Introduction
Methyl tert-butyl ether (MTBE) is a common organic compound with the chemical formula C5H12O. The following is an introduction to the properties, uses, preparation methods and safety information of methyl tert-butyl ether:Quality:- Appearance: Colorless liquid- Solubility: Soluble in water, alcohol and ether solvents- Melting Point: -110 °C- Boiling Point: 55-56°C(lit.)- Density: 0.7404Use:- Neutral solvent: MTL is often used as a neutral solvent in the chemical industry and can dissolve many organic substances.- Gasoline additives: MTE is added to gasoline to improve combustion efficiency and knock resistance, help reduce exhaust emissions, and improve the impact resistance of gasoline.- Chemical intermediates: MTBE is also an intermediate product of many chemical reactions and can be used to synthesize other organic compounds.Method:The common preparation method of methyl tert-butyl ether is obtained by the reaction of isobutylene with methanol. The reaction equation is as follows:C4H8 + CH3OH → C5H12OSafety Information:- MTL is flammable and should be stored in a cool, ventilated place in a cool and ventilated place, as it should avoid contact with open flames or high-temperature substances.- Avoid inhaling MTE vapor and avoid contact with skin and eyes.- MTL may have a negative impact on the environment, so environmental protection regulations should be observed when using and disposing of them.- Appropriate safety measures should be taken during industrial processes, including the wearing of personal protective equipment such as protective eyewear, respirators, and protective gloves.
