Aromaticity-Guided Synthesis and Reactivity of Heterocyclic Compounds: Structural Insights and Applications
Abstract: The concept of aromaticity serves as a fundamental framework for understanding the structural and electronic characteristics of heterocyclic compounds, which play a crucial role in modern synthetic chemistry. Aromatic compounds, characterized by cyclic planar systems with delocalized π-electrons, follow the Hückel rule, conferring significant stability to heterocyclic structures. The incorporation of heteroatoms, such as nitrogen, oxygen, and sulphur, within these rings profoundly influences electron distribution, molecular reactivity, and synthetic pathways. …

Reactive Separation for Biodiesel Purification Using Hybrid Membrane Systems
Abstract: Biodiesel produced through transesterification typically contains several impurities, including residual glycerol, unreacted methanol, soaps, water and homogeneous catalysts, all of which reduce fuel quality and hinder compliance with EN 14214 and ASTM D6751 standards. Conventional purification techniques such as water washing, centrifugation and vacuum distillation are energy-intensive, generate large volumes of wastewater and often fail to efficiently remove polar contaminants. To overcome these limitations, this study examines a reactive separation …
