How Is it Manufactured?

Tertiary Amyl Benzene is manufactured from amyl alcohol and hydrochloric acid. When these two chemicals are mixed, the temperature of the mixture increases rapidly and it produces tertiary amyl chloride. Then tertiary amyl chloride is mixed with methyl benzene to yield tertiary amyl benzene.


Industry Applications

  • Tertiary Amyl Benzene (TAB) is a vital intermediary chemical for the production of hydrogen peroxide (H202). It helps in the production of 2-Amyl-anthraquinone (AAQ) which is used in hydrogen peroxide production.
  • As it is a crucial component of electrolyte of Lithium-ion batteries, TAB prevents the overheating of these batteries, helping in eliminating the dangers of fire and explosion.
  • Tertiary Amyl Benzene (TAB) has a high oxidation initiation charge so it doesn’t react too early, thereby protecting the batteries from overcharging. Due to these properties, TAB is widely used in batteries for smartphone devices and small electronic devices.
  • Its role is also becoming integral in the electric vehicle manufacturing industry. TAB is used as a solvent as well for many chemical processes.
  • TAB is a key chemical component for the synthesis of an API that has antifungal properties and is used in numerous pharmaceutical synthesis processes.
