The thermodynamic properties of saturated and superheated formaldehyde were evaluated at ten degree temperature intervals from -19°C. to 400°C. and at various pressures up to 150 atmospheres.

Lydersen's correlations were used to estimate the critical constants.

Vapor pressure data were calculated using Riedel's method.

The generalized thermodynamic correlations of Hougen, Lydersen,'and Greenkorn were employed to obtain values of the thermodynamic properties in the saturated and superheated regions.

The values for temperature, pressure, specific volume, enthalpy, and entropy for saturated and super-heated formaldehyde are presented in the form of tables and graphs.
