591-87-7 Usage
Chemical Properties
Allyl acetate is a flammable, colorless liquid with an acrid odor.
Uses
Different sources of media describe the Uses of 591-87-7 differently. You can refer to the following data:
1. Ally acetate is used in nonalcoholic beverages at 1 ppm,
ice cream and ices at 2 ppm, candy at 5 ppm, baked goods at
5 ppm, and margarine at 2 ppm.
2. Ally acetate is used in industrial intermediate. Used in synthesis of colophony and bond.
Production Methods
Allyl acetate is produced by the following methods: decarboxylation
of allylmalonic acid with heat, boiling ethyl 4-
chloro-N-valerate in quinoline, and acetoxylation of
propylene.
Allyl acetate is produced primarily for manufacturing allyl
alcohol. It is also used as a synthetic flavoring for
cheese, butter, and fruit.
General Description
A liquid. Insoluble in water and slightly less dense than water. Hence floats on water. Flash point below 75°F. Poisonous by ingestion and moderately toxic by inhalation and skin contact. Irritating to skin and eyes.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
Allyl acetate is an ester. Reacts with acids to liberate heat along with alcohols and acids. Generates heat with strong oxidizing acids. The reaction may be sufficiently exothermic to ignite the reaction products. Also generates heat with basic solutions. Generates flammable hydrogen with alkali metals and hydrides. Emits acrid smoke and irritating fumes when heated to decomposition.
Hazard
Skin and eye irritant; poisonous.
Health Hazard
TOXIC; may be fatal if inhaled, ingested or absorbed through skin. Inhalation or contact with some of these materials will irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
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 and poison 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
Poison by ingestion. Moderately toxic by inhalation and skin contact. A skin and eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes. Dangerous fire hazard. See also ALLYL COMPOUNDS
Potential Exposure
Allyl Acetate is used to control insects in homes and animal shelters, and to treat lice in humans. May be used to enhance taste of dairy products and fruit. Generally speaking, most allyl compounds may be metabolized to allyl alcohol (see A:0540) which is metabolized to acrolein (see A:0380).
Shipping
UN2333 Allyl acetate, Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials
Purification Methods
The ester is freed from peroxides by standing with crystalline ferrous ammonium sulfate, then washed with 5% NaHCO3, followed by saturated CaCl2 solution. Dry it with Na2SO4 and fractionally distil it in an all-glass apparatus. FLAMMABLE LIQUID. [Beilstein 2 H 136, 2 IV 180.]
Incompatibilities
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. Incompatible with strong acids (liberates heat), nitrates, strong alkalis (liberates heat). Contact with alkali metals and strong reducing agents such as hydrides evolves highly flammable hydrogen gas. Attacks some plastics, coatings, and rubber. Flow or agitation of substance may generate electrostatic charges due to low conductivity; ground all equipment containing this material
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.
Check Digit Verification of cas no
The CAS Registry Mumber 591-87-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 591-87:
(5*5)+(4*9)+(3*1)+(2*8)+(1*7)=87
87 % 10 = 7
So 591-87-7 is a valid CAS Registry Number.

Effect of palladium and copper content of zeolite catalysts on the kinetic parameters of the oxidative acetylation of propylene
Kharlamov,Pogorelov,Panov,Yanchevskaya,Minachev
, p. 2424 - 2429 (1989)
1. Using the methods of mathematical planning of an experiment, a kinetic model has been obtained for the oxidative acetylation of propylene to allyl acetate and the effect of the composition of the Pd, Cu/mordenite catalyst on its parameters has been determined. 2. The kinetic parameters (1g k0)0, Q, 1g a0 and E0 correlate strongly and form a gully on the surface of the minimized functional. Regularization of the values of the kinetic parameters was carried out by isolating a subregion of the gully satisfying the Boudart thermodynamic relationships. 3. On varying the Pd and Cu content of the catalyst within the limits 0.1 to 3.0%, the activation energy and the logarithm of the preexponential factor of the rate constant vary over the range 2-11 kcal/mole and 0.255-3.453, respectively.

A second-generation m-phenolsulfonic acid-formaldehyde resin (PAFR II) catalyst was prepared by condensation polymerization of sodium m-phenolsulfonate and paraformaldehyde in an aqueous H2SO4 solution. This reusable, robust acid resin catalyst was improved in both catalytic activity and stability, maintaining the characteristics of the previous generation catalyst (p-phenolsulfonic acid-formaldehyde resin). PAFR II was applied in the batchwise and continuous-flow direct esterification without water removal and provided higher product yields in continuous-flow esterification than any other commercial ion-exchanged acid catalyst tested.
