2. Benzoic acid - Wikipedia

   en.wikipedia.org/wiki/Benzoic_acid

   Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...

3. Ortho effect - Wikipedia

   en.wikipedia.org/wiki/Ortho_effect

   When a substituent group is located ortho position to the carboxyl group in a substituted benzoic acid compound, the compound becomes more acidic surpassing the unmodified benzoic acid. Generally ortho-substituted benzoic acids are stronger acids than their meta and para isomers.

4. Benzyl alcohol - Wikipedia

   en.wikipedia.org/wiki/Benzyl_alcohol

   It oxidizes rapidly in healthy individuals to benzoic acid, conjugated with glycine in the liver, and excreted as hippuric acid. Very high concentrations can result in toxic effects including respiratory failure, vasodilation, hypotension, convulsions, and paralysis. Benzyl alcohol is toxic to neonates and is associated with the gasping syndrome.

5. Benzoyl chloride - Wikipedia

   en.wikipedia.org/wiki/Benzoyl_chloride

   It reacts with water to produce hydrochloric acid and benzoic acid: C 6 H 5 COCl + H 2 O → C 6 H 5 COOH + HCl. Benzoyl chloride is a typical acyl chloride. It reacts with alcohols to give the corresponding esters. Similarly, it reacts with amines to give the amide. [5] [6]

6. Benzaldehyde - Wikipedia

   en.wikipedia.org/wiki/Benzaldehyde

   Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...

7. Benzanilide - Wikipedia

   en.wikipedia.org/wiki/Benzanilide

   It is a white solid. Commercially available, it may be prepared by treating benzoic acid with aniline. [1] References This page was last edited on 5 June 2023 ...

8. Azeotrope tables - Wikipedia

   en.wikipedia.org/wiki/Azeotrope_tables

   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.

9. Birch reduction - Wikipedia

   en.wikipedia.org/wiki/Birch_reduction

   The Birch reduction is an organic reaction that is used to convert arenes to 1,4-cyclohexadienes.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 (traditionally an alcohol).
