Vapour Pressure-Zinc Chloride ZnCl2 2

[TISM]

I am trying to generate a curve for the vapour pressure of liquid zinc chloride as a function of temperature. If anyone has a reference I would be very greatful. Alternatively if anyone knows the Antoine coefficients for zinc chloride that would help me out.
Thanks in advance,

TISM

from my personal/desk copy of the CRC Handbook, vintage 1958, vapor pressure of zinc chloride, ZnCl[sub]2[/sub]:

melt point 365 [sup]o[/sup]C
1 mmHg @ 428 [sup]o[/sup]C
10 mmHg @ 508 [sup]o[/sup]C
40 mmHg @ 566 [sup]o[/sup]C
100 mmHg @ 610 [sup]o[/sup]C
400 mmHg @ 689 [sup]o[/sup]C
760 mmHg @ 732 [sup]o[/sup]C

A more modern copy of the above reference may give you the coefficients you seek.

 

[25362]

The CRC 1973 edition brings the following:

42, 481, 536, 584, 648, 689 Celsius, for abs. pressures of
1, 5, 20, 60, 200, 400 mm Hg, respectively.

Melting Point: 290 [sup]o[/sup]C, Boiling Point: 732[sup]o[/sup]C. Mol. Wt.: 136.29.
