The synthesis of ketene and dimethylketene have been investigated on functionalized silica monoliths from acetic acid and isobutyric acid respectively. With contact times of about 10 milliseconds, yields of ketene and dimethylketene of 70% per pass are routinely achieved. These results indicates that the control of contact time is a valid strategy for synthesis of ketenes.
