Conclusions 1. The technique of mass spectrometric thermal analysis has been used to establish that on heating rutile, modified by acetic acid, to 300°C, separation of physically adsorbed acetic acid, together with acetic acid formed by the thermal hydrolysis of surface acetates, takes place from the surface. Above 300°C, disruption of the surface acetates begins with the formation of acetone, ketene, water, and carbon dioxide. 2. Disruption of a methanol layer adsorbed on the surface of rutile begins at 200–300°C by loss of molecules of alcohol, both physically adsorbed and formed by thermal hydrolysis of surface esters, from the surface. At 300–400°C, the surface methanol compounds decompose with the separation of dimethyl ether, formaldehyde, and saturated and unsaturated hydrocarbons.
