Vapour Pressure-Zinc Chloride ZnCl2

Vapour Pressure-Zinc Chloride ZnCl2

Vapour Pressure-Zinc Chloride ZnCl2

(OP)
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

RE: Vapour Pressure-Zinc Chloride ZnCl2

from my personal/desk copy of the CRC Handbook, vintage 1958, vapor pressure of zinc chloride, ZnCl2:

melt point 365 oC
1 mmHg @ 428 oC
10 mmHg @ 508 oC
40 mmHg @ 566 oC
100 mmHg @ 610 oC
400 mmHg @ 689 oC
760 mmHg @ 732 oC

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

RE: Vapour Pressure-Zinc Chloride ZnCl2

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 oC, Boiling Point: 732oC. Mol. Wt.: 136.29.

CAS #: 7646-85-7
