Properties and composition of the wastes of monoethanolamine treatment of hydrogen to remove carbon dioxide was written by Khitrin, S. V.;Fuks, S. L.;Devyaterikova, S. V.. And the article was included in Russian Journal of Applied Chemistry (Translation of Zhurnal Prikladnoi Khimii) in 2002.SDS of cas: 934-48-5 This article mentions the following:
The composition of the large-scale wastes from monoethanolamine treatment of pyrolysis hydrogen to remove carbon dioxide was studied. The bottoms after monoethanolamine treatment inhibit corrosion of steel with relatively poor and satisfactory protective power in acidic and neutral solutions, resp., whereas in the case of nonferrous metals they catalyze corrosion and can be used as polishing agent for copper and brass. The bottoms inhibit the atm. corrosion of steel at their content in solution of 75 mL/L. In the course of corrosion tests the content of primary and secondary amines increases. In the experiment, the researchers used many compounds, for example, 3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5SDS of cas: 934-48-5).
3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives. As is the case with imidazoles, the pyrazole ring offers many opportunities to create new multiring systems that incorporate this heterocycle. Pyrazole rings have been used as core components of several leading non-steroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. It has also been found to be useful as a bifunctional ligand for metal catalysis.SDS of cas: 934-48-5
