Hi,

Does anybody have any suggestion witch chemical solution would be a good substitute for MIPA (1-Amino-2-propanol). I am looking for very polar solution with high boiling point (more than 240°C). Any suggestion what can I use? 

Tnx

What about glycol ether

Sulphuric acid meets the criteria you gave but it may be unsuitable.
If you tell us what you are seeking to do we might be better able to help.

I am looking for a solution that would replace the features of MIPA. I am using MIPA for better milling but problem is that I heat it up later (together with material) and the MIPA decompose. Now I am looking for very polar solution with high boiling point which will not decomposed. 

tnx 

DIPA or TIPA?
