MEASUREMENT OF THE DENSITY OF "SANTOWAX R," PARA-, META-, AND ORTHO- TERPHENYL, DIPHENYL AND DOWTHERM A
The densities of Santowax R, para-, meth-, and ortho-terphenyl, diphenyl, and Dowtherm A were measured as a function of temperature from the melting point to just above the normal boiling point. The probable accuracy ot the results is estimated as plus or minus 1/4%. Comparison with other published data, where available, shows no major discrepancies, agreement on the whole being within plus or minus 1/2%. Because of the variation in composition of Santowax R, the density values obtained can, strictly, only refer to the particular batch or Santowax R from which the sample was taken, however, the densities of the individual isomers are sufficiently close for quite wide variations in composition not to alter the density by more than about plus or minus 1% from the values obtained. The effect or polyphenyls higher than terphenyl in the sample used was to raise the density by about 1/2% above the value expected had these higher polyphenyls been absent. (auth)
