Synthesis, characterization and VOCs adsorption kinetics of diethylstilbestrol-substituted metallophthalocyanines

Abstract

Compound (4,4[Formula: see text] -hex-3-ene-3,4-diyl)bis(4,1-phenylene)bis(oxy)diphthalonitrile 3 was synthesized by the reaction of 4-nitrophthalonitrile 1 and diethylstilbestrol 2 in dry DMF in presence of dry K2CO3. New mononuclear phthalocyanines 4-6 were obtained from compound 3 by addition of the corresponding metal salts [Co(OAc)2 ⋅ 4H2O, Zn(OAc)2 ⋅ 2H2O and Cu(OAc)2]. The novel compounds were characterized by elemental analysis and FT-IR, UV-vis, 1H-NMR and MALDI-TOF mass spectroscopy techniques. The effects of four main groups of organic vapors on these novel compounds were studied and discussed. The adsorption kinetics of alkanes ([Formula: see text]-hexane and [Formula: see text]-octane), alcohols (methanol and 2-proponal), chlorinated hydrocarbons (dichloromethane and trichloromethane) and amines (diethylamine and triethylamine) on 4-6 were examined using three adsorption kinetic models: the Elovich equation, the pseudo-first-order equations and Ritchie’s equation. Results show that the linear regression analysis with respect to the pseudo-second-order rate equations generates a straight line that best fits the data of adsorption of alcohols and chlorinated hydrocarbons on Pc films. On the other hand, the Elovich equation generates a straight line that best fits the data of adsorption of alkanes and amines.

High-efficiency adsorption of Cd2+ and Cr3+ by sodium vanadate nanowire arrays

“…The adsorption of Cd 2+ and Cr 3+ by Na 5 V 12 O 32 is a complex process, and the main behavior and mechanism of the adsorption process can be analyzed by certain models. In this experiment, a pseudo-first-order dynamic model (Dao et al, 2022), pseudo-second-order dynamic model (Khamizov, 2020), and Elovich dynamic model (Kaki et al, 2019) were established to find the most suitable model for the…”

Adsorption and passivation behavior of copper alloy by phthalocyanine complexes in an aqueous chloride solution

“…В последнее время область применения ФЦ сильно расширилась в связи с открытием у них оптических и электрических свойств, а также термической устойчивости [6]. Для улучшения электрической, оптической и термической стабильности более 70 различных ионов металлов могут быть введены в центральную полость ФЦ [4,7].…”
