HCID 10438Phorone

Procedure

Acetone, first percolated through a bed of alumina, was passed through a reactor containing 0.54 g of ZSM-5 zeolite having a silica-to-alumina ratio of 26,000 to 1 and an Na content of 1.48%. No condensation products were observed at reaction temperatures below 200° C. (392° F.). When the reactor containing zeolite was heated to 280° to 370° C. (536°-698° F.), about 10% of the acetone fed was converted to mesityl oxide. Some phorone was also formed.
