Abstract
1387396 Hydrodealkylation INSTITUT NEFTEKHIMICHESKOGO SINTEZA IMENI AV TOPCHIEVA AKADEMII NAUK SSSR 1 June 1973 [5 June 1972] 26289/73 Heading C5E Aromatic hydrocarbons are produced by rapidly compressing a gaseous reaction mixture containing an alkylaromatic hydrocarbon and hydrogen to raise the temperature of the mixture to between 1000‹ and 1800‹ C. The hydrodealkylation may be carried out in an adiabatic compression unit having a free piston or a reciprocal compression reactor. Examples describe the hydrodealkylation of toluene, xylene and α-methylnaphthalene.
