AMYL ACETATE

CAS NO.: 628-63-7
EC/LIST NO.:

Amyl acetate (pentyl acetate) is an organic compound and an ester with the chemical formula CH3COO[CH2]4CH3 and the molecular weight 130.19 g/mol.
Amyl acetate has a scent similar to bananas and apples.
The compound is the condensation product of acetic acid and 1-pentanol.
However, esters formed from other pentanol isomers (amyl alcohols), or mixtures of pentanols, are often referred to as amyl acetate.

The amyl acetates are made industrially in essentially the same way they are made in a high school or college chemistry laboratory.
Acetic acid (HC2H3O2) is added to amyl alcohol (C5H11OH) with a small amount of concentrated sulfuric acid (H2SO4) as a catalyst.
The specific amyl acetate produced depends on the specific amyl alcohol used in the reaction.
The product is separated from the reaction mixture by boiling the liquid mixture.

Amyl acetate (A-mil AS-uh-tate) is a colorless liquid with a distinctive banana-like flavor and odor.
Three major isomers of amyl acetate exist: normal (n-amyl), secondary (secamyl), and isoamyl (3-methyl-1-butyl) acetate.
Isomers are two or more forms of a chemical compound with the same molecular formula, but different structural formulas and different chemical and physical properties.
As an example, the boiling points of the three isomers of amyl acetate are 149.2°C (300.6°F), 142.0°C (287.6°F), and 140.0°C (284.0°F), respectively.
Although the amyl acetates are probably best known as flavoring agents because of their distinctive banana-like flavor, they all have a number of interesting industrial applications also.

Amyl Acetate, Natural has an odor similar to bananas and apples and this organic compound is often used as a flavoring agent.
Amyl acetate can also be used as a solvent and also as a synthetic intermediate in the preparation of penicillin.
Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use.

Amyl acetate is a straight chain ester.
Amyl acetate is an odorant and its odor threshold has been evaluated by sensory panel methods.
High pressure phase behavior of type I has been reported for its binary mixtures with CO2.
Solubility of these solvent mixtures was observed to increase with the rise in temperature at constant pressure.

Amyl acetate , also known as amyl acetic ester or amyl acetic acid, belongs to the class of organic compounds known as carboxylic acid esters.
These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Pentyl acetate is a banana, ethereal, and fruity tasting compound. Pentyl acetate has been detected, but not quantified in, several different foods, such as sweet bays (Laurus nobilis), sweet cherries (Prunus avium), evergreen blackberries (Rubus laciniatus), papayas (Carica papaya), and asian pears (Pyrus pyrifolia). This could make pentyl acetate a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Pentyl acetate.

Amyl acetate (pentyl acetate) is an organic compound and an ester with the chemical formula CH3COO[CH2]4CH3 and the molecular weight 130.19 g/mol.
Amyl acetate has a scent similar tobananas and apples which is not detectable by all people.
The compound is the condensation product of acetic acid and 1-pentanol.
However, esters formed from other pentanol isomers (amyl alcohols), or mixtures of pentanols, are often referred to as amyl acetate.

Amyl Acetate and Isoamyl Acetate are solvents used to dissolve other ingredients.
In cosmetics and personal care products, Amyl Acetate is used in nail polish and enamels, nail enamel removers and manicure preparations.

Amyl Acetate and Isoamyl Acetate may be used to dissolve other ingredients.
Amyl Acetate and Isoamyl Acetate are also used as a fragrance ingredients due to their pear- or banana-like aromas.

The n-amyl acetate synthesis from the esterification reaction of acetic acid and n-amyl alcohol in a pilot plant catalytic distillation column with a decanter was evaluated.
A novel catalytic packing, seepage catalytic packing internal (SCPI), is applied in this study.
Catalytic distillation experiments using different feed molar ratios and feed modes at different column pressures were performed to validate an equilibrium stage model developed to investigate the influence of operation parameters on the performance of the catalytic distillation process.
The results from experimental runs and simulations clearly indicate that it is important to the performance of catalytic distillation process to adjust the composition and temperature profiles along the reaction zone.
The studies also showed that the integration of a reactive distillation column with a decanter is considered a potential candidate to produce amyl acetate.
With proper operation parameters (operating pressure of 20–22 kPa and mixed feeding mode) and column configuration (16–18 theoretical stages of reaction zone), the product purity in the bottom stream could be increased to 99.3 wt % and less than 0.2 mg KOH/g acid value, meanwhile the conversion of amyl alcohol could reach more than 95%.
The research achievements can be applied to facilitate industrial application of SCPI and used for prospective optimization studies.

N-amyl acetate appears as a mixture of isomers.
A clear colorless liquid with a banana-like odor.
Flash point varies from 65° F to 95°F.
Less dense (at 7.2 lb / gal) than water and slightly soluble in water.
Hence floats on water.
Vapors heavier than air.
