Abstract
The problem of contamination of chlorophenolic biocides with polychlorinated dibenzo-n-dioxines and dibenzofurans formed as admixtures in the process of preparation synthesis is considered. Results of assay of chloroorganic admixtures in the sodium pentachlorophenolate synthesized in this country are presented. A high toxicity of the preparation determined by the content of less chlorinated congenerics of polychlorinated dibenzo-n-dioxines is demonstrated.
