Densities, isobaric thermal expansion coefficients and isothermal compressibilities of linear alkylbenzene

Abstract

Abstract. We report the measurements of the densities of linear alkylbenzene at three temperatures over 4 to 23• C with pressures up to 10 MPa. The measurements have been analysed to yield the isobaric thermal expansion coefficients and, so far for the first time, isothermal compressibilities of linear alkylbenzene. Relevance of results for current generation (i.e. Daya Bay) and next generation (i.e. JUNO) large liquid scintillator neutrino detectors are discussed.PACS numbers: 65.20.Jk, 29.40.Mc, 14.60.Pq Densities, isobaric thermal expansion coefficients and isothermal compressibilities of linear alkylbenzene2
