✦ Synopsis

The apparent molar volumes and molar isentropic compressibilities of pyrrolidin-2-one (PY) with Triton X-45 (TX-45), Triton X-114 (TX-114), Triton X-100 (TX-100), Triton X-405 (TX-405) have been determined at 303.15 K. Excess molar volume V E is negative throughout the composition range and follows the order TX-45 N TX-114 N TX-100 N TX-405. Molar isentropic compressibility K S and its excess values K S E have been obtained by combining the ultrasonic velocity and excess volume data. The deviations in K S E are negative for TX-45, TX-114 and TX-100 and positive for TX-405 and vary in the order TX 405 N TX 100 N TX 114 N TX 45. The results are compared and discussed to gain insight into the interactions between tritons and pyrrolidin-2-one.
