Some new synthesized pyrazole organic-type compounds have been tested as inhibitors for the corrosion of iron in 1M HCl by weight-loss and electrochem. polarization methods. Both technique gave the same order of inhibition. The compound 1,3-bis(3′-chloromethyl-5′-methyl-1′-pyrazolyl)propane (Inh.9) was the best inhibitor and its inhibition efficiency increased with increasing concentration, reaching 95% at 4.10-4M. Polarization measurements have shown that the pyrazole substances studied inhibited both the anodic reaction of iron dissolution and the cathodic reaction of hydrogen evolution. These products act without changing the mechanism of the cathodic hydrogen evolution reaction. The corrosion inhibition of pyrazole studied is regarded by a simple blocked fraction of the electrode surface related to adsorption of inhibitor species according to Langmuir isotherm model on the iron surface. The introduction in the pyrazole ring of a substitute such as -OH, -CO2H, -CO2CH3, and -Cl in the position 3, enhances the inhibiting effect of the pyrazole compounds The effect of temperature on the corrosion behavior of iron indicated that inhibition efficiencies of (Inh. 9) increased with increasing temperature in the range of 25-50°C. The apparent activation energy for iron corrosion process are modified by addition of (Inh. 9). In addition to this study using (3-methyl-1H-pyrazol-5-yl)methanol, there are many other studies that have used (3-methyl-1H-pyrazol-5-yl)methanol(cas: 29004-73-7Application of 29004-73-7) was used in this study.
(3-methyl-1H-pyrazol-5-yl)methanol(cas: 29004-73-7) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Application of 29004-73-7
