Abstract—Quaternary ammonium compounds containing the hydroxyalkyl moiety in the head group have
been synthesized. These compounds exhibit a micelleꢀforming ability, high anticorrosive activity, and antimiꢀ
crobial action. The compounds of the formula R(CH3)2N+(CH2CH2CH2OH)Br– with R = C14H29–C18H37
are characterized by a protective effect higher than 90–99% at 10 mg/l with respect to hydrogen sulfide corꢀ
rosion, inhibiting properties against carbon dioxide corrosion (84–98% at 10–25 mg/l), and bactericidal
action on sulfateꢀreducing bacteria (10–50 mg/l).

Under the oil producing and refining conditions, ing surfactants, occupy an important place. In actual
metallic operation equipment experiences the impact
of corrosive media, frequently because of large
amounts of hydrogen sulfide and carbon dioxide [1, 2].
In addition to hydrogen sulfide corrosion, microbioꢀ
logical corrosion can also occur [1, 3]; most freꢀ
quently, this was explained by the activity of sulfateꢀ
reducing bacteria (SRB). However, the process can be
considerably intensified by the metabolic products of
other groups of microorganisms. Thus, it was shown
that the metabolic products of Aspergillus niger accelꢀ
erated the corrosion of aluminum, copper, and
iron [4].
practice, quaternary ammonium compounds (QACs)
are frequently used as surfactants, some of which
exhibit bactericidal action toward SRB [5–9].
The protective action of QACs is usually explained
by their adsorption on the surface of equipment; in
this case, the inhibiting effect increases if the inhibitor
occurs in a micellar state in solution [10]. The use of
compounds capable of aggregation (for example, surꢀ
factants) leads to the formation of a continuous layer,
which consists of micelles, on the metal surface at low
concentrations of QACs. Based on electronꢀmicroꢀ
scopic data, Gufurov et al. [5] hypothesized that the
formation of a film on the metal surface with the parꢀ
ticipation of micelleꢀforming inhibitors proceeds in
two stages. Initially, a continuous molecular film and,
then, a micellar layer are formed. Micelleꢀforming
inhibitors form this adsorption layer on any surface
regardless of its state. Therefore, the inhibiting effect
of these reagents does not decrease with changes in the
metal surface, for example, in the presence on it of
corrosion products [10].
Metal corrosion under the action of SRB was
mainly associated with the formation of hydrogen sulꢀ
fide and sulfides as a result of sulfate reduction.
Underground well equipment and overhead equipꢀ
ment, pipelines, and steel oil reservoir mainly suffer
from biocorrosion under the action of SRB and related
microorganisms in biocenoses. The biological nature
of corrosion damage in oil storage tanks was supported
by the fact that bactericides provided effective protecꢀ
tion against corrosion; however, the widespread use of
these agents is limited by their cost and scarce
resources.
The assortment of reagents capable of effectively
protecting metal in solutions containing hydrogen sulꢀ
fide and carbon dioxide and simultaneously possessing
bactericidal properties is very limited, although a large
number of corrosion inhibitors have recently been
developed. Largeꢀscale petroleum production is
Inhibitor protection is one of the most accessible
and economical means of corrosion control in oilꢀ
field equipment at all of the stages of oil production,
treatment, refining, and transportation. Among the
inhibitors of hydrogen sulfide and carbon dioxide corꢀ responsible for high requirements imposed on the effiꢀ
rosion, nitrogenꢀcontaining organic reagents, includꢀ ciency of these inhibitors, the accessibility of source
