Description |
Inhibitors are known for their specificity
of action.1 A substance, which effectively
protects a given metal under
certain conditions, may cease to be
effective under other conditions or with
other metals. The extracts of some common
plants and by-products (peels, seeds,
fruit shells, leaves, etc.) contain different
organic compounds (e.g., amino acids,
tannin, alkaloids, and most of their constituents),
which are known to have inhibitive
action.2-6 It is therefore expected
that the essential oils extracted from plants
would exhibit inhibitive action.
Vapor corrosion inhibitors (VCIs) are
chemicals that are used to protect metallic
items from atmospheric corrosion
during manufacture, storage, and transportation.
Initially, camphor was used to
protect military equipment and machinery
parts.6 In later years, the development
of organic compounds as VCIs for metals7-
10 has been important. Our previous
work11-12 revealed that the extracts of bark
oils and amine-azole-nitro compounds
are quite effective in reducing the corrosion
of mild steel in marine and industrial
environments. Jasminum grandiflorum (JG),
Jasminum auriculatum (JA), Oleum palmarosae
(OP), Ocimum basilicum (OB), and Vetiveria
zizanioides (VZ) oils were used in this work.
