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 ...
IUPAC name: Common name: Structural formula hexanoic acid: caproic acid n-caproic acid: CH 3 (CH 2) 4 COOH hexanedioic acid: adipic acid hexane-1,6-dioic acid: HOOC(CH 2) 4 COOH 2,3-dimethylbutanoic acid CH 3 (CHCH 3) 2 COOH 3,3-dimethylbutanoic acid CH 3 C(CH 3) 2 CH 2 COOH 2-hydroxypropane-1,2,3-tricarboxylic acid: citric acid 3-carboxy-3 ...
The molecular formula C 7 H 6 O 2 (molar mass: 122.12 g/mol, exact mass: 122.036779 u) may refer to: Benzoic acid; 1,3-Benzodioxole; Hydroxybenzaldehyde. Salicylaldehyde (2-hydroxybenzaldehyde) 3-Hydroxybenzaldehyde; 4-Hydroxybenzaldehyde; Tropolone
Some traditional names for common carboxylic acids (such as acetic acid) are in such widespread use that they are retained in IUPAC nomenclature, [7] though systematic names like ethanoic acid are also used. Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives ...

Sodium benzoate also known as benzoate of soda is the sodium salt of benzoic acid, widely used as a food preservative (with an E number of E211) and a pickling agent. It appears as a white crystalline chemical with the formula C 6 H 5 COONa.
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 ...
One very common way to make potassium benzoate is by oxidizing toluene to benzoic acid followed by a neutralization with potassium hydroxide: [5] C 6 H 5 COOH + KOH → C 6 H 5 COOK + H 2 O. Another way to synthesize potassium benzoate in the lab setting is by hydrolyzing methyl benzoate with potassium hydroxide: C 6 H 5 COOCH 3 + KOH → C 6 H ...
