Experiments were conducted to elucidate the mechanism of reaction between guaiacol and Ca(OH)2 in water based on in situ FT-IR, 1H NMR, ICP-AES and TGA analyses. Three phases were revealed for this reaction when guaiacol was dropped into the solution of Ca(OH)2, and the final molar ratio of guaiacol to Ca2+ reaches 4. It was found that an acid–base reaction occurs in the first reaction phase. However,...
