Bourdon gauge. Each cylinder was about 100 cm capacity and contained moles of CH3SiH3 varying from 0.029 to 0.197, and of CH3SiCl3 from 0.176 to 0.0421. [Pg.229]

The pressures were registered as psia, but I give the equivalents in atm. It is pointless to detail the mode of calculation of the solubility data suffice it to state that the total pressure was observed, and the partial pressure of methyltrichlorosilane was calculated from Raoult s law and subtracted from the total pressure to give the partial pressure of methylsilane. I have translated their data and registered these as crosses near my R-line in Fig. 143. [Pg.229]

In connection with the preparation of diborane, the solubility pattern for ethane type solvents was needed. Elliott et al expressed their results for [Pg.229]

McCarty and Guyon (1954) expressed the solubility in n-pentane as mole percent, i.e., the mole fraction form, and declared that Raoult s law applies very well. In Fig. 144,1 have plotted the Nb2H6 vs Pb2H6 and Xb2H6 vs Pb2H6 values, and I [Pg.229]

Two further examples of the usefulness of the R-line diagram in the estimation of Na or Xa values in difficult systems are afforded by the following papers. Pearson and Robinson (1932) found a molecular weight of 103.0 for carbonyl selenide (bp —22.9°C) from the gas density at 0 C, whereas its actual molecular weight is 107.2. The discrepancy was attributed to the presence of either carbon monoxide or carbon dioxide, which were stated to be appreciably soluble in the liquid. Under the conditions stated, Xccb would not be more than 0.05, and xco not more than 0.01, The solubility pattern of COSe itself can be approximately assessed by reference to Fig. 140. The R-line values for COSe at 0°C may be assessed at Ncose = 0-41, cose = 0.7 for 1 atm, based on the vapor-pressure data. [Pg.230]
