1. Why can't acetylene cylinders be used up?The gas in the bottle is used up, the pressure inside the bottle is balanced with the atmospheric pressure, and the air is easily mixed into the bottle to form a mixture of acetylene and air. The explosion limit of acetylene is 2.3%-100% (volume fraction).

Acetylene can be used to illuminate, weld and cut metal (oxygen flame), and is also a basic raw material for producing acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fibers and the like.When acetylene is burned, it can generate high temperature. The temperature of oxyacetylene flame

Ethylene is a colorless anesthetic gas having a characteristic sweet smell of hydrocarbons at normal temperature and pressure. It is chemically active and forms an explosive mixture with air. It is extremely flammable and explosive. It can be combined with chlorine gas under the sun to cause an expl
