Description

Heterocyclic triazinyl quaternary ammonium salt and preparation and application thereof
Technical Field
The invention belongs to the technical field of metal corrosion and protection, relates to a quaternary ammonium salt corrosion inhibition bactericide, and particularly relates to a heterocyclic triazinyl quaternary ammonium salt corrosion inhibition bactericide and application thereof in inhibiting sulfate reducing bacteria corrosion.
Background
Microbial corrosion (Microbiologically influenced corrosion, MIC) refers to the phenomenon in which the corrosion of metallic materials is accelerated directly by the self-life activities of microorganisms or indirectly by their metabolites. It has been counted that the economic losses due to metal corrosion account for about 3-5% of GDP per year, with the economic losses due to microbial corrosion accounting for about 20% of the total economic losses (Chinese corrosion and protection journal, 2021, 41 (1): 1-12.).
Microorganisms involved in MIC mainly include sulfate-reducing bacteria (Sulfate reducing bacteria, SRB), iron-oxidizing bacteria (Iron-oxidizing bacteria, IOB), iron-reducing bacteria (IRB), acid-producing bacteria (Acid-producing bacteria, APB), and the like. It was investigated that in the known MIC case, SRBs were present and involved in one half. Thus, SRB is the primary species responsible for microbial corrosion.
For a long time, the most common method for controlling microbial corrosion is to add a bactericide, which can kill microorganisms and inhibit microbial corrosion. However, after a period of use, bacteria can develop drug resistance, so that the dosage and use cost of the bactericide are increased continuously, and the economic and environmental burden is increased. On the other hand, bactericides are effective against planktonic microorganisms, but hardly kill microorganisms in biofilms. Therefore, it is necessary to design a highly effective corrosion inhibiting bactericide against SRB corrosion and reduce the amount of bactericide used.
The quaternary ammonium salt surfactant has antibacterial and bactericidal functions, low toxicity and wide application range, and has a long history of research on the quaternary ammonium salt surfactant as a bactericide. Meanwhile, the quaternary ammonium salt surfactant can form directional adsorption at the interface, so that a compact protective film can be formed, corrosion of metal is slowed down, and the quaternary ammonium salt surfactant can also be used as a metal corrosion inhibitor.
However, it was found (Corrosion Science, 2017, 117: 24-34.) that SRB could still be locally adsorbed on the surface of the material to form a biofilm with significant localized pits of corrosion in the area where the biofilm was formed, at a mass concentration of 40mg/L of dimethyl alkyl ammonium chloride (alkyl chain length of 10-16).
The heterocyclic compound generally contains hetero atoms (such as N, S, O) with larger electronegativity in the molecule, so that lone pair electrons can be provided to form coordination bonds with the metal surface, and corrosion reaction is prevented; secondly, the heterocyclic compound has pi bond, and can act with the metal surface through a front line molecular orbit to prevent further corrosion reaction; in addition, due to the polarity of the molecules, the metal surface can be covered by electrostatic attraction, so that the corrosion process of the metal can be inhibited. Thus, heterocyclic compounds are commonly used in industry as corrosion inhibitors, but their bactericidal properties against microorganisms are relatively poor.
Disclosure of Invention
The invention aims to provide a heterocyclic triazinyl-containing quaternary ammonium salt, which has higher corrosion inhibition and sterilization efficiency when the use amount is small through the synergistic coupling effect of the same intramolecular heterocycle and the quaternary ammonium salt functional group.

More specifically, the invention provides application of the heterocyclic triazinyl-containing quaternary ammonium salt as a slow-release bactericide of carbon steel in the presence of sulfate reducing bacteria.
The molecular structure of the heterocyclic triazinyl-containing quaternary ammonium salt comprises an alkane chain, a heterocycle and a quaternary ammonium salt structure. The quaternary ammonium salt can be selectively adsorbed on the surface of a biological film of the SRB and permeate into a cell membrane, so that the biological functions of electron transfer, selective substance transfer, isolation barrier and the like of the cell membrane are changed, the selective permeability and genetic system of the cell membrane are destroyed, and the activity of the SRB is inhibited or even dead; on the other hand, the triazine ring and the heterocycle in the molecular structure have rich heteroatoms (N, S) and share pi electrons, and can form coordination bonds with empty d orbitals of iron to carry out chemical adsorption, so that the quaternary ammonium salt surfactant and the heterocyclic compound are combined, and the corrosion inhibition and sterilization performances of the quaternary ammonium salt surfactant and the heterocyclic compound can be further improved through the synergistic effect of the quaternary ammonium salt surfactant and the heterocyclic compound.
At the same time, the alkyl chain contained in the compound structure can form a layer of hydrophobic barrier to prevent invasion of corrosive ions and protect carbon steel from corrosion.

Example 3: and (3) measuring the surface activity of the heterocyclic triazinyl quaternary ammonium salt.
In this example, the surface activity of the heterocyclic triazinyl-containing quaternary ammonium salts prepared in example 1 and example 2 in simulated seawater was measured by the surface tension method.
SRB medium ingredients were added to a 3.5% NaCl aqueous solution to simulate a seawater environment. The SRB medium comprises the following components (g/L): k (K) 2 HPO 4 0.5，NH 4 Cl 1.0，Na 2 SO 4 1.0，CaCl 2 ·2H 2 O 0.1，MgSO 4 ·7H 2 O2.0, DL-sodium lactate 2.0, yeast extract 1.0.
A series of heterocyclic triazinyl quaternary ammonium salt-containing solutions with different concentrations are prepared by using the simulated seawater, and the equilibrium surface tension of the heterocyclic triazinyl quaternary ammonium salt-containing solution is measured by using a K100 automatic surface tension meter and adopting a platinum ring method.
FIG. 5 is a graph showing the relationship between the surface tension and the concentration of the heterocyclic triazinyl-containing quaternary ammonium salt obtained from the measurement results. CMC values of BTOTB and MTOTB in simulated seawater at 30deg.C are 0.035mM and 0.11mM, respectively, corresponding to surface tension gamma CMC 32.8 mN.m respectively -1 And 35.7 mN.m -1 。
Example 4: and (3) measuring the minimum inhibitory concentration of the heterocyclic triazinyl quaternary ammonium salt.
The minimum inhibitory concentration of the heterocyclic triazinyl quaternary ammonium salt was determined in this example using a standard 2-fold dilution method.
1) Diluting the activated SRB bacterial liquid with sterile culture medium to obtain bacterial load of 10 6 Bacterial liquid of the order of magnitude of individual/mL.
2) Preparing a certain amount of heterocyclic triazinyl quaternary ammonium salt mother liquor by using a sterile culture medium, adding the mother liquor into 10mL test tubes according to a standard 2-fold dilution method to obtain a series of concentration gradients, and adding 1mL of the bacterial liquid into each test tube (the final bacterial liquid is 3-7 multiplied by 10) 5 and/mL).
3) Three parallel test tubes were set for each concentration and incubated at 30℃for 14d.
4) The color change of the medium in the tube was recorded. When SRB grows in the culture medium, black FeS precipitation is generated, and otherwise, the SRB does not change color. When all three test tubes are not discolored, the corresponding concentration is the lowest antibacterial concentration of the bactericide.
The corresponding minimum inhibitory concentrations for the products of example 1 and example 2 are listed in table 1 with dodecyldimethylbenzyl ammonium chloride (1227) as a reference. It can be seen that BTOTB and MTOTB have significantly better bacteriostatic effect on SRB than 1227.
