Abstract:
1. A process for oxidizing an alkyaromatic compound to the corresponding alkyaromatic hydroperoxide, the process comprising contacting an alkylaromatic compound of general formula (I): in which R wherein each of R each of Q each of X and Z is independently selected from C, S, CH Y is O or OH; k is 0, 1, or 2; l is 0, 1, or 2; m is 1 to 3; and R wherein said contacting is conducted at a temperature of about 120° C. to about 150° C. and a pressure of between about 15 kPa and about 500 kPa, said cyclic imide is present in an amount between about 0.05 wt % and about 5 wt % of the alkylaromatic compound in said feed, and said catalyst is substantially free of alkali metal compounds, said contacting oxidizing at least part of the alkylaromatic compound in said feed to the corresponding alkylaromatic hydroperoxide.
