Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH 3 CH 2 CH 2 COOCH 2 CH 3.It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple.n addition, ethyl butyrate is often also added to orange juice, as most associate its odor with that of fresh orange juice. Ethyl butyrate is one of the most common chemicals used in flavors and fragrances.
Therefore, the molar mass of ethyl group is higher than that of the methyl group. â¢ Ethyl is derived from the alkane ethane and methyl is derived from the alkane methane. â¢ In 1 H NMR spectroscopy, coupling due to a methyl group gives a quartet, whereas coupling due to an ethyl group gives a quartet and a triplet.
