Acetone is generated upon mesityl oxide (MO) adsorption on TiO 2 at 35°C. Water plays an important role in promoting MO decomposition to form acetone. It is suggested that diacetone alcohol plays a role in the transformation of MO to acetone. The thermal reaction of pinacol on TiO 2 mainly produces pinacolone at a temperature higher than 100°C. However, acetone is mainly formed in the photocatalytic decomposition of pinacol on TiO 2 in O 2 . Pinacolone is thermally transformed into 2,3‐dimethyl‐1,3‐butadiene in the absence of O 2 and into pivalate in the presence of O 2 . Both the reactions of pinacolone occur above 200°C.
