Temperature of attainable superheating of some commercial petroleum products

Measurements of the temperature of attainable superheating of A-76L and AI- 93 motor gasolines; L-0.5-40, L-0.2-40, and Z-0.5-35 diesel oils; TS-1 and RT jet propellants; and T-1500 transformer oil are performed by the method of pulsed heating of a wire probe placed into the liquid under study. The r ate of increase of the probe temperature is 10(5)-10(7) K/s. The pressure v aries from atmospheric to near-critical. The temperature of attainable supe rheating of rocket propellants is also calculated by the theory of homogene ous nucleation. A conclusion is made that, if the thermal properties of a c oncrete batch of petroleum products are known, the theory of homogeneous nu cleation provides a fairly accurate estimate of the temperature of attainab le superheating of substances with so complex a composition.
