One is released by the koschevnikov gland, near the sting shaft, and consists of more than 40 chemical compounds, including isopentyl acetate (ipa), butyl acetate, 1-hexanol, n-butanol, 1-octanol, hexyl acetate, octyl acetate, n-pentyl acetate and 2-nonanol these chemical compounds have low molecular weights, are highly volatile, and appear to. By causing a reaction between ethanoic acid, more commonly known as acetic acid, and 3-methyl-1-butanol or isopentyl alcohol, the ester isopentyl acetate (3-methyl-1-butyl ethanoate) is produced isopentyl acetate is easily recognizable by the strong, banana, odor.

Isopentyl ethanoate or besides known as banana flavoring the mechanism used here was fischer esterification it is the procedure of organizing an ester by refluxing a carboxylic acid and an intoxicant in the presence of an acerb accelerator.

Sythesizing isopentyl acetate by the fischer esterification the purpose of this experiment was to synthesize isopentyl acetate via an esterification reaction between acetic acid and isopentyl alcohol, using concentrated sulfuric acid as a catalyst. Recitation notes for experiment # 13 preparation of isopentyl acetate (banana oil) have your lab textbook available for quick reference to specific pages, indicated in red. (reagent in excess) (limiting reagent) (theoretical yield) (percent yield) summary in conclusion, experimental general procedures acetic acid and isopentyl alcohol were used to in the synthesis of an ester of isopentyl acetate by way of fisher esterification.

Isopentyl acetate was successfully synthesized using microwave radiations instead of sulfuric acid the acetate was obtained by titration in 65 percent yield upon examination of the ir spectrum, it was found out that the product spectrum had similarities with the reference ir. Why is it easier to remove excess acetic acid from the products than excess isopentyl alcohol it is easier to remove excess acetic acid than excess isopentyl alcohol because of solubility acetic acid is more polar than isopentyl alcohol so it is more prone to dissolve in the aqueous layer as opposed to the organic layer.

Synthesis of an ester, isopentyl acetate isolation of isopentyl acetate from the excess acetic acid purification of the isopentyl acetate by distillation moles of isopentyl alcohol = 39973g/(88g/mol) = 0045mol of isopentyl alcohol because of 1 to 1 mole ratio of isopentyl alcohol and isopentyl. Structure, properties, spectra, suppliers and links for: pentyl acetate, 628-63-7. Purpose synthesis isopentyl acetate (banana oil) from isopentyl alcohol, acetic acid, sulfuric acid, and heat with purity of which will give us highest yield and purity of product about 12% eqv to isopentyl alcohol because it is not going to be used up in the experiment - only need a small amount to lower activation.

For example, low temperatures (~10 °c) favor the synthesis of fruit esters, such as isoamyl, isobutyl, and hexyl acetates, whereas higher temperatures (15-20 °c) promote the production of higher-molecular-weight esters, such as ethyl octanoate, ethyl decanoate, and phenethyl acetate (killian and ough, 1979) higher temperatures also tend to.
