Catalytic conversion

A process for the conversion of a feedstock comprising carbon monoxide, hydrogen, and alcohol of from 1 to about 20 carbon atoms per molecule to product comprising an alcohol having a higher boiling point than said feedstock alcohol and an olefin which comprises contacting said feedstock under conversion conditions including a temperature of from about 100.degree. C. to about 400.degree. C., a pressure of from about 0.1 atmosphere to about 10,000 atmospheres, a contact time of from about 1 second to about 100 hours and a hydrogen/carbon monoxide mole ratio of from about 0.2 to about 5 with a catalyst comprised of a substrate of a porous refractory oxide having surface hydroxyl groups, a minimum surface area of about 10 m.sup.2 /g and pores with a minimum pore diameter of about 5 Angstrom Units, said substrate being modified by at least one amine functional member, containing the element silicon, coordinated to a metal function of a transition metal selected from the group consisting of Group VIII metals of the Periodic Table of Elements, said amine functional member acting as a bridging member between said substrate and said metal function, as a ligand covalently bonded to said substrate.
