Abstract:

It is important to note that hydrocarbon solvents, in spite of their complex composition, are regarded as substances and there fore have one vapor pressure value, just as they have ore flash point value. The objective of this work was to develop arid validate a calculation tool, applicable for the determination of the vapor pressure of hydrocarbon solvents based on readily available physic-chemical properties of the substances. At vapor pressures below 0.1 kPa, many of the measurement techniques, inch as ASTM D323 [3], are not applicable, for suitable methods, sample preparation and handling, and actual measurement are extremely time-consuming hence, in practice, such methods cannot be applied routinely.
