| | 1-METHYLBUTYL ACETATE Usage And Synthesis |
| Chemical Properties | 2-Pentyl acetate has an herbaceous odor. | | Chemical Properties | All isomers of amyl acetate are highly flammable,
colorless to yellow, watery liquids. | | Physical properties | Clear, colorless liquid with a fruity odor. Odor threshold concentration is 2.0 ppb (quoted, Amoore
and Hautala, 1983). | | Occurrence | Reportedly present in over 50 products including apple, apple juice, grape (muscat), apricot, banana, cherry,
guava, melon, peach, blackberry, pear, strawberry, nectarine, potato, tomato, cocoa liquor, and vinegar. | | Uses | Manufacture of lacquers, artificial
leather, photographic film, artificial glass, celluloid,
artificial silk, and furniture polis | | Uses | Solvent for nitrocellulose and ethyl cellulose,
cements, coated paper, lacquers, leather finishes,
nail enamels, plastic wood, textile sizing, and print-
ing compounds. | | Preparation | Prepared from alcohols using acetic acid as an acetylating agent and clays as catalysts (patented process). | | Definition | ChEBI: 2-Pentanol acetate is a carboxylic ester. | | Aroma threshold values | Detection at 0.001 to 0.002 ppm (water) | | General Description | Colorless to yellow watery liquid with a weak odor of bananas. Floats on water. Produces irritating vapor. | | Air & Water Reactions | Highly flammable. Slightly water soluble. | | Reactivity Profile | 1-METHYLBUTYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. 1-METHYLBUTYL ACETATE is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids . | | Hazard | Flammable, moderate fire risk. Toxic.
Upper respiratory tract irritant. | | Health Hazard | INHALATION AND INGESTION: Irritates the mucous membrane, depresses the central nervous system, and is a narcotic. Damage to kidney, liver, and lung can occur. Ingestion may irritate gastro-intestinal tract. EYES: Irritation. Skin: Irritation. | | Safety Profile | Mildly toxic by
inhalation. Human systemic effects by inhalation: conjunctiva irritation. Dangerous
fire hazard when exposed to heat or flame;
can react with oxidizing materials.
Moderately explosive in the form of vapor
when exposed to heat or flame. To fight
fire, use alcohol foam, dry chemical. When
heated to decomposition it emits acrid
smoke and irritating fumes. | | Potential Exposure | (n-isomer): Primary irritant (w/o allergic
reaction), (sec-isomer) Human Data. Amyl acetates are
used as industrial solvents and in the manufacturing and
dry-cleaning industry; making artificial fruit-flavoring
agents; cements, coated papers, lacquers; in medications
as an inflammatory agent; pet repellents, insecticides and
miticide. Many other uses. | | Environmental fate | Chemical/Physical. Slowly hydrolyzes in water forming acetic acid and 2-pentanol. | | Shipping | UN1993 Flammable liquids, n.o.s., Hazard
Class: 3; Labels: 3-Flammable liquid, Technical Name
Required. | | Incompatibilities | Vapors may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides, nitrates. May soften certain plastics. | | 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.
In accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers. Must be
disposed properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office. |
