[3] [7] Commercial or laboratory-grade xylene produced usually contains about 40–65% of m-xylene and up to 20% each of o-xylene, p-xylene and ethylbenzene. [8] [9] [10] The ratio of isomers can be shifted to favor the highly valued p-xylene via the patented UOP-Isomar process [11] or by transalkylation of xylene with itself or trimethylbenzene.
There are three xylenes and one ethylbenzene. The substances are: Xylenes. o-xylene (1,2-dimethylbenzene), m-xylene (1,3-dimethylbenzene) p-xylene (1,4-dimethylbenzene)

Ethylbenzene hydroperoxide is the organic compound with the formula C 6 H 5 CH(O 2 H)CH 3. A colorless liquid, EBHP is a common hydroperoxide. It has been used as an O-atom donor in organic synthesis. It is chiral. Together with tert-butyl hydroperoxide and cumene hydroperoxide, ethylbenzene hydroperoxide is important commercially. [1]
In all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.
