^aGeneral conditions: neat 11, 150 psi ethylene, 40 °C.

^bTime to maximum conversion.

^cConversion = 100 − [(final moles of 11) × 100/(initial moles of 11)].

^dSelectivity = (moles of ethenolysis products 12 + 13) × 100/(moles of total products 12 + 13 + 14 + 15).

^eYield = (moles of ethenolysis products 12 + 13) × 100/(initial moles of 11) conversion × selectivity/100.

^fTON = yield × [(moles of 11)/(moles of cat.)].
