Methyl hexanoate, which was found to be the simplest methyl ester to present a strong cool flame behavior, is expected to be one of the main components of biodiesels. Details of the experimental speeds of sound in methyl hexanoate have never been investigated up to now. Therefore, the speed of sound in liquid methyl hexanoate was measured by the Brillouin light scattering method in the temperature range of 297.83-588.07 K and at pressures of up to 10 MPa. The relative uncertainty of the speed of sound experimental system is estimated to be less than 0.43%, and when considering the impurity of the sample, the relative uncertainty is 0.47%. The variation of the speed of sound with the temperature and pressure was analyzed. Besides, the correlation for the speed of sound as a function of temperature and pressure is presented based on the experimental data. The absolute average of relative deviation (AARD) between the experimental data and the calculated results is 0.44%.
