How would you separate benzoic acid and salt?
Benzoic acid and salt both dissolve.
- Benzoic acid is only soluable in hot water – so cool the mixture and the benzoic acid comes out of solution and can be filtered out with filterpaper.
- The Salt can then be recovered by boiling the water until there is none left.
Does benzoic acid sublimes on heating?
(A) A mixture of comphor and benzoic acid cannot be separated by sublimation. (R) Camphor on heating sublimes but benzoic acid does not.

What is sodium benzoate used in?
preservative
Sodium benzoate is commonly used as a preservative in cosmetics and personal care items, such as hair products, baby wipes, toothpaste, and mouthwash ( 2 ). It also has industrial uses. One of its biggest applications is to deter corrosion, such as in coolants for car engines ( 2 , 7).
How do you make benzoic acid from benzotrichloride?
Benzoic acid is manufactured by treating molten phthalic anhydride with steam in the presence of a zinc oxide catalyst, by the hydrolysis of benzotrichloride, or by the oxidation of toluene with nitric acid or sodium bichromate or with air in the presence of a transition metal salt catalyst.
What is the melting point of benzoic acid?
Melting point of impure benzoic acid = 116 – 118 0C Melting point of purified benzoic acid = 118 – 119 0C Melting point of pure (ANALAR) benzoic acid = 118 – 119 0C

Can sodium benzoate improve cognitive function in early-phase Alzheimer’s disease?
Sodium benzoate was well-tolerated without evident side-effects. Sodium benzoate substantially improved cognitive and overall functions in patients with early-phase AD. The preliminary results show promise for D-amino acid oxidase inhibition as a novel approach for early dementing processes.
