Title:
3,3’,5,5’-テトラ-t-ブチル-4,4’-ビフェノールを連続的に製造する方法
Document Type and Number:
Japanese Patent JP4201575
Kind Code:
B2
Abstract:
3,3',5,5'-Tetra-t-butyl-4,4'-biphenol (TBBP) is continuously produced by supplying 2,6-di-t-butylphenol to a first reaction section (1) of a reaction apparatus, supplying alkali catalyst to the first reaction section, and distributing oxygen-containing gas to each reaction section. Continuously producing TBBP comprises oxidizing/dimerizing 2,6-di-t-butylphenol comprises supplying 2,6-di-t-butylphenol to a first reaction section of a reaction apparatus in which at least the first reaction section and a second reaction section (2) are connected in series; supplying alkali catalyst to the first reaction section; and distributing oxygen-containing gas to each reaction section, respectively, where a reaction mixture containing TBBP is obtained.
