Abstract Prepn. of non-symmetric substd. ureas (I) effected by reacting a gaseous mixt. of isocyanic acid and NH3 at 250-600 deg.C with a prim. or sec. amine. The reaction is pref. effected by either (a) introducing 1-7 (esp. 1.1-3) equivs. of the amine (pref. at 320-380 deg.C) into a gaseous isocyanic acid/NH3 mixt. and then cooling (pref. using an inert diluent) to condense (I); or (b) introducing a gaseous unisocyanic acid/NH3 mixt. at 250-600 deg.C into a primary or sec. amine which is in the liq. or molten state or in an inert diluent and then isolating (I) from the mixt.
