Tetramethylammonium hydroxide poisoning

Clinical Toxicology, 2010
Tetramethylammonium hydroxide (TMAH) is widely used as a developer or etchant in semiconductor and photoelectric industries. In addition to alkalinity-related chemical burn, dermal exposure to TMAH may also result in respiratory failure and/or sudden death.

Characterization of the tetramethylammonium hydroxide thermochemolysis products of carbohydrates

Journal of Analytical and Applied Pyrolysis, 1999
Abstract The identification of the thermochemolysis products (in the presence of tetramethylammonium hydroxide, TMAH) of carbohydrates is presented. Analysis was carried out using on-line flash pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and off-line flash (vacuum) pyrolysis followed by GC/MS.

The effect of tetramethylammonium hydroxide in comparison with the effect of sodium hydroxide on the slow pyrolysis of cellulose

Journal of Analytical and Applied Pyrolysis, 2003
Abstract The effect of two bases, tetramethylammonium hydroxide (TMAH) used in thermally assisted hydrolysis and methylation (THM) analysis of biopolymers and NaOH generally used in cellulose and textile industry, was compared in the pyrolysis of cotton cellulose at very low concentrations using differential thermal analysis, data obtained from ...

Removal of acid from diesel by tetramethylammonium hydroxide/ethanol

Petroleum Science and Technology, 2016
ABSTRACTNaphthenic acid was removed by tetramethylammonium hydroxide as deacidification agent from diesel, and ethanol was used as extractant. The effect of parameters in the deacidification process was investigated systematically. The process parameters included mass fraction of deacidification agent, volume ratio of deacidification agent to diesel ...

Isolation and physiological properties of methanogenic archaea that degrade tetramethylammonium hydroxide

Applied Microbiology and Biotechnology, 2023
Tetramethylammonium hydroxide (TMAH) is a known toxic chemical used in the photolithography process of semiconductor photoelectronic processes. Significant amounts of wastewater containing TMAH are discharged from electronic industries. It is therefore attractive to apply anaerobic treatment to industrial wastewater containing TMAH.

"Mercerization" of Cotton with Tetramethylammonium Hydroxide

Textile Research Journal, 2003
Bleached cotton fabric is treated with an aqueous solution of tetramethylammonium hydroxide (TMAH) or with sodium hydroxide in various concentrations with or without tension. The degree of "mercerization" is characterized by the crystallinity, iodine sorp tion capacity, water retention values before and after drying, dye uptake, and color strength. The

Methanogenic degradation of tetramethylammonium hydroxide by Methanomethylovorans and Methanosarcina

Journal of Hazardous Materials, 2018
This study evaluated the methanogens responsible for methanogenic degradation of tetramethylammonium hydroxide (TMAH) in a continuous flow bioreactor. The enriched methanogens attained an estimated maximum specific TMAH degradation rate and half-saturation constant of 39.5 mg TMAH/gVSS/h and 820 mg/L, following the Monod-type kinetic expression for ...
