where subscript 2 stands for the solute and 1 for the solvent: x2 is the mole fraction of the solute in the solvent; f2 is the fugacity of the solute in the gas phase. Henry’s constants for hydrogen in the three aromatic compounds were evaluated by extrapolating a plot of fH,lxHl to xH = 0. The fugacity of hydrogen in the gas phase, fw was calculated from the Soave-Redlich-Kwong equation of state (4). Figure 2 shows the plot of Henry’s constants vs. temperature. The values of

these constants are tabulated in Table IV. For comparison purposes, the Henry’s constant of hydrogen in 9,lOdihydrophenanthrene, calculated from data of Sebastian et al. (3),are also shown in Figure 2.
Acknowledgment Thanks are due Mr. Tor Kragas for zone purifying the polyaromatic compounds.

Density and Surface Tension of 83 Organic Liquids GBbor Karosi and E. sz. Kovlts” Laboratoire de Chimie Technique de I’Ecole Polytechnique F6d6rale de Lausanne, 10 15 Lausanne, Swkzerland
Densltles and surface tenslons of organlc llqulds of known purlty were measured In the temperature range of 20-80 OC. In many cases llterature data from apparently reliable sources conflicted with each other. Our measurements were conducted wlth the alm of maklng a choice. Also Included are data of a few compounds of hlgher molecular welght measured In a broader temperature range. In the present paper densities and surface tensions are given for 75 pure liquids and 8 purified polymers. The surface tensions of about half of the substances have been reported in the excellent critical review of Jasper ( I ) , and his recommended values are compared with our data in Table 11. In most cases the surface tensions agree within the experimental error, but, where significant deviations were found, the substances were reexamined with special care in order to obtain the most reliable values.
1. Compounds In Table Iinformation is given about origins, methods of purification, purities, refractive indexes, and melting points of the compounds examined. Compounds 16-24 are branched hydrocarbons of the general structures A1 and A2 with following formulas:
A1 A1-C,, R = hexyl AI-C,,, R = decyl AL-C,,, R = tetradecyl AI-C,,, R = octadecyl
A2 A2-C, ,,R = hendecyl A2-C,,, R = tridecyl A2-C,,, R = pentadecyl A2-C,,, R = octadecyl A2-C2,, R = docosy1
Squalane (15) is a mixture of the diastereomers of 2,6,10,15,19,23-hexamethyttetracosane. Compounds 69-76 are poly(ethy1ene glycols) (PEGS) and their methoxylated derivatives (PEGM) with nominal molecular masses of 600, 1000, 2000, and 20000. The average molecular masses of the HO(CH,CH,O),H
H,CO(CH,CH,O),CH,
PEGM
PEG
PEGSdetermined by the method of ref 2 are as follows: PEG 600, 6.10 X lo2: PEG-1000, 1.13 X lo3: PEG2000, 2.15 X lo3: PEG20000, 1.71 X 10‘. The derivatives PEGM were prepared from the PEGS: consequently, their average molecular masses are MW(PEGM) = MW(PEG) 24. Under the synthetic conditions no degradation is to be expected. 1. I . Or@n. In the third column of Table I,the origin of the compounds is indicated by using the following abbreviations: FI, Fluka AG, Buchs, Switzerland: EGA, EGA-Chemie, Steinheim, Germany: Sh, Shell Research Laboratories, Amsterdam, Holland: Me, Merck AG, Darmstadt, Germany; Syl, Synthetized in our laboratory, see ref 3: Sy2, Synthetized in our laboratory, see ref 2. 1.2. Purlflcatlon. Commercially available research-grade compounds have been further purified. The method of purlfication is indicated in the fourth column of Table I by using the following abbreviations. Di: Distillation of the product in a Vigreux column discarding a forerun and a residue, each representing 25 % of the distilled material. This operation was capable of removing other members of homologous series to less than 0.2%. Di/Na: Distilled over sodium. Di/Hg: Distilled over mercury. Cr: Recrystallization from diethyl ether (DE), propanol (Pr), cyclohexane (CH), ethanol (E), or nhexane (H) or from a mixture of them. For example, the symbol “Di: 3XCr(E/DE)” means that the middle fraction of the distillation was recrystallized three times from a mixture of ethanol and diethyl ether. Fi: Filtration on a silica gel column (Merck: Kieselgel 60)
