The vapor pressure of TCP was determined by measuring the loss rate under vacuum conditions at 50 deg C. The mass loss of a four-component aryl phosphate ester additive mixture was also measured. The loss-rate was modeled, and the component vapor pressures were determined by fitting the model to the experimental loss data. The values measured were significantly lower than those obtained through extrapolation of higher-temperature vapor pressure data.
