Dihydrobenzene, also known as dehydrobenzene, is an organic compound with the molecular formula C6H4(CH3)2. It is a colorless liquid with a sweet odor and is soluble in common organic solvents such as alcohol and ether. Dehydrobenzene belongs to the benzene ring family and is an important intermediate in the chemical industry.

The preparation of dehydrobenzene mainly involves two methods: dehydration of toluene and dehydration of ethylbenzene. In the dehydration of toluene, toluene is reacted with sulfuric acid at high temperature and high pressure to produce dehydrobenzene and water. This reaction is reversible, so the separation of products and reactants is necessary to ensure the yield of dehydrobenzene. In the dehydration of ethylbenzene, ethylbenzene is reacted with sulfuric acid at high temperature and high pressure to produce dehydrobenzene and water. This method has a higher yield of dehydrobenzene compared to the dehydration of toluene.

Dehydrobenzene has important applications in the chemical industry. It is mainly used in the production of styrene, which is a key raw material for the production of polystyrene, styrene
