Curation notes

Identity VALIDATED_WITH_WARNINGS by the library. Printed pp. 1061-1155; pages cited are pdf pages.

IDEAL GAS AND CONSTANTS: M = 16.0428(13) g/mol and R = 8.31451(21) J/(mol K) (p. 5, printed 1064); the ideal-gas part (Eq. 3.8, p. 27; Table 27) is fitted to McDowell and Kruse’s (1963) values, +-0.015 %. T_c = 190.564 K. Range 90.6941-625 K, 1000 MPa.

AGAINST COOLPROP 8.0.0 (reference key Setzmann-JPCRD-1991): the same M, R and ideal part (computed 2026-09-30).
