Critical Constants: 2-Pentyne
Critical constants (Tc, Pc, Vc, Zc) and acentric factors for pure chemical compounds. Covers 1143 organic and inorganic compounds from Perry and CRC Handbook. Used in equations of state (Peng-Robinson, SRK, van der Waals), corresponding-states correlations, and thermodynamic property estimation.
