Interactions between coal matrix and organics are vital for adsorption, surfactant adsorption on lignite, and solid-liquid separation of coal slurry. Herein, for studying the interaction between hydrophobic surface (coal surface) and small mols. (organics), we measured interactions between organics [nitro and Ph, pyridine, Ph, alkyl chain (hexyl) or cycloalkyl (hexyl)] and the coal matrix (liptinite or inertinite) using at. force microscopy. The strength of interaction followed the order: nitro and Ph > pyridine > Ph >alkyl chain (hexyl)> cycloalkyl (hexyl), and liptinite > inertinite. The liptinite has a greater hydrophobicity than inertinite, the greater the attraction force. The lignite surface and coal slurry were modified in an aqueous solution using five surfactants (dodecyl tri-Me ammonium chloride, DTAC; hexadecyl tri-Me ammonium chloride, CTAC; octadecyl tri-Me ammonium chloride, STAC; hexadecyl di-Me benzyl ammonium chloride, HDBAC; and cetyl pyridine chloride, CPC). Subsequently, the moisture adsorption on treated lignite coal surface and the sedimentation of the treated tails was compared to characterize hydrophobic modifications which showed the order of CTAC > HDBAC > DTAC > CPC > STAC. Thus, the interaction between coal surface and organics needs to consider two rules: 1) The desolvation or the hydrophobic property of the coal surface; 2) The VDW force of the organics The nature of the difference between rules Number 1 and 2 is that with the size of hydrophobic mols. increased to a surface, the H-bond structure between water mols. in the around would change a lot, which formats great hydrophobic property or desolvation. Interaction between organic reagents and coal reveals the mechanism of restraining moisture reabsorption of lignite and solid-liquid separation of coal slurry by organics This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Formula: C25H46ClN).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Formula: C25H46ClN
