Other names: Trichlor methane
Its chemical formula is CHCl3 and it is a chemical agent that can easily evaporate and dissolve fat with an anesthetic effect. It is also known as triclormethane. It is a sweet, fragrant liquid and is not flammable. It converts into a toxic gas, phosgene, in the presence of flame. Used in chemical processes. It was found by Friedrich Moldenhauer in 1830 but it was named chloric ether because it was not recognized as a new substance. Chloroform is added to 0.5-1% alcohol to prevent oxidation, it undergoes oxidation slowly in the air with the effect of light.
Production and Reactions
Technically, it can be obtained by oxidation and chlorination of ethyl alcohol or acetone with lime scale or sodium hypochlorite. Chloroform can also be obtained technically by chlorination of methane. According to the chloroform oxidation reaction, the main product in the presence of oxygen is the fast and stable phosgene gas formed by dihydrochlorination of trichloromethanol. According to the reduction reaction, in the absence of oxygen, the main metabolite is carried out with dichloromethane free radical.
It is used in soil biomass determination in agriculture sector. In the fumigation process, the pressure is kept constant when chloroform starts to boil. Chloroform evaporates for 20-24 hours to contact with soil. The aim is to measure the microorganisms in the soil and to calculate the biological viability in the soil.
It can be used in many types of components in this sector.
It is used for plexiglass bonding in this sector.
