    Abstract: A process for simultaneously producing a 2-(2-aminoalkoxy)alkanol compound and a morpholine compound is disclosed wherein an oxydialkanol is contacted with ammonia in the presence of a catalytically effective amount of a hydrogenation/dehydrogenation catalyst at a temperature of from about 190.degree. C. to about 230.degree. C. and at a pressure ranging from about 700 psig to about 2200 psig, said oxydialkanol having the formula: ##STR1## wherein each R is, independently, a hydrogen or a lower alkyl radical; and recovering said 2-(2-aminoalkoxy)alkanol compound and said morpholine compound from the resulting reaction mixture.

    Abstract: Secondary isopropylamine terminated polyoxyethylene and/or polyoxypropylene diamines or triamines are formed in a one-step reaction when a polyoxyethylene and/or polyoxypropylene primary diamine or triamine is hydrogenated with hydrogen in the presence of a hydrogenation catalyst, hydrogen and acetone. The secondary isopropylamine terminated polyoxyethylene and/or polyoxypropylene primary diamines or triamines are useful as curing agents for epoxy resins.

    Abstract: Disclosed is an improvement in a process for production of cyclohexane by liquid phase hydrogenation of benzene wherein no diluent is necessary, which comprises contacting benzene and hydrogen in the presence of a mixed catalyst bed comprising a first catalyst which is a less active hydrogenation catalyst selected from elements of Group VIII of the Periodic Table and a second, more active catalyst, comprising a Group VIII metal supported on an oxide, such as, for example, alumina, silica or titania at a temperature of about 40.degree. C. to about 300.degree. C. and pressure sufficient to keep the benzene liquid at the chosen reaction temperature.
