METHOD FOR PREPARING ISOALKANES C OR C Russian patent published in 2004 - IPC

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to heterogenous-catalytic conversions of organic compounds, namely, to catalytic conversions of aliphatic alcohols to isoalkanes C₈ or C₁₀. Isoalkanes C₈ or C₁₀ are prepared by contacting aliphatic alcohol isobutanol or isopentanol in inert gas medium at 300-420 C, under pressure 30-80 atm, at volume rate 0.1-0.8 C₈ with catalytic composition comprising hydride phase of iron-titanium intermetallic compound modified with metals of IV-VII groups of Periodic system of the elements and industrial alumoplatinum or alumonickel catalyst taken in the mass ratio = 10:1. EFFECT: enhanced yield of isoalkanes, expanded raw base of parent reagents. 3 cl, 5 tbl, 21 ex
