Abstract
Disclosed are a method of preparing polyaromatic oxide and polyaromatic oxide prepared thereby, wherein the method includes (a) placing a plurality of kinds of polyaromatic hydrocarbons and water in a reactor and then stirring them; (b) increasing the temperature inside the reactor to 150 to 300° C. and then feeding a gas containing 10 wt % or more of oxygen into the reactor to increase the partial pressure of oxygen inside the reactor to 2 to 30 bar; and (c) reacting the plurality of kinds of polyaromatic hydrocarbons with oxygen to oxidize the plurality of kinds of polyaromatic hydrocarbons.
