What should I do if I can’t find the required component in the Aspen component input?
Thread Content
My Aspen version is V7.3, and I want to enter 3-hydroxypropanal (C3H6O2). Even after loading all the databases and performing searches, it still can’t be found. Searching for the CAS number 2134-29—4 also yields no results. What should I do?
If entering the molecular formula in the search function doesn’t work, one has to draw it manually, creating the structure and defining it on their own
If you don’t want to draw the structure yourself, you can also use Chemspider to search by CAS number, download the molecular structure file *.mol, and import it into ASPEN.
Use custom components ~ then estimate physical properties~
