Introduction
Properties of p-ethylbenzoic acid: It is a colorless or yellowish liquid with a special aromatic odor. P-ethylbenzoic acid is soluble in alcohol and ether and insoluble in water.
Uses of p-ethylbenzoic acid: Ethylbenzoic acid can also be used in the preparation of coatings, inks, and dyes.
Preparation method of p-ethylbenzoic acid:
The preparation of p-ethylbenzoic acid is usually done by catalytic oxidation of ethylbenzene with oxygen. Transition metal oxides, such as molybdate catalysts, are commonly used for catalysts. The reaction takes place at the right temperature and pressure to produce p-ethylbenzoic acid.
Safety information for ethylbenzoic acid:
Ethylbenzoic acid has an irritating effect on the eyes and skin, and should be rinsed with plenty of water in time when in contact. Appropriate personal protective equipment such as safety glasses and gloves should be worn during operation.
