The dark yellow liquid boils under atmospheric pressure at 138° C. Atthe 
boilingpoint z~ has a value of about: 29.0 Erg. The specific weight at 0° C. 
is 1.7094; at 138°.1 C.: 1.4920 (THORPE). 
The temperature-coefficient of » is originally, up to 50°C. about: 2,24 Erg; 
afterwards it diminishes to about 1.79 Erg. per degree.

| The chloride boils under a pressure of 749 mm. at 75° C. Even at —75° C. 
it is again a thin liquid, but solidifies, according to TIMMERMANS, at —90° C. 
At the boilingpoint 7» has the value: 21.9 Erg. The specific gravity at 16°.4 C. 
is: 1,582; at 46.2 C.: 1,527; the critical temperature is: 290° C. (Ramsay 
and SHIELDs). The temperature-coefficient of « is relatively small: about 1,61 
Erg per degree, as a mean value.
