High pressure thermophysical characteristics of butyl caprate and butyl laurate as fully biorenewable components of biodiesel fuel

•Butyl caprate and butyl laurate were investigated.•Speed of sound was measured at high pressure.•Density-temperature curves of butyl caprate intersect those of butyl laurate.•Different isentropic compressibility of esters can be compensated by temperature.•The isentropic compressibility of butyl la...
