Aqueous sodium hydroxide (20.4 wt% or 5.01 M) at 90 °C in a 2-Liter reactor. Typically, VX was feed into the sodium hydroxide solution at 11.35 g/min. Stirring with a four-bladed 2” Rushton turbine radial flow impeller was maintained at 950 rpm, and a nitrogen purge was used to eliminate CO2 from the reactor during the reactions.

Cp° = A + B*t + C*t2 + D*t3 + E/t2
H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G
Cp = heat capacity (J/mol*K)
H° = standard enthalpy (kJ/mol)
S° = standard entropy (J/mol*K)
t = temperature (K) / 1000.
