“…It is also in accord with a random isotope distribution between the aromatic ring and the side chains. Therefore, secondary isotope scrambling within the xylene molecules formed was assumed and has been proven by the conversion of m-xylene labeled by 14 C-methyl groups [58,64]. For example, Dermietzel et al [58,64] applied 14 C-ethylbenzene labeled at different positions to reveal isotope scrambling during ethylbenzene conversion (Table 4).…”

AESTRACTToluene disproportionation based a chemical model by thermodynamic way was studied. The d i s t r i b u t i o n of reaction products was c a l c u l a t e d by computer(Fe1ix C-256). Disproportionation of toluene w a s a l s o c a r r i e d o u t using NaY z e o l i t e s as c a t a l y s t s , where t h e c a t i o n w a s exchanged with Lak, Cek, Co2+, Sr2+ ions and t h e composition of r e a c t i o n mixture w a s determinated by gas chromatograpby. A good agreement between t h e conversions c a l c u l a t e d by thermodynamic way and experimental data w a s noticed proving t h a t t h e discuSsed model can be applied.

A general procedure for the synthesis of labelled hydrocarbons by catalytic isomerization in a microreactor is described. At four studied reactions (synthesis of isohexanes, methylcyclopentane, methylcyclopentenes and xylenes) the thermodynamically expected equilibrium concentrations could be approached. For product separation a direct coupling of the microreactor with a prep‐scale gaschromatographic unit is favorable.
