متن کاملThe use of tetramethylammonium hydroxide in the Zimmermann reaction.
The use of tetramethylammonium hydroxide (T.M.A.H.) in place of potassium hydroxide in the Zimmermann reaction has been investigated. Although various pure steroids have different colour equivalents, a comparison of the results of 17-ketosteroid and 17-hydroxycorticosteroid estimations on a series of urines showed that the differences for the two reagents were only small and may be ignored. Tet...
متن کاملAbstract: Tetramethylammonium Hydroxide Poison- ing during a Pallet Cleaning Demonstration: Seung-
Tetramethylammonium (TMA) is a well-known ganglion blocker and was first extracted from the sea anemone in 1923. Today, TMA’s hydroxide, tetramethylammonium hydroxide (TMAH), is used as a developer, etchant and polishing agent in the semiconductor manufacturing process, as well as a surfactant to prevent agglomeration. One national survey found that about 20,000 tons of TMAH are being used in K...
متن کاملPyrolysis of lignin in the presence of tetramethylammonium hydroxide (TMAH): products stemming from beta-5 substructures.
Lignin model compounds, synthetic lignins, and cedar wood have been analyzed by pyrolysis-gas chromatography(-mass spectrometry) in the presence of tetramethylammonium hydroxide (TMAH) to examine the behavior of beta-5 substructures specifically under these conditions. Two model compounds contained a beta-5 linkage and a gamma-CH2OH group. The phenolic model compound produced stilbene products ...
متن کاملToxicity of tetramethylammonium hydroxide to aquatic organisms and its synergistic action with potassium iodide.
The aquatic ecotoxicity of chemicals involved in the manufacturing process of thin film transistor liquid crystal displays was assessed with a battery of four selected acute toxicity bioassays. We focused on tetramethylammonium hydroxide (TMAH, CAS No. 75-59-2), a widely utilized etchant. The toxicity of TMAH was low when tested in the 72 h-algal growth inhibition test (Pseudokirchneriellia sub...
