Update FluidData.mo

[beutlich]

• Remove superfluous import of PartialMixtureMedium
• Fix number of records from 37 to 38
• Fix documentation (change spelling of "1-Heptane" to "1-Heptene", add "1-Butanol", fix columns (there is no such gas "Neon Oxygen"))
• Add gas name as record description
• Add IUPAC name where available (except CO2 and NO2)

However, I am wondering what the comment

ModelicaStandardLibrary/Modelica/Media/IdealGases/Common/FluidData.mo

Line 97 in bfc5dd0

hasAcentricFactor = true); // does not exist!

means and if the number of records should be 37. In any case, it should be clarified.

I don't feel confident in reviewing this chemical changes - as I'm not familiar with IUPAC.
E.g., I don't understand if "Azane" for Ammonia (NH3) is the correct name to use here, or if it is only intended to be used in some cases.

[HansOlsson]

I'm also a bit confused about 1-Heptene; as I understand it is https://en.wikipedia.org/wiki/Heptene is C7H14 but just called Heptene without the 1 - although iupacName is given as hept-1-ene.

And https://en.wikipedia.org/wiki/Ammonia state that

IUPAC name Ammonia
Systematic IUPAC name Azane

I do not know enough about this topic to approve it. As I recall "hasAcentricFactor" was introduced by @hubertus65.

[beutlich]

I took "azane" (and the other IUPAC names) frome pubchem. Could be that "ammonia" is more common in literature though.

@hubertus65 @thorade I assume that comment is OK then, right?

[thorade]

Maybe the comment originally was in a different place?
Like this:

  constant Modelica.Media.Interfaces.Types.IdealGas.FluidConstants CO2(
                       chemicalFormula =        "CO2",
                       iupacName =              "unknown", // does not exist!
                       structureFormula =       "unknown",
                       casRegistryNumber =      "124-38-9",
                       meltingPoint =           216.58,
                       normalBoilingPoint =     -1.0,
                       criticalTemperature =    304.12,
                       criticalPressure =        73.74e5,
                       criticalMolarVolume =     94.07e-6,
                       acentricFactor =           0.225,
                       dipoleMoment =             0.0,
                       molarMass =              SingleGasesData.CO2.MM,
                       hasDipoleMoment =       true,
                       hasIdealGasHeatCapacity=true,
                       hasCriticalData =       true,
                       hasAcentricFactor =     true); 

I think Dymola would move that comment behind the semicolon in this case.
CO2 does exist :-)

[beutlich]

It has been in MSL like this since it first appeared.

There also is NO2 with iupacName = "unknown" and without that comment.

[hubertus65]

The acentric factor is defined via the boiling point at atmospheric pressure, and therefore it actually doesn't exist for CO2. With that clarification, and all approvals, I think it can be merged.
