4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol.[1] TBC is available in the form of a solid crystal flake[2] and 85% solution in methanol[3] or water.[4]
Uses
It is added as a stabilizer and polymerisation inhibitor to butadiene, styrene,[5] vinyl acetate, divinylbenzene[6] and other reactive monomer streams.[7]
TBC is also used as a stabilizer in the manufacture of polyurethane foam.[8] It also can be used as an antioxidant for synthetic rubber, polymers and oil derivatives.[7] It can be used as purification agent for aminoformate catalysts.[citation needed]
It is 25 times better than hydroquinone at 60 °C for polymerization inhibitory effect.[citation needed]
