Patent ID: 7161038

Claim:
A process for producing polyoxyalkylene triamine, comprising: bringing a polyoxyalkylene triol represented by formula (I): wherein A represents a normal or branched alkylene group having 2 to 6 carbon atoms, “A” may be the same as or different from one another, x, y and z are each an average mole number of alkyleneoxy groups added to each oxygen atom, and the total of x+y+z is from 1 to 100 into contact with ammonia and hydrogen in the presence of a catalyst, wherein the catalyst comprises ruthenium metal in an amount of 0.5 to 20% by weight of the total weight of the catalyst, the ruthenium metal is carried on at least one carrier selected from the group consisting of alumina, silica, silica-alumina, titanium dioxide and titanium dioxide-silica, and wherein the mole ratio of the ammonia to one OH group of the polyoxyalkylene triol is from 1/1 to 11/1.
