What is 4-tert-Butylcatechol?

Description

Para-tertiary butyl catechol is specially prepared by reacting the impure catechol fraction with tertiary butyl alcohol. Used for its various properties (inhibition of polymerization and as an antioxidizing agent) in the manufacture of rubber, plastics and paints, in the preparation of petrolatum products, and as an antioxidant in oils, it may induce vitiligo.

The Uses of 4-tert-Butylcatechol

Polymerization inhibitor for styrene-butadiene and other olefins.
Inhibitor-remover packings and ready-to-use, disposable prepacked columns offer a quick and convenient means of removing small amounts of inhibitors which are added to reagents or solvents that would otherwise be unstable (e.g., they may polymerize, oxidize or darken) on storage.
The inhibitor removers are useful in applications which require that the stabilizer or inhibitor [i.e., hydroquinone (HQ), hydroquinone monomethyl ether (MEHQ, 4-methoxyphenol) or 4-tert-butylcatechol (TBC)] be removed prior to use.
