Abstract:

Derivatives of 2-amino-4,6-di-tert-butylphenol exhibit antiviral properties and radical regulatory activity against various types of organic radicals which determines the actuality of their further investigation. But the question of aminophenol derivatives immunomodulatory activity remains open. In this regard, the aim of the study was to assess the effects of 2-amino-4,6-di-tert-butylphenol derivatives on the viability and functional potential of human peripheral blood lymphocytes. As a result of the studies, it was shown that aminophenol compounds at concentrations of 10–5–10–7 mol did not e

<strong>ABSTRACT</strong> 4-tert-Octylphenol (OP) is major degradations products of alkylphenol ethoxylates. These chemicals are found in the waste water and sludge of sewage treatment works and river sediments. Alkylphenols are also found in drinking water.  Thus, alkylphenols are widely dispersed in the environment. Several alkylphenols, including 4-tert-octylphenol have included altered sex hormone levels and hypothalamic-pituitary outcomes, impaired spermatogenesis 4-tert-octylphenol is not considered directly genotoxic.

Abstract:

It is known that in order to restrain the process of oxidation of transformer oil, and, accordingly, to extend its service life, an antioxidant additive ionol is added to it. Previously, specialists using the method of chromato-mass spectrometry established the fact of the formation of new phenolic compounds in oil along with the consumption of the inhibitory additive ionol, namely, 2,6-di-tert-butylphenol (2,6-DTBP) and 2, 6-di-tert-p-benzoquinone. These phenolic compounds, as well as ionol, belong to the class of sterically hindered phenols, which, in turn, are able to inhibit the oxidation
