The kinetics and mechanism of the thermolysis of tetralin, commonly used as a hydrogen donor in coal liquefaction, was studied under about 100 atm and within 385—485 ℃. Analysis of the products was carried out by G.C.with glass capillary column and F.I.D., G.C.-M.S., N.M.R.. The reaction was performed in a microreactor which was contructed by a small stainless steel tube. Dehydrogenation of tetralin to naphthylene and isomerization to l-methylindan were found to be dominate paths, while cracking of the C_B—C bound of tetralin to butyl benzene is subordinated. The small quantities of indan, toluene and ethylbenzene are believed to be derived from the further thermolysis of methyl indan and butylbenzene.A detailed kinetic analysis was given and the kinetic parameters were obtained. Combined with the thermokinetics calculations, a mechanism of the tetralin thermolysis was suggested.
