Tetramethylammonium Acetate Used as a Corrosion Inhibitor in Saline Environments for Oil and Gas Flow Assurance Applications

Tetramethylammonium Acetate Used as a Corrosion Inhibitor in Saline Environments for Oil and Gas Flow Assurance Applications Qasim, Ali, et al. Materials Today: Proceedings 47 (2021): 1355-1358.

Tetramethylammonium acetate (TMAAc), a quaternary ammonium salt (QAS), has been investigated for its potential application as a corrosion inhibitor in saline environments, relevant to flow assurance in the oil and gas industry. QAS compounds are widely recognized for their ability to adsorb onto metal surfaces and form protective films that suppress corrosion. In this study, the corrosion mitigation performance of TMAAc was evaluated using the weight loss method across a concentration range of 0.01-10 wt%.
Experimental results revealed that TMAAc exhibited corrosion inhibition only at low concentrations. Specifically, at 0.01 wt% (equivalent to 100 ppm), the corrosion rate was minimized at 0.068 mm/yr, indicating effective inhibition. However, increasing the concentration of TMAAc beyond 0.01 wt% resulted in a rise in corrosion rate, reaching 0.176 mm/yr at the highest tested concentration (10 wt%). This suggests that at elevated concentrations, TMAAc may promote rather than inhibit corrosion.
The findings demonstrate that TMAAc functions effectively as a corrosion inhibitor only at dilute concentrations, making it suitable for application in the 50-100 ppm range typically used in oil and gas systems. The study underscores the importance of dosage optimization for QAS-based inhibitors and confirms the potential of TMAAc as a viable corrosion control agent under specific operational conditions.

Tetramethylammonium Acetate Used for Reactive Derivatization in Two-Step Pyrolysis-Gas Chromatography of MAA-Containing Terpolymers

Tetramethylammonium Acetate Used for Reactive Derivatization in Two-Step Pyrolysis-Gas Chromatography of MAA-Containing Terpolymers Takeuchi, Kaoru, Hiromi Aoi, and Hajime Ohtani. Journal of Analytical and Applied Pyrolysis 113 (2015): 22-26.

Tetramethylammonium acetate (TMAAc) plays a critical role in the reactive derivatization of polar methacrylic acid (MAA) units in styrene-butyl acrylate-MAA terpolymers, enabling accurate compositional analysis via two-step pyrolysis-gas chromatography (Py-GC). In conventional Py-GC, direct analysis of MAA-containing polymers is hindered by the non-volatile, polar nature of the MAA moiety. The innovative use of TMAAc overcomes this limitation through in-situ methylation.
In the first step, the terpolymer sample was dissolved in tetrahydrofuran (THF) and premixed with TMAAc. A defined aliquot was introduced into a microfurnace pyrolyzer and heated at 200 °C for 10 minutes. This condition was optimized to convert MAA units into methyl methacrylate (MMA) with high efficiency and minimal side reactions. In the second step, pyrolysis at 600 °C produced depolymerized volatile fragments suitable for GC analysis. The resulting pyrogram displayed distinctive peaks corresponding to each monomeric unit, including MMA (from MAA), butyl acrylate, and styrene derivatives.
Quantitative analysis based on flame ionization detection (FID) confirmed the accuracy of this approach, with the estimated molar composition closely matching the feed ratio and relative standard deviations under 0.25%. TMAAc thus serves as a reliable derivatization reagent for characterizing polar-functionalized polymers via reactive Py-GC.

TetraMethylAmmonium Acetate (TMAAc) Used for the Selective Derivatization and Direct Analysis of Wood Extractives via RTD-GC

TetraMethylAmmonium Acetate (TMAAc) Used for the Selective Derivatization and Direct Analysis of Wood Extractives via RTD-GC Yokoi, Hiroaki, et al. Journal of analytical and applied pyrolysis 67.1 (2003): 191-200.

TetraMethylAmmonium Acetate (TMAAc) has been successfully applied as a reactive agent in a novel, rapid, and solvent-free method for the direct characterization of wood extractives using reactive thermal desorption-gas chromatography (RTD-GC). In this study, powdered Eucalyptus camaldulensis wood (≈100 μg) was mixed with 2 μL of aqueous TMAAc and subjected to thermal desorption at 200 °C in a vertical microfurnace pyrolyzer coupled directly to a GC-FID system.
TMAAc facilitates in situ methylation of polar extractives such as fatty acids, phenolic acids, and gallocatechins, yielding volatile methyl derivatives suitable for chromatographic analysis. The mild desorption temperature effectively suppresses pyrolysis of the lignocellulosic matrix, enabling selective detection of low-molecular-weight extractives with high sensitivity and reproducibility (RSD ~5%).
The derivatized compounds were transferred in splitless mode to a polydimethylsiloxane-coated capillary column and resolved under a controlled oven temperature program. Peak identification was achieved by coupling the pyrolyzer to a GC-MS system, confirming the structural integrity of the derivatized products.
This RTD-GC approach using TMAAc eliminates cumbersome pre-extraction and transmethylation steps, offering a streamlined alternative for quantifying wood extractives. The technique demonstrates TMAAc's utility as a clean, efficient methylating agent in applied analytical pyrolysis.
