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.

Benzyl alcohol (also known as α-cresol) is an aromatic alcohol with the formula C 6 H 5 CH 2 OH. The benzyl group is often abbreviated "Bn" (not to be confused with "Bz" which is used for benzoyl), thus benzyl alcohol is denoted as BnOH. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic odor.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O , it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis .
Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl alcohol can be formed from benzaldehyde by means of hydrogenation . Reaction of benzaldehyde with anhydrous sodium acetate and acetic anhydride yields cinnamic acid , while alcoholic potassium cyanide can be used to ...
It is usually prepared by the dehydration reaction of benzoic acid, e.g. using acetic anhydride: [3] 2 C 6 H 5 CO 2 H + (CH 3 CO) 2 O → (C 6 H 5 CO) 2 O + 2 CH 3 CO 2 H. Alternatively, sodium benzoate can be treated with benzoyl chloride. It can be produced by dehydrating benzoic acid by heating. [citation needed]
Benzoic acid (/ b ɛ n ˈ z oʊ. ɪ k /) is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent.
