as an electron acceptor, while a negative value of ∆N indicates that the molecules act
as electron donors. Thus, from Table 4, all the molecules studied act as electron
acceptors except ∆E which acts as electron donor. According to Lukovits, if ∆N < 3.6,
the molecules can be assumed to posses charge transfer ability towards the metal
surface [13-15]. The inhibition potential of 2-propanol extract pomaces the apricotis
attributed to the presence of aldehyde – Phenylacetaldehydeand (9Z)-Octadec-9-enoic
acid.
CONCLUSION
This paper presents the apricot pomace extract that is areach source of antioxidant
compounds with promising potential as a component of cosmetic andpharmaceuticalas
well as anticorrosion ingredients. Moreover, the extract pomaces and the grapes are
effective inhibitors of corrosion of mild steel exposed for the temporary protection.It
is shown that the inhibition of the atmospheric corrosion of steels after treatment in the
vapor of volatile compounds the extract pomaces the apricot occurs due to the blocking
of the metal surface by chemically adsorbed molecules.The quantum-chemical
calculations were carried out to predict the adsorption activity of the main components
of extract pomaces the apricot. It is shown that the inhibition of the atmospheric
corrosion of steels after treatment in the vapor of volatile compounds of the 2-propanol
extract pomaces the grapes occurs due to the blocking of the metal surface by
chemically adsorbed molecules. The anticorrosion efficiency of the extract is ensured
by aldehyde – 2-Phenylacetaldehyde, 3,7-dimethylocta-2,6-dienal and (9Z)-Octadec-
9-enoic acid.
