According to the present invention, a deuterium-substituted marker for fuel is synthesized through substitution with deuterium so as to have structurally and chemically similar properties to those of a molecule configuring fuel oil. A molecule of the deuterium-substituted marker is significantly similar to the conventional molecule configuring the fuel oil, which may prevent illegal removal of the marker by the fake oil manufacturers. According to the present invention, it is able to pursue public safety and environmental protection from fake oil products, and to prevent national tax evasion, by preventing the illegal mixing of fuel oil to secure a legal distribution of the oil market according to the present invention.

A method of decomposing a phenol by-product produced in a phenol preparation process, in which acetophenone separated from a distillation column is mixed with tar separated and collected in a decomposition reactor, thereby significantly decreasing viscosity of tar. The decomposition method according to the present invention allows tar to have sufficient viscosity for flowability even at room temperature, whereby transfer and storage of tar may be more smoothly done without using any heating device for transfer of tar.

The disclosure concerns systems and methods for the production of phenol and acetone from cumene oxidation products. One method comprises reacting cumene and an oxidizing agent to produce a cumene oxidation product comprising cumene hydroperoxide and dimethyl benzyl alcohol, converting at least a portion of the dimethyl benzyl alcohol to cumene hydroperoxide by reacting the at least a portion of the dimethyl benzyl alcohol with hydrogen peroxide in both an organic phase and an aqueous to produce a converted cumene oxidation product, and cleaving the converted cumene oxidation product to produce an output product comprising one or more of phenol, acetone, and alpha-methylstyrene.
