✦ Synopsis

nitrogen q diethyl ketone g at standard atmospheric pressure pЊ over the temperature Ž . range 373.2 to 423.2 K. The measurements were analysed using pair potential parameters for nitrogen, assuming suitable combining rules for the calculation of cross-terms, and, for diethyl ketone, finding parameters for the Stockmayer potential which fitted the excess enthalpy measurements. These parameters, which are rk s 720 K, s 0.375 nm, and t* s 0.506, yielded values of the second virial coefficient B for diethyl ketone in satisfactory agreement with other work.
