Preparation method of sodium 2

Background and overview[1-2] The composition of high-boiling chlorophenols is very complex, mainly containing o-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, 4-bromo-2,5-dichlorophenol, 4 , 4-dichlorodiphenylsulfone and dichlorophenoxychlorophenol, etc. Among them, chemical products with relatively high added value are o-chlorophenol, 2,4-dichlorophenol and 2,4,6-trichlorophenol. The content of 2,4,6-trichlorophenol is the largest among high-boiling chlorophenols, at about 55 wt%, while the content of…
