Application of 2,3,4,6-Tetrachlorophenol_Kain Industrial Additive
Background and overview[1] Arsenic atomic absorption standard, also known as 2,3,4,6-tetrachlorophenol in Chinese, can be used as a pharmaceutical synthesis intermediate. Chlorophenols are a typical class of “three-causing (carcinogenic, teratogenic, mutagenic)” organic pollutants and are widely used in the production of preservatives, dyes, herbicides and pesticides. At the same time, chlorophenols by-products may also be produced during waste incineration, pulp bleaching, and drinking water chlorination and…
