| Abstract: | Cyclocondensation
of acetone involves aldol condensation leading initially to the primary
condensation products (PCP), diacetone alcohol and mesityl oxide, which again
react with acetone to form phorone, isophorone, mesitylene, etc. Relative
selectivities of chromia,  -alumina, magnesia and calcium oxide catalysts have
been studied in a flow reactor at 360-520°C. Alumina and magnesia are found to favour
isophorone formation at 360°C with 45% selectivity but the selectivity steeply
falls with the increase in temperature to 520 °C due
to rise in decomposition products. Primary condensation products are formed
more with magnesia; selectivity to mesitylene is more with CaO (~66% at 400-480
°C) and Cr2O3 (50-55% at 480-520 °C. |
