Birch equation
WebBirch reduction. The Birch reduction is an organic reaction that is used to convert arenes to 1,4-Cyclohexadiene. The reaction is named after the Australian chemist Arthur Birch and involves the organic reduction of aromatic rings in an amine solvent (traditionally liquid ammonia) with an alkali metal (traditionally sodium) and a proton source ... WebJul 1, 2024 · The Birch and Down equation expresses humidity in terms of partial pressure of water vapor. Given the dew point (or frost point) t d, we convert to partial pressure p v using (3) where p sv (t d) is the saturation vapor pressure at the dew point (or at the frost point if appropriate).
