Rajkumar Dewani

Hi Wei, I have added an application note as attachment related to your question. It will hopefully help you with your problem.

Tomasz Kargul

Water begins to evaporate at 100 C and C2H6O2 at about 200, which is why you see a two-stage weight loss.

Wei Xian Hong

Thanks all. Because I was referring the boiling point of a single mixture based on ASHRAE results. I had the same idea when I got similar results for all samples.

Narendra Yadav

Thermal Stability of both the components is different as shown in TGA curve. First stage is refereed to dehydration where water evaporates nearly 100-120 degree Celsius. The weight loss in second stage is attributed to degradation of EG by escaping of volatile components like CO2, H2O, etc.,
