Abstract

Disclosed herein are processes for preparing an α,ω-Cn-diol, wherein n is 5 or greater, from a feedstock comprising a Cn oxygenate. In some embodiments, the process comprises contacting the feedstock with hydrogen gas in the presence of a catalyst comprising metals M1, M2, and M3 and optionally a support, wherein: M1 is Mn, Cr, V, or Ti; M2 is Ni, Co, or Fe; and M3 is Cu, Ag, Pt, Pd or Au; or M1 is Pt or Rh; M2 is Cu, Ni or Pd; and M3 is Mo, Re or W. The Cn oxygenate may be obtained from a biorenewable resource.
