I am currently working on modelling the temperature runaway in a CSTR with the catalytic decomposition of hydrogen peroxide using potassium iodide as the catalyst. Unreacted hydrogen peroxide is one of the compounds leaving the CSTR and some of it will be in the vapor phase while the rest remains a liquid. In the attempt to find a model that will begin to describe the data we obtained, Dalton's law is used along with the definition of partial pressure to turn the proportion of molar flows into a proportion of the vapor pressure of a product to the total pressure of the mixture.

My problem is that I am unable to find a free resource that has antoine coefficients for hydrogen peroxide available, and in my digging I found a few sources that mentioned the difficulty of measuring properties of hydrogen peroxide due to the decomposition occurring at elevated temperatures.

So what I am looking for is any resource that has another way to model the vapor pressure of hydrogen peroxide as a function of temperature or even a different method of estimating molar flow rates in the vapor or liquid streams of a non-isothermal CSTR with hydrogen peroxide, and water existing in both the liquid and vapor phases, while the oxygen produced is assumed to be solely a gaseous product. The temperature range we are working in is 0 to 100 degrees C.
