Estimation of the binary interaction parameter for diazomethane and water
Thread Content
Experts in the group, regarding the molecular structure of diazomethane (C=N+=N-), it’s not possible to estimate the binary interaction parameters between diazomethane and water using ASPEN’s property estimation system. Has anyone encountered a similar problem?
It’s normal; ASPEN uses the UNIFAC group contribution method for estimating the physical properties of substances, and this method relies on parameters such as the interaction forces between these groups and their surface area. If such data is missing, it’s not possible to carry out the calculations.
