Thermal Conductivity of caustic Solution

[khanvessel]

Hi

Does anyone know the thermal conductivity of 50% caustic solution (Aqueous)

Thanks

See section 3 of "The Equations for Thermophysical Properties of Aqueous Solutions of Sodium Hydroxide" by Alexey A. Alexandrov:

http://www.iapws.jp/Proceedings/Symposium02/086Alexandrov.pdf

The thermal conductivity is given in equation form, as a function of concentration & temperature. Note: the molality of a 50 wt% NaOH solution is 12.5.

Refer to Graph 8 "Thermal Conductivity of Aqueous Caustic Soda Solutions" on Page 36 of the OxyChem Caustic Soda Handbook. You can download a copy from the following web address
