Mainly used as gasoline additive, has excellent knock resistance, improve the octane number, can also be cracked to produce isobutene.It has good miscibility with gasoline, less water absorption, no pollution to the environment, and can be improved as an analytical solvent and extractant.In chromatography, especially high pressure liquid chromatography used as removal agent, and some polar solvents such as water, methanol, ethanol and so on azeotrope formation.

Methyl tert-butyl ether also has a mild anesthetic effect.

Storage Method:

Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the warehouse should not exceed 37℃. Keep the container sealed. Should be stored separately from oxidizer, do not mix storage. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that are prone to spark. The storage area should be equipped with leak emergency treatment equipment and suitable holding materials.
