Ester (IUPAC name) 3-methylbutyl ethanoate (isoamyl acetate) ethyl butanoate (ethyl butyrate) pentyl butanoate (pentyl butyrate) octyl ethanoate (octyl acetate) R Formula OH carboxylic acid CH3COOCH₂CH₂CH(CH3)2 carboxylic acid butyric acid acetic acid CH3CH₂CH₂COOCH₂CH3 CH3(CH₂)2COOCH₂(CH₂)3CH3 CH3COOCH₂(CH₂)<CH₂ + R-OH alcohol Boiling point (°C) 142 limiting reagent carboxylic acid alcohol 120 cat. H₂SO4 180 211 In this experiment you will synthesize the ester of your choice from the table above. A general description of the experiment is given. Before coming to the laboratory, calculate the masses of your chosen reagents (alcohol and carboxylic acid). You will be asked to show your calculations to your laboratory instructor for approval. The following example will show you how to approach the problem. Assume that the ester of your choice is hexyl propionate (hexyl propanoate). The alkyl group in the name, hexyl in this case, indicates the alcohol (1-hexanol) from which the ester is made. The second word in the name, propionate (propanoate), indicates the acid used; in this case propionic (propanoic) acid. Knowing the reactants, the alcohol and the carboxylic acid, use the molar masses from the table of reagents in the manual to calculate the masses required Far R Odour ester banana pineapple apricot orange 1.
