DETERMINATION OF COMPOSITION OF REACTION MIXTURES FROM ALKYLATION OF TOLUENE ON PHOSPHORUS-MODIFIED H-ZSM-5 ZEOLITE

Determination of analytical composition of reaction mixtures formed by alkylation of toluene with ethylene on a phosphorus-modified H-ZSM-5 zeolite was made by capillary high resolution gas chromatography.Identification of individual components on these reaction mixtures was performed by GC-MS method, using the samples obtained at 320 and 400 deg C on H-ZSM-5 catalyst (modul 43.6) modified with 3.4 wt.percent phosphorus at toluene to ethylene molar ratio 4.5:1 and the catalyst loading expressed as weight hour space velocity WHSV (for toluene) = 6.9 h-1.The reaction mixtures contained a total 86 hydrocarbons.It was confirmed that in addition to the main alkylation reaction, there proceeds also ethylene oligomerization with subsequent cyclization and aromatization, disproportionation, alkylation and cyclization reactions of alkylaromatic hydrocarbons to give alkylnaphthalines and alkylindanes.
