Abstract
Tetralin was pyrolyzed at a temperature and pressure regimen similar to the petroleum refining process known as delayed coking. Conditions employed were: temperature 450°C, pressure 600 kPa and reaction times of 60 to 300 min. The product composition was analyzed by combined capillary column gas chromatography-mass spectrometry. For all reaction time periods, naphthalene was the major product observed. Other significant products included: 1,2-dihydronaphthalene, 1-methylindan, n-butylbenzene and a tetralin-1-methylindan adduct. Minor products included: indene, decalin,toluene, ethylbenzene, styrene and n-propylbenzene. Gas analysis showed hydrogen, methane, ethene and propene as additional reaction products. The mechanisms of both major and minor product formation are described.
