The　density　and　viscosity　of　the　cyclopropyl　methyl　ketone　(CPMK)　+　2-acetylbutyrolactone　(ABL)　and　CPMK　+　5-chloro-2-pentanone　(CPE)　binary　mixtures　were　measured　at　the　temperature　range　of　303.15　to　333.15　K　at　atmospheric　pressure　(about　101.325　±　0.3　kPa).　The　excess　molar　volume　and　viscosity　deviation　were　calculated　based　on　the　experimental　data　of　density　and　viscosity,　and　they　could　be　accurately　described　by　the　Redlich-Kister　equation.　In　addition,　the　vapor-liquid　equilibrium　(VLE)　data　for　the　CPMK-ABL　binary　system　were　measured　at　atmospheric　pressure.　It　was　shown　that　there　is　no　azeotrope　in　this　binary　mixture.　The　VLE　data　were　correlated　with　NRTL,　Wilson,　and　UNIQUAC　models　and　the　interaction　parameters　obtained　were　reported.　The　prediction　accuracies　of　these　models　were　about　the　same.　©　2017　American　Chemical　Society.
