Catalytic properties of ASM amorphous mesoporous aluminosilicates with different SiO2/Al2O3 molar ratios (20, 40, 80) in oligomerization of 1-pentene and isoamylene fraction were studied. The yield of pentene oligomers is maximal on ASM-20 aluminosilicate and decreases with an increase in the SiO2/Al2O3 molar ratio. The optimum conditions for preparing 1-pentene oligomers in the maximal yield (92–94%) were determined: 150–180°C, 10% catalyst. The yields of the oligomers obtained from the isoamylene fraction on ASM-20 and ASM-40 aluminosilicates are 76 and 74%, respectively (110°C, 10% catalyst), with dimers prevailing. Comparison of the catalytic properties of ASM-20 and 40 mesoporous aluminosilicates and H-Beta zeolite in oligomerization of these monomers shows that their activity is close, but the mesoporous materials exhibit higher stability in oligomerization. In addition, ASM aluminosilicates allow preparation of oligomers with broader molecular-mass distribution.
