What is Benzoic Acid?
Benzoic mountain is an organic link which is explained by the chemical formula C6H5COOH. It consists of a carboxyl team attached to a benzene ring. Therefore, benzoic mountain is stated to it is in an aromatic carboxylic acid. This link exists as a crystalline, colorless heavy under normal conditions. The ax ‘benzoate’ describes the esters and salts the C6H5COOH.

The commercial manufacturing of benzoic acid is done via the partial oxidation of toluene through oxygen, catalytic analysis by manganese or cobalt naphthenates. This chemistry reaction is portrayed below.
Another industrial technique of prepare benzoic mountain is by reacting tri-chlorotoluene through calcium hydroxide in the existence of water, and the therapy of the calcium benzoate product v hydrochloric acid.
The structure of a C6H5COOH molecule is portrayed below. This molecule is composed of a benzene ring to which a carboxyl functional group is linked. The molecule is composed of 7 carbon atoms, 6 hydrogen atoms, and also 2 oxygen atoms.

Frequently request Questions
What space the provides of benzoic acid?
The main use that benzoic acid is in the commercial production of the fragrant compound phenol. This is excellent via a process known together oxidative decarboxylation. It have the right to be noted that the ideal temperature under which this process can be lugged out is in the variety of 300 to 400 levels celsius. Also, benzoic acid and also its salts room widely offered in the food market as food preservatives.
Comment on the solubility the benzoic acid in water
Benzoic mountain is not very soluble in water. However, the solubility the this compound in water increases when the temperature is increased (as is the situation with most compounds). At a temperature that 0 levels celsius, the solubility of benzoic mountain in water coincides to 1.7 grams per litre. When heated come 100 levels celsius, the solubility of this compound in water rises to 56.31 grams per litre.
How deserve to benzoic mountain be prepared?
Industrially, benzoic acid have the right to be prepared by employing oxygen gas for the partial oxidation the toluene. It have the right to be noted that this process usually employs manganese or cobalt naphthenate as catalysts. This link can also be ready via the hydrolysis that benzamide and benzonitrile. It can also be ready by oxidizing benzyl chloride or benzyl alcohol, or any type of other derivative of the benzyl group.
