Definitions
- TBDS di-tert-butyl sulfide
- TBM tert-butyl mercaptan
- the invention relates to the use of di-tert-butyl sulfide (TBDS) and / or tert-butyl mercaptan (TBM) for inhibiting the microbial corrosion of metals and their alloys, in particular steel.
- TBDS di-tert-butyl sulfide
- TBM tert-butyl mercaptan
- the object of the invention can be achieved by using di-tert-butyl disulfide (TBDS), tert-butyl mercaptan (TBM) or a mixture of both compounds.
- TBDS and TBM have proven to be inhibitors of microbial corrosion in that they prevent the attack of the microorganisms of the genus Thiobacillus on the sulfide layers.
- FeS 2 pyrite layers
- TBM is the actual active ingredient which prevents bacterial corrosion by forming disulfide bonds with the metal sulfides.
- the compounds according to the invention are preferably applied as a protective film to the metal surface to be protected. This can be done, for example Painting the compounds dissolved in water and / or an organic solvent. In the event that TBDS is applied as a layer, this must be activated so that TBDS is split into TBM.
- the cover layer is activated by UV treatment, heating, microwave treatment or plasma treatment.
- a solution of TBDS and TBM is used, e.g. an aqueous alcoholic solution.
- the TBDS is split into the TBM in this solution by adding alkali lye.
- the solution must be applied to the metal surface relatively quickly, so that not too much TBM is converted back into TBDS by air oxidation.
- This variant is quite suitable for the treatment of small metal surfaces, for the treatment of larger surfaces it is recommended to use TBDS due to the better handling.
- the compounds according to the invention are suitable for inhibiting corrosion for all metals or alloys on which sulfide layers can be formed, such as iron, copper, zinc, lead, nickel, cobalt or molbdenum.
- sulfide layers such as iron, copper, zinc, lead, nickel, cobalt or molbdenum.
- the use of the corrosion inhibitors according to the invention on steel has proven to be extremely effective.
- Organometallic chemical vapor deposition is a process for the preparation of thin polycrystals and epitaxial layers. The layers are deposited from the gas phase. Organometallic compounds mostly serve as starting materials (precursors). The separation process is as follows: A carrier gas is passed through so-called bubblers. The organometallic compounds are in liquid or solid form in the bubbler. The raw materials are thereby taken up in the carrier gas. The carrier gas transports the starting compounds past a heated substrate. The starting compounds contain the elements with which the layer is to be formed. In a reaction, the compounds decompose above the substrate surface. This releases the elements that contribute to layer formation. These accumulate on the substrate surface and thus form the layer. The excess decay products are fed into the exhaust air with the carrier gas.
- a carrier gas is passed through so-called bubblers.
- the organometallic compounds are in liquid or solid form in the bubbler.
- the raw materials are thereby taken up in the carrier gas.
- the carrier gas transports the starting compounds past a heated substrate.
- the pyrite layers were prepared with the MOCVD system as described in "Solar Energy Materials and Solar Cells" 1993, 29, 289-370.
- A) elemental sulfur and b) TBDS were used as the suitable sulfur precursor.
- Iron pentacarbonyl [Fe (CO) 5 ] was used as the iron precursor for the preparation of pyrite.
- Example la The pyrite layers produced in Example la) using elemental sulfur as a precursor were treated with a thin film of TBM in an isolation chamber.
- the layer was rinsed with plenty of water to remove the excess TBM.
- the layer was flotated and cultivated as in Example 2 with Tuovine medium and bacteria. It was surprisingly found that there was no bacterial corrosion, although it was to be expected that the reaction of TBM with sulfuric acid (Tuovine buffer) would result in H 2 S having a positive effect on the corrosion activity of the bacteria.
