Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 141-84-4, Name is Rhodanine, SMILES is O=C1CSC(=S)N1, belongs to thiazolidines compound. In a document, author is Mamedov, I. G., introduce the new discover, Application In Synthesis of Rhodanine.
SOME ACETOPHENONE DERIVATIVES AS CORROSION INHIBITORS
The inhibition activities of 2-hydroxy-5-methylacetophenone thiosemicarbazone (1), (Z)-2-(((E)-1-(2-hydroxy-5-methylphenyl)ethylidene)hydrazono)thiazolidin-4-one (2), (E)-3-(2-hydroxy-54(E)-phenyldiazenyl)phenyl)-1-phenylprop-2-en-1-one (3), (E)-1-(4-bromophenyl)-3- (2-hydroxy-5-((E)-phenyldiazenyl)phenyl)prop-2-en-1-one (4), (E)-5-(2-hydroxy-5- (phenyldiazenyl)phenyl)-3-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide (5), (E)-3-(4-bromophenyl)-5-(2-hydroxy-5-(phenyldiazenyl)phenyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (6), 2, 2 ‘-((1 E, 1’E)-(ethane- 1, 2-diylbis(azanylylidene))bis (methanylylidene))bi s (4- ((E)- phenyldiazenyl)phenol (7) and 24(Z)-2-hydroxy-54(E)-phenyldiazenyl)benzylidene)hydrazine-1-carbothioamide (8) were explored by means of weight loss measurements for mild St-3 specimen in brine-kerosene solution. The corrosion rates of the St-3 drops as the inhibitor concentration increases together with increase of inhibition efficiencies. Thermodynamic parameters of adsorption on the St-3 surface at different concentrations were calculated.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 141-84-4 is helpful to your research. Application In Synthesis of Rhodanine.
