Descrição geral

Tris(2,4-di-tert-butylphenyl) phosphite is a triaryl based phosphite that can be used in catalysis and metallation. Its characteristic to undergo metallation reaction and provide a cost effective synthetic processes allows it to be useful in biaryl coupling reactions.

Aplicação

It may be used as a chain extender and a processing stabilizer that facilitate the production of stable polymeric materials, which include polylactic acid (PLA), polyolefins, etc.
