Butyl acetate is a reactive solvent that has been used in wastewater treatment. It has also been proposed as an analytical method for the determination of the concentration of butyl ester in mixtures. In this technique, a constant pressure is maintained until the butyl ester is released from the sample matrix and enters into a gas phase. The gas phase is then drawn into a solid-phase microextraction (SPME) fiber and analyzed by gas chromatography/mass spectrometry. Butyl acetate has limited solubility in water, which limits its practical use as a solvent. However, it can be mixed with other solvents such as ethanoate or n-butyl acetate to produce solutions that are more easily soluble in water. The structural analysis of butyl acetate was carried out using infrared spectroscopy and nuclear magnetic resonance (NMR).
