Where can water activity data of salt solutions at higher temperature (75 Centigrade) be found?

10 October 2017 1 4K Report

I am in need of water activity data (aw) of salt solutions at high temperature (between 70 and 80 degrees C) for NaCl, NaI, NaNO3, Na2SO4, KSCN, and KCl. A starting point for my search would be very helpful.

You may want to derive the required activity coefficient data from vapour pressure data for the considered salt aqueous solutions by the mentioned temperature interval (70―80 ºC) ― as discussed elsewhere at RG: https://www.researchgate.net/post/Can_I_find_the_activity_coefficient_of_a_solute_from_the_vapor_pressure_data_Txy_of_the_mixture
