the eyes, nose, and throat. Density approximately 6.5 lb/gal. Used in making cosmetics, skin and hair preparations, pharmaceuticals, perfumes, lacquer formulations, dye solutions, antifreezes, rubbing alcohols, soaps, window cleaners, acetone and other chemicals and products.
Reactivity Profile
N-PROPANOL(71-23-8) reacts with alkali metal, nitrides and strong reducing agents to give flammable and/or toxic gases. Reacts with oxoacids and carboxylic acids to form esters plus water. Converted by oxidizing agents to propanal or propionic acid. May initiate the polymerization of isocyanates and epoxides. Incompatible with strong oxidizing agents .
Air & Water Reactions
Highly flammable. Water soluble.
Hazard
Flammable, dangerous fire risk. Explosive limits in air 2–13%. Toxic by skin absorption. Eye and upper respiratory tract irritant. Questionable carcinogen.
Health Hazard
Contact with eyes is extremely irritating and may cause burns. Vapors irritate nose and throat. In high concentrations, may cause nausea, dizziness, headache, and stupor.
Potential Exposure
n-Propyl alcohol is used as as solvent in lacquers, dopes; to make cosmetics; dental lotions; clea- ners, polishes, and pharmaceuticals; as a surgical antiseptic. It is a solvent for vegetable oils, natural gums and resins; rosin, shellac, certain synthetic resins; ethylcellulose, and butyral; as a degreasing agent; as a chemical intermediate.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ- ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi- cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
Shipping
UN1274, n-Propanol, Hazard Class: 3; Labels: 3-Flammable liquid.
Incompatibilities
Vapors may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, perox- ides, permanganates, perchlorates, chlorine, bromine, fluo- rine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. n-Propanol reacts with alkali metal, nitrides and strong reducing agents to give flammable and/ or toxic gases. Reacts with oxoacids and carboxylic acids to form esters plus water. Converted by oxidizing agents to propanal or propionic acid. May initiate the polymerization of isocyanates and epoxides
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinera- tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.

Questions And Answer

Production
  • Isolation from fusel oil
  • Hydroformylation of ethylene (→Propanal), is the primary commercial source of 1-propanol.
  • Liquid-phase catalytic oxidation of propane
  • Propylene being with using zinc oxide/tungsten oxide and lithium hydride as catalysts undergoing at 20.3~25.3MPa and 130~290°C
  • Hydrolysis of halogenated hydrocarbons in alkaline solutions

description
1-propanol is the compound with the hydrogen atom in the propane molecules being replaced by hydroxyl group. Because the hydroxyl group can substitute the hydrogen atoms contained in the carbons in the two terminals of carbon chain or middle carbon, thus generating two isomers, n-propyl alcohol and isopropyl alcohol.
The chemical property of the 1-propanol is similar to that of ethanol. It is the byproduct during the process of the methanol synthesis from carbon monoxide and hydrogen. At room temperature and normal pressure, it appears as colorless transparent liquid with fragrance odor. In industry, it is prepared through the reaction between ethylene, carbon monoxide and hydrogen under high pressure and cobalt catalysis; alternatively through the hydration of propylene under the action of sulfate or through the catalytic hydrogenation of acetone. It is commonly used as a solvent with irritating effect on the eyes and mucosa. Inhalation of propyl alcohol steam can lead to dizziness, headache and vomiting, etc.
Introduction
1Propanol is colorless transparent liquid, with ethanol-like smell, combustible. Soluble in acetone and benzene, miscible with a variety of common organic solvents (e.g., ethers, esters, acids, ketones, and other alcohols). It occurs in nature in crude fusel oils and as fermentation and decomposition products of various vegetables, used mainly as solvent. Azeotropics are formed with a variety of compounds, including aromatics, esters, amines, and ketones (See table below). When the product is oxidized, it can produce propionaldehyde and propionic acid, depending on the reaction conditions and the catalyst; it can form an ester with acid; it can form sodium alkoxide with active metal and be used as organic synthesis catalyst.

Uses
The propanols are used mainly as solvents for coatings; in antifreeze compositions and household and personal products; and as chemical intermediates for the production of esters, amines, and other organic derivatives. As a solvent, 1-propanol is used principally in printing inks, paint, cosmetics, pesticides, and insecticides.
1-Propanol is used commercially to produce glycol ethers. These are characterized by dual functionality, which imparts high solvency, chemical stability, and water compatibility.
