| Hazard Information | Back Directory | [General Description]
A clear colorless liquid. Flash point 95°F. Less dense than water and insoluble in water. Vapors heavier than air. | [Reactivity Profile]
METHYLAMYL ACETATE(108-84-9) 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. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids . | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Hazard]
Moderate fire risk. Toxic by inhalation. | [Health Hazard]
Headache, dizziness, nausea, irritation to respiratory passages. Irritates eyes. | [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. | [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, including
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 medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [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. | [Description]
sec-Hexyl acetate is a colorless liquid with amild, pleasant,fruity odor. Molecular weight= 144.24;Specific gravity (H2O:1) = 0.86; Boiling point= 147.2℃;FreezingMelting point= -63.88C; Relative vapor density(air= 1) = 5.0;V aporpressure = 3 mmHg:Flashpoint = 45℃; Autoignition temperature = 266℃. Explosivelimits: LEL= 0.9%; UEL = 5.7%. Hazard Identification(based onNFPA-704MRating System): Health 1,Flammability 2, Reactivity 0. Insoluble in water. | [Chemical Properties]
All isomers of amyl acetate are highly flammable,
colorless to yellow, watery liquids. | [Chemical Properties]
Colorless liquid; mild odor.
Insoluble in water; soluble in alcohol. Combustible. | [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. | [Preparation]
by direct esterification of Methyl-iso-butylcarbinol with Acetic acid or Acetic
anhydride. | [Production Methods]
sec-Hexyl acetate is produced via catalytic reaction of 4-
methyl-2-pentanol and acetic acid.
It also occurs naturally in apples and their leaves. | [Chemical Reactivity]
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | [Environmental Fate]
Chemical/Physical. Slowly hydrolyzes in water forming 4-methyl-2-pentanol and acetic acid. | [storage]
Color Code- _Red: Flammability Hazard: Store ina flammableliquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with hexyl acetate you should be trainedon its proper handling and storage. Before entering confinedspace where this chemical may be present, check to makesure that an explosive concentration does not exist. Store intightly closedcontainers in a cool, well-ventilated area.Metal containers involving the transfer of this chemicalshould be grounded and bonded. Where possible, automati-cally pump liquid from drums or other storage containers toprocess containers. Drums must be equipped with self-clos-ing valves, pressure vacuum bungs, and flame arresters. Useonly nonsparkingtools and equipment, especially whenopening and closing containers of this chemical. Sources ofignition, such as smoking and open flames, are prohibitedwhere this chemical is used, handled, or stored in a mannerthat couldcreate a potential fire or explosion hazard. .Wherever this chemical is used, handled, manufactured, orstored, useexplosion-proof electricalequipmentandfittings. . |
