WebApr 8, 2024 · Ethyl methanoate boils at 54.3C but methyl ethanoate boils at 57C. These two organic compounds have the same molecular mass. In fact, they're just made by swapping who is the acid and who is the alcohol. Thus I would suspect them to have the exact same boiling point. Yet one is higher than the other by an appreciable margin.

WebJan 23, 2024 · To make a small ester like ethyl ethanoate, you can gently heat a mixture of ethanoic acid and ethanol in the presence of concentrated sulfuric acid, and distil off the ester as soon as it is formed. This prevents the reverse reaction happening. It works well because the ester has the lowest boiling point of anything present.
