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 ...

It is the ester of propanol and propionic acid. Like most esters, propyl propanoate is a colorless liquid with a fruity odor. The scent of propyl propionate is described as a chemically tinged pineapple or pear. It is used in perfumery and as a solvent. [2] [3] The refractive index at 20 °C is 1.393.

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
