The regioisomeric effect, which refers to the different positions of heteroatoms and functional groups on a molecule, significantly impacts stability, physicochemical properties, chemical reactivity, coordination bonding organic compounds. These effects are critical for their commercial applications, notably in corrosion inhibition. Regioisomeric ligands, with unique spatial configurations groups, influence ability establish stable interactions metal surfaces. Certain regioisomers may exhibit enhanced affinity adsorption capacities based structural configurations, thereby facilitating formation more durable protective layer substrate. This review explores impact regioisomerism inhibition performance A literature survey reveals that identical substituents (e.g., –OH, –NH2, –COOH, –NO2, –OR), multiple bonds >CC< –CC–), or N, O, S) at varying diverse capabilities efficiencies. detailed analysis indicates certain regioisomers, due strategic placement achieve increased stability form relatively stronger complexes. enhances effectiveness chelation mechanisms. role group has been seldom observed documented previous studies. current research also underscores significance determining ligands. thorough understanding will assist scientists engineers developing effective inhibitors.

Effective fluid-loss control in oil wells is a critical concern for the industry, particularly given substantial reserves situated carbonate reservoirs globally. The prevalence of such expected to rise with slow depletion hydrocarbons, intensifying need address challenges related deteriorating reservoir properties post well-killing operations. This deterioration results significant annual losses hydrocarbon production at major enterprises, impacting key performance indicators. To tackle this issue, study focuses on enhancing technology efficiency abnormally low formation pressures. authors propose development new blocking compositions that prevent fluid loss treatment fluids by productive reservoir. research tasks include comprehensive analysis global experience technology; compositions; an investigation their physico-chemical, rheological, and filtration properties; evaluation effectiveness complicated conditions. technology’s application gas condensate fields Volga-Ural province showcases its practical implementation. provides valuable insights solutions improved reservoirs, ultimately well recovery.

This article describes the results of a comprehensive comparative study production fatty acid ethyl esters (FAEEs) for use as biodiesel in perfect mixing reactors (PMRs) and plug flow (PFRs). The products obtained on laboratory scale at all stages separation purification FAEE phase were analyzed using FTIR, XRF GC-MS methods. We compared distillation methods stoichiometrically excessive ethanol from reaction mixture. Neutralization with H2SO4 solution carbonation CO2 applied catalyst. Emulsions formed during water flushing stage via optical microscopy method. optimal conditions stirring speed temperature selected to maintain high level FAEE–water contact area minimum time. efficiency method catalyst neutralization has been proven, allowing us consider this an alternative traditional According experimental studies, we have developed new high-performance technological scheme PFRs. synthesis FAEEs stoichiometric excess about 1:50 allowed increase rate productivity unit after transition PMR PFR. yield product amounted 86.7%. purified fraction complied most EN14214 specifications.

This article presents the prospect of using process deep hydrodesulfurization and hydrodearomatization secondary gas oils highly active NiMo catalysts to obtain hydrocarbon bases for drilling fluids. Catalysts were synthesized PMo heteropolyanions, citric acid, diethylene glycol on alumina carriers with different pore volumes. study showed that concentration impregnating solution affects composition morphology phase particles prepared catalyst, while textural characteristics carrier influence physicochemical properties catalytic activity NiMo/Al2O3 catalysts. The catalyst was a largest volume an effective diameter more than 7 nm exhibited highest activity. It demonstrated use such allows procurement fluids from mixtures at hydrogen pressure 15–20 MPa. has practical significance development sustainable economically efficient methods utilization low-quality petroleum produce high-margin environmentally friendly non-fuel products, as well contributes technologies raw materials.
