Abstract
The dec-1-ene transformations were studied in the presence of Y, Beta, ZSM-12 and ZSM-5 zeolites in the H-form. It is established that the main products of the reaction in the presence of zeolites H-Y, H-Beta, H-ZSM-12 are dec-1-ene isomers and its oligomers, while in the presence of zeolite H-ZSM-5 dec-1-ene isomerization predominantly occurs. The mentioned catalytic systems can be arranged in the following series by the activity: H-Beta > H-Y > H-ZSM-12 >> H-ZSM-5, and by the selectivity of oligomers: H-ZSM-12 > H-Beta ~ H-Y >> H-ZSM-5 in the temperature range of 150-220 °С. Among oligomers the dimers of decene are predominant, have an alkyl-naphthenic structure, contain unsaturated hydrocarbons with tri- and tetra-substituted double bonds of 2.2-3.2 % was established. Physicochemical properties of the synthesized decene oligomers are similar to the hydrogenated poly-α-olefins obtained on the catalytic AlCl3 complexes.
