Benzenesulfonamide, 4-ethyl- (9CI) - Introduction
p-ethylbenzenesulfonamide is an organic compound with the chemical formula C8H9NO2S. The following is the introduction of the properties, uses, preparation methods and safety information of ethyl benzene sulfonamide:
Nature:
p-Ethylbenzenesulfonamide is a white crystalline solid with a pungent odor. It is soluble in water and organic solvents, but hydrolyzes under acidic conditions. It is highly corrosive and flammable when encountering fire sources.
Use:
p-Ethylbenzenesulfonamide is widely used in the field of organic synthesis. It can be used as a catalyst to catalyze the oxidation of hydrocarbons. In addition, it can also be used as dyes, fungicides, pharmaceutical intermediates and other raw materials.
Preparation Method:
The preparation of p-ethylbenzenesulfonamide can be completed by the ethylation reaction of p-toluenesulfonamide. The specific step is to react toluene sulfonamide with ethanol under the catalysis of sulfuric acid to generate p-ethyl benzene sulfonamide. Subsequent preparation steps include crystallization, filtration, washing, etc.
Safety Information:
p-Ethylbenzenesulfonamide is an irritating compound. During use, safety measures need to be strengthened to avoid contact with skin, eyes or breathing, and a well-ventilated working environment needs to be ensured. Appropriate personal protective equipment such as lab gloves, goggles and protective clothing should be worn during operation. In addition, p-ethylbenzenesulfonamide should be stored in a dry, cool place, away from fire and oxidizing agents. If inhaled or taken by mistake, seek medical attention immediately.
