Abstract

Disclosed is a process for the amination of polyols to form primary amines which comprises reacting a polyoxyalkylene alcohol or polyol having a molecular weight of from about 230 to 5000 and ammonia in the presence of hydrogen over a catalyst consisting essentially of 10 to 35 wt % nickel, 1 to 20 wt % copper and 0.1 to 2.0 wt % optionally chromium or molybdenum promoter impregnated onto a .theta.-alumina support at a temperature of 100.degree. C. to 300.degree. C. and a pressure of 1000 psig to 3000 psig wherein the .theta.-alumina support results from calcining .gamma.-alumina or pseudo-boehmite for 2-4 hours at 900.degree.-1100.degree. C.
