Abstract

N,N'-di-isopropyl-urea is prepd. by batchwise or continuous reductive hydrogenation of urea in the presence of acetone in a ternary solvent mixt. using pure hydrogen or hydrogen mixed with an inert gas at 120-200 deg.C and a pressure of 5-14 MPa on a carrier supported catalyst. - Catalyst is pref. palladium, platinum, rhodium or nickel supported on a meta-oxide from the 8B gp. of the periodic table, pref. aluminum-oxide, or on an inert carrier. - Ternary solvent mixt. consists of 7-85 vol.% alcohol with 2-4 carbons, 10-20 vol.% acetone and 2-4 vol.% water.
