Abstract : The vapor pressure of liquid pentaborane from 25 to 75 C is described by the equation: log P is e ual to 5.6352-1384/(t +250), where P is the vapor pressure in psia, and t is the temperature in degrees C. From 75 to 125 C, the vapor pressure is described by the equation: low P is equal to 4.4803-730/(t +160). The thermal conductivity of liquid pentaborane from 70 to 105 F is described by the following equation: K is equal to 0.0874-(0.0000684 x t), where K is the thermal conductivity, BTU/hr-sq ft (degrees F/ft), and t is the temperature, degrees F.
