Question

Write the chemical equations, using condensed structural formulas, for the esterification reactions of Part B, and give the IUPAC names of the products. Describe the scent of each of the esters that you produced.

1. methanol CH3OH salicylic acid C6H4OHCOOH

2. methanol CH3OH o-anthranilic acid C6H4NH2COOH (2- aminobenzoic acid)

3. ethanol CH3CH2OH butanoic acid CH3CH2CH2COOH

4. 1-pentanol CH3(CH2)4OH butanoic acid CH3CH2CH2COOH

5. 1-pentanol CH3(CH2)4OH ethanoic acid CH3COOH

6. 1-octanol CH3(CH2)7OH ethanoic acid CH3COOH

Answer 1

1.

Methanol + 2-Hydroxybenzoic acid --> Methyl 2-hydroxybenzoate

It smells and tastes like mint

2.

methanol + 2- aminobenzoic acid --> methyl 2-aminobenzoate (Methyl anthranilate)

it has a fruity grape smell; at 25 ppm it has a sweet, fruity, Concord grape-like smell with a musty and berry nuance

3.

ethanol + butanoic acid ----> Ethyl Butanoate

his scent is typically pineapple.

4.

1-pentanol + butanoic acid --->Penthyl butanoate

This ester has a smell reminiscent of pear or apricot

5.

1-pentanol + ethanoic acid ----> Pentyl ethanoate

It has a scent similar to bananas and apples

6.

1-octanol + ethanoic acid ---> octyl ethanoate

It is used in the food and cosmetic industry as the aromatic base product use to recall the scent of oranges
