Which institutions or universities can determine vapor-liquid equilibrium data
Thread Content
I’m asking everyone: which institutions or universities can determine vapor-liquid equilibrium data? Urgent! My system is dimethyl carbonate-methyl carbamate-methanol, and it is required to be able to determine the vapor-liquid equilibrium at a pressure of 0.7 MPa and a temperature of around 170 degrees Celsius.

Any ordinary laboratory will do. The prerequisite is the presence of analytical instruments.
Tianjin University can do it. I remember that our research group measured the gas-liquid equilibrium constants for substances like dimethyl percarbonate and diethyl carbonate. Since I didn’t do the experiments myself, I don’t know the specific values. If you need them, you can look up articles on this topic online
China University of Petroleum (East China) can
Go to Zhejiang University; they have previously provided vapor-liquid equilibrium data for low-temperature methanol washing for Dalian University of Technology, so it shouldn’t be difficult to carry out this work for you.
Zhejiang University is fine; we entrusted them to work on a 0.7MPA system
Is it the system mentioned above? How is the accuracy?
May I ask which teacher at Zhejiang University you are contacting, and what are the contact details? Thank you
Can that school conduct negative-pressure gas-liquid equilibrium experiments?
Qingdao University of Science and Technology can also conduct measurements of vapor-liquid equilibrium data, and this can be done under reduced pressure as well. But building a pressure system is not easy! Last edited by u8978 on 2009-2-18 07:47]
Thank you all. After some research, I found that Professor Wang Qi from Zhejiang University and Professor Yun Zhi from Nanjing University of Technology are experts in the determination of vapor-liquid equilibrium data under high pressure, and their instruments are quite precise.
I’m not sure if the company contacted upstairs can handle vapor-liquid equilibrium under negative pressure If you can get in touch, please let me know. I would be very grateful
