GUAIACOL 6JKA7MAH9C Overview Structure Names 24: Classification 5: Identifiers 15: Mixtures 1: Relationships 3 The reaction process of metal ions and guaiacol process was tracked by an in situ FT-IR (Mettler) spectrometer equipped with a peristaltic pump, as shown in Figure 1. Guaiacol (0.042 mol) was added to distilled water (50 mL), and the pH value was adjusted to 11.5 using 30% NaOH aqueous solution for reserve.

The Brief Profile summarizes the non-confidential data on substances as it is held in the databases of the European Chemicals Agency (ECHA), including data provided by third parties. The Brief Profile is automatically generated; note that it does not currently distinguish between harmonised guaiacol in the presence of Al3+ indicated that there might be different binding modes between guaiacol and Al3+. The multiple interactions between Al3+ and guaiacol in the presence of Al−O and Al···H were investigated by in situ Fourier transform infrared spectroscopy, and they inhibited the production of the double condensation Guaiacol () is a naturally-occurring organic compound with the formula C 6 H 4 (OH) (OCH 3 ).
