Introduction | 2, 4-di-tert-butylphenol widely exists in plants and is also an important intermediate of fine chemical products, mainly used for the preparation of antioxidant 168, but also for the preparation of polyisobutylene, polyamide, polycarbonate, etc.; Can be used for the production of antioxidants (300, 314), UV absorbers, light stabilizers 120, dyes and textile auxiliaries, 2402 resin. In addition, it is also used for the synthesis of perfumes, activators 460, initiators TBCP, pesticide emulsifiers, especially additives. |
Use | can be used as an intermediate of antioxidant, stabilizer and ultraviolet absorber. used as antioxidant, UV absorber, etc. is an important intermediate of a variety of light stabilizers, antioxidants Antioxidant 168, antioxidant P-EPQ, light stabilizer 120,UV-327, UV-320, reclaimed rubber activator and other opportunities to synthesize intermediates for the synthesis of antioxidant 168, P-EPQ, light stabilizer 120UV-327, UV-320, UV absorber, reclaimed rubber activator 460, plasticizers, etc. The main raw materials for the preparation of phosphite antioxidants |
production method | results from the alkylation of phenol with isobutene. |
