cricondenbarn.

Brit.

/krɪˈkɒndənˌbɑː/, U.S.

/krɪˈkɑndənˌbɑr/

Origin: A borrowing from Greek, combined with English elements. Etymons: critical adj., condensation n., Greek βάρος.

Etymology: < cri- (in critical adj.) + conden- (in condensation n.) + -bar (in ancient Greek βάρος weight, βαρύς heavy: see baro- comb. form), after cricondentherm n.

Physical Chemistry.

The maximum pressure at which two phases of a substance (for example, liquid and vapour) can coexist.

1944 B. F. Dodge Chem. Engin. Thermodynamics xii. 545 This point has been given no name but by analogy to the cricondentherm point it might be called a ‘cricondenbar’.

1966 Science 14 Jan. 189/1 Those who would like to drop such neologisms as cricondenbar and salaquifer into future discussions would be well advised to procure a copy.

1981 E. J. Hoffman Phase & Flow Behavior ii. 25 The curves of constant liquid/vapor ratios may exhibit a zero slope (dP/dT = 0) in a certain region of the phase diagram. Such a point is called a cricondenbar.

2006 Jrnl. Chem. Thermodynamics 38 1489/1 It is necessary to size compressors for operation at a pressure considerably above the predicted cricondenbar.
