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.

1. A process for preparing an α,ω-Cn-diol, comprising the steps: (a) providing a feedstock comprising a Cn oxygenate comprising 1,2,6-hexanetriol; and(b) contacting the feedstock with hydrogen gas, in the presence of a catalyst at a temperature and for a time sufficient to form a product mixture com
1. A process for preparing an α,ω-Cn-diol, comprising the steps: (a) providing a feedstock comprising a Cn oxygenate comprising 1,2,6-hexanetriol; and(b) contacting the feedstock with hydrogen gas, in the presence of a catalyst at a temperature and for a time sufficient to form a product mixture comprising an α,ω-Cn-diol, wherein n is 6; and wherein the catalyst comprises metals M1, M2, and M3, and optionally a support, wherein M1 is Mn or Cr; M2 is Ni, Co, or Fe; and M3 is Cu; orM1 is Pt or Rh; M2 is Cu, Ni or Pd; and M3 is Re or W. 2. The process of claim 1, wherein the optional support is present in the catalyst and comprises WO3, SiO2, Al2O3, carbon, TiO2, ZrO2, SiO2-Al2O3, montmorillonite, SiO2-TiO2, tungstated ZrO2, zeolites, V2O5, MoO3, or mixtures thereof. 3. The process of claim 1, wherein M1 is Mn or Cr; M2 is Ni, Co, or Fe; and M3 is Cu. 4. The process of claim 1, wherein M1 is Pt or Rh; M2 is Cu, Ni or Pd; and M3 is Re or W. 5. The process of claim 4, wherein M1 is Pt or Rh; M2 is Cu or Ni; and M3 is Re or W. 6. The process of claim 2, wherein the support comprises TiO2, a zeolite, or mixtures thereof. 7. The process of claim 1, further comprising the steps: (c) optionally, isolating the α,ω-Cn-diol from the product mixture;(d) contacting the α,ω-Cn-diol with ammonia and hydrogen in the presence of a reductive amination catalyst at a temperature and for a time sufficient to form a second product mixture comprising an α,ω-Cn-diaminoalkane, wherein the α,ω-Cn-diaminoalkane comprises 1,6-diaminohexane; and(e) optionally, isolating the α,ω-Cn-diaminoalkane from the second product mixture.
