Öğe New schiff base ligand derived from 4-aminoantipyrine: Synthesis and spectroscopic characterization(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, ReşitÖğe Synthesis and anticorrosion studies of 4-[(2-nitroacetophenonylidene)-amino]-antipyrine on SAE 1012 carbon steel in 15 wt.% HCl solution(Taylor & Francis, 2020-11-16) Gerengi, Hüsnü; Çakmak, Reşit; Dağ, Beşir; Solomon, M. M; Tüysüz Akbal, Hatice Aslıhan; Kaya, ErtuğrulA novel corrosion inhibitor, ((E)-1,5-dimethyl-4-((1-(3-nitrophenyl)ethylidene)amino)-2-phenyl-1,2-dihydro-3H-pyrazol-3-one) (DNPP) was synthesized in high yield by the condensation reaction of 4-aminoantipyrine with 2-nitroacetphenone derived from acetophenone as a starting material and characterized by FT-IR, 1H, and 13C NMR techniques. DNPP was tested against the corrosion of SAE 1012 carbon steel in 15 wt.% HCl solution using electrochemical and surface characterization techniques. Results obtained show that DNPP is effective in retarding the corrosion of SAE 1012 carbon steel. With 4 mM of DNPP, the charge transfer resistance of SAE 1012 in 15 wt.% HCl solution is raised from 17.42 to 140.50 Ω cm2 and the substrate surface is protected by 87%. The inhibition is through adsorption mechanism (mixed-adsorption type) and has been confirmed by SEM and EDAX results. Potentiodynamic polarization results reveal that DNPP acted as a mixed-type corrosion inhibitor. DNPP is a promising candidate for the formulation of an inhibitor cocktail for the strong acid environment.Öğe The amide derivatives of L-tyrosine: Synthesis and spectroscopic characterization(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, ReşitÖğe Synthesis, characterization of novel some schiff base ligands derived from 4-aminoantipyrine(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, ReşitÖğe Design, synthesis, and spectral characterization of schiff bases derived from 4-aminoantipyrine(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, ReşitÖğe New nitroaromatic esters derived from salicylaldehyde: Synthesis and characterization(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, ReşitÖğe Preparation, characterization of novel some schiff base ligands derived from 4-aminoantipyrine as a potential corrosion inhibitor(Azərbaycan Dövlət Neft və Sənaye Universiteti, 2017) Dağ, Beşir; Yaşar, Fevzi; Çakmak, Reşit
