An intracrystalline catalytic esterification reaction between ethylene glycol intercalated layered double hydroxide and cyclohexanecarboxylic acid

• Ethylene glycol (EG) intercalated LDH was synthesized.
• Intracrystalline esterification occurs between EG in LDH and cyclohexanecarboxylic acid.
• LDH sheets act as esterification catalysts.
• This reaction shows a much higher deacidification efficiency than bulk reaction.

An intracrystalline catalytic esterification between ethylene glycol intercalated NiAl layered double hydroxide and cyclohexanecarboxylic acid is developed. It leads to much higher deacidification efficiency than the bulk catalytic reaction. The intracrystalline catalytic reaction mechanism has been proposed.

An intracrystalline catalytic esterification between EG anions pre-immobilized in layered double hydroxide and cyclohexanecarboxylic acid was constructed. Apparently, a higher deacidification ratio than that of the bulk catalytic reaction was obtained.Figure optionsDownload as PowerPoint slide
