Benzaldehyde CAS 100-52-7 is an organic compound formed after the hydrogen of benzene is replaced by aldehyde group. Benzaldehyde is the simplest and most commonly used aromatic aldehyde in industry. At room temperature, it is a colorless liquid with a special almond smell.
Preparation methods of CAS 100-52-7 Benzaldehyde
Benzaldehyde is mainly oxidized by toluene in gas phase with air or oxygen under the action of catalyst (vanadium pentoxide, tungsten trioxide or molybdenum trioxide); Or chlorinating toluene into benzyl chloride under light, and then hydrolyzing and oxidizing; It can also be chlorinated into dichloromethylbenzene and then hydrolyzed. In industry, benzene is also used as raw material to react with carbon monoxide and hydrogen chloride under pressure and under the action of aluminum trichloride. Benzaldehyde was prepared by catalytic reduction of benzoyl chloride in laboratory.
