Wrapper for DIPPR 801 Properties Database?

I wrote the Mathcad wrapper for NIST REFPROP as well as contributing significantly to the Mathcad wrapper for the open-source alternative CoolProp.  Both of these are based on the Helmholtz equations for the fluids, from which all of the thermodynamic properties can be derived.  Still, neither NIST REFPROP nor CoolProp have the materials you mentioned (DMAc and MMA).  If you can find a verified Helmholtz formulation for the two fluids you mentioned, they could be added as a CoolProp fluid.  A brief internet search for any research articles containing Helmholtz formulations for the two fluids you mentioned did not yield results.  Everything I found was a PC-SAFT formulation, which is what I think DIPPR is based on.

DIPPR is not freely available and most of the wrapper codes for Mathcad are open-source.  The Prode Physical Properties (PPP) database allegedly has an interface to DIPPER.  There was a Mathcad add-in for Prode at one time, but those links all appear to be broken.

Maybe someone else knows of a DIPPR interface, but Google AI pointed to Prode.

@CD_9999850 - I was working on CoolProp over the weekend and remembered there is a new PC-SAFT backend that has a number of fluids represented by the PC-SAFT equations of state (EOS).   One of your fluids (MMA; CAS: 25281-48-5) is in there.  The other (N,N-Dimethylacetamide (DMAc); CAS: 127-19-5) is not.  However, I believe the DIPPR database uses PC-SAFT EOS formulations.  If you can find the PC-SAFT EOS parameters (there aren't many; just "m", "sigma", "u", "dipm", "dipnum", and "molemass") for your fluids, they can be added (either temporarily, or permanently with a pull request to CoolProp on GitHub ). 

If you find the PC-SAFT parameters for any new fluids that aren't already available, and with a verified source document, I'd be happy to get them in there for you to help expand the database.  CoolProp is rebuilt nightly, so it would be a simple matter to download the development version of the Mathcad add-in from SourceForge with any new fluids added.
