Aspen property estimation for phosphorus trichloride properties: warning and no results
Thread Content
Version: Aspen Plus V9. Substance to be estimated: Phosphorus trichloride, PCl3. The process is as follows: 1. Create a new non-database version, and enter the Component ID. 2. Enter the molecular structure. 3. Enter the standard boiling point. 4. Select Estimation as the RUN Mode to estimate all parameters. 5. Run the simulation; a warning appears. 6. Check the results – no data is available. Waiting for results. . . . . .
PCES-1 already contains some results; by providing only the molecular weight and TB, it can only estimate such limited physical properties. Moreover, PCL3 is supposed to be a very common substance – why isn’t it in your database? I do have it; mine is only version 8.4

Since I encountered an error when estimating other compounds with phosphorus-chlorine bonds, I tried to use phosphorus trichloride, which is already available in the database, to conduct the estimation in order to find out where the problem lay CH3PCl2 – this substance is not available in the database. Could you give an estimate? Thank you!

In Xiong Jieming’s book on P30 it is stated: \"If estimations have already been performed earlier, the physical property parameters for the pure components are available. If estimation needs to be done again, the original parameters should, in principle, be deleted; otherwise the system will treat them as user-input parameters and will not carry out further estimation.\"”
