This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Propionic acid (/ p r oʊ p i ˈ ɒ n ɪ k /, from the Greek words πρῶτος : prōtos, meaning "first", and πίων : píōn, meaning "fat"; also known as propanoic acid) is a naturally occurring carboxylic acid with chemical formula CH 3 CH 2 CO 2 H. It is a liquid with a pungent and unpleasant smell somewhat resembling body odor. The ...

The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere. log refers to log base 10 (T/K) refers to temperature in Kelvin (K) (P/Pa) refers to pressure in Pascal (Pa)

Industrial route to propionic anhydride involves thermal dehydration of propionic acid, driving off the water by distillation: 2 CH 3 CH 2 CO 2 H → (CH 3 CH 2 CO) 2 O + H 2 O. Another routes is the Reppe carbonylation of ethylene with propionic acid and nickel carbonyl as the catalyst: [1] CH 2 =CH 2 + CH 3 CH 2 CO 2 H + CO → (CH 3 CH 2 CO) 2 O
