1-Pentanol Chemical Properties,Uses,Production
Description
1-Pentanol is a monohydroxy alcohol. It is a colorless liquid with a characteristic odor. Its combustion properties have been studied as it shows promising features to be an alternative to gasoline and diesel fuels. The conversion of 1-pentanol to di-n-pentyl ether (DNPE) in liquid phase at 423K in a batch reactor using ion exchange resins as catalysts.
Chemical Properties
1-Pentanol is a clear, colorless liquid at ambient temperatures.The air odor detection level (lowest perceptible level) was reported as 10 ppm for 1-pentanol .
Occurrence
Reported found in banana, sweet cherry, cranberry, bourbon, vanilla, rice bran and Brazil nut.
Uses
Raw material for pharmaceutical preparations;organic synthesis solvent.
1-Pentanol is used as a key starting material in the production of dichloro-acetic acid pentyl ester, 2-methyltetrahydrofuran, di-n-penyl ether (DNPE), pentyl butyrate and amyl acetate. As a solvent, it is used for coating CDs and DVDs. It has been considered to be a replacement for gasoline and diesel fuels due to its combustion properties. Further, it is used as a reagent to prepare derivatives of ferulic acid and caffeic acid, which shows anticancer properties.
Production Methods
1-Pentanol is made primarily by the oxo process, which involves the reaction of butenes with carbon monoxide and hydrogen in the presence of a catalyst, followed by hydrogenation. 1-Pentanol is used as a solvent, as a chemical intermediate for esters, and as a food additive and flavoring substance. The primary routes of industrial exposure are by dermal contact and inhalation.
Definition
ChEBI: An alkyl alcohol that is pentane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It has been isolated from Melicope ptelefolia.
General Description
A colorless liquid with a mild to moderately strong odor. Less dense than water. Flash point 91°F. Boiling point 280°F. Vapors heavier than air. Moderately toxic by ingestion. Vapors may irritate skin and eyes. Used as a solvent and to make other chemicals.
Pentanol is incompatible with strong oxidising agents, alkali metals, alkaline earth metals, halogens, hydrogen trisulphide, acids, acetaldehyde, acid anhydrides, acid chlorides, lithium aluminium hydride, isocyanates, dialkylmagnesiums, n-halomides, ethylene oxide, hypochlorous acid, hydrogen peroxide and sulphuric acid, nitrogen tetraoxide, nitryl hypochlorite, permonosulphuric acid, and tri-isobutyl aluminium.
Air & Water Reactions
Highly flammable. Soluble in water.
Reactivity Profile
Moderately toxic, flammable if exposed to powerful oxidizers. Incompatible with oxidizing materials, hydrogen trisulfide [Sax, 9th ed., 1996, p. 224].
Hazard
Lower explosive level in air 1.2% by volume. Moderate fire risk.
Health Hazard
Irritation of skin, eyes, and respiratory tract; headache and vertigo; dyspnea and cough; nausea, vomiting, and diarrhea. Double vision, deafness, delirium, and occasionally fatal poisoning, preceded by severe nervous symptoms, have been reported. Coma, glycosuria, and methemoglobinemia can occur.
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.
Safety Profile
Moderately toxic by ingestion and skin contact. An eye and upper respiratory irritant by inhalation. A severe skin and eye irritant. Ingestion can cause headache, nausea, vomiting, delirium, and methemoglobin formation. Mutation data reported. Extremely flammable if exposed to heat, flame, or powerful oxiduers. Moderately explosive when exposed to flame. Incompatible with oxidzing materials, hydrogen trisulfide. To fight fire, use alcohol foam, dry chemical.
Potential Exposure
(n-isomer); Suspected reprotoxic hazard, Primary irritant (w/o allergic reaction), (iso-, primary): Possible risk of forming tumors, Primary irritant (w/o allergic reaction), (sec-, active primary-, and other isomers) Primary irritant (w/o allergic reaction). Used as a solvent in organic synthesis and synthetic flavoring, pharmaceuticals, corrosion inhibitors; making plastics and other chemicals; as a flotation agent. The (n-isomer) is used in preparation of oil additives, plasticizers, synthetic lubricants, and as a solvent.
Shipping
UN2811 Pentanols, Hazard Class: 3; Labels: 3- Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.
Purification Methods
Dry 1-pentanol with anhydrous K2CO3 or CaSO4, filter and fractionally distil it. It has also been treated with 1-2% of sodium and heated at reflux for 15hours to remove water and chlorides. Traces of water can be removed from the near-dry alcohol by refluxing it with a small amount of sodium in the presence of 2-3% n-amyl phthalate or succinate followed by distillation (see ethanol). Small amounts of amyl alcohol have been purified by esterifying with p-hydroxybenzoic acid, recrystallising the ester from CS2, saponifying with ethanolic-KOH, drying with CaSO4 and fractionally distilling [Olivier Recl Trav Chim Pays-Bas 55 1027 1936]. [Beilstein 1 IV 1640.]
Incompatibilities
Forms an explosive mixture with air. Contact with strong oxidizers and hydrogen trisulfide may cause fire and explosions. Incompatible with strong acids. Violent reaction with alkaline earth metals forming hydrogen, a flammable gas.
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
