The critical temperatures of seven isomeric alcohols have been measured using the modified sealed tube method of Mogollon. The ampoule used in the Mogollon method was modified to allow easier handling and reproducible results to be obtained. The addition of an Apple IIe microcomputer to the apparatus made possible the recording of the temperature history of the fluid and the monitoring of successive meniscus disappearances and appearances with time. The critical temperatures were obtained by averaging the temperatures of meniscus disappearance and reappearance. The fill densities of the ampoules were approximately equal to the critical densities.
