Dear fellow sailors, I used ASPEN to calculate whether N,N-dimethyl-1,3-propanediamine and water are azeotropic. The calculation results indicated that they are not azeotropic, but our technical staff say that they are. I would like to ask everyone for their opinion – is this mixture azeotropic? Thank you

There is no azeotrope at a negative pressure of -50 kPa. Those who have the information, please share it.

It seems to have been resolved; why is there still a problem? I’ve sent you screenshots
