    摘要： 1,3-propanediol is prepared in a process comprising the steps of:contacting ethylene oxide with carbon monoxide and hydrogen in an essentially non-water-miscible solvent in the presence of an effective amount of a non-phosphine-ligated cobalt catalyst and an effective amount of a lipophilic quaternary ammonium salt at a temperature within the range of about 50.degree. to about 100.degree. C. and a, pressure within the range of about 500 to about 5000 psig, under reaction conditions effective to produce an intermediate product mixture comprising less than 15 wt % 3-hydroxypropanal;adding an aqueous liquid to said intermediate product mixture and extracting into said aqueous liquid at a temperature less than about 100.degree. C. a major portion of the 3-hydroxypropanal so as to provide an aqueous phase comprising 3-hydroxypropanal in greater concentration than the-concentration of 3-hydroxypropanal in said intermediate product mixture and an organic phase comprising at least a portion of the cobalt catalyst or a cobalt-containing derivative thereof and at least a portion of the lipophilic quaternary ammonium salt;contacting the aqueous phase comprising 3-hydroxypropanal with hydrogen in, the presence of a hydrogenation catalyst at a pressure of at least about 100 psig and a temperature during at least a portion of the hydrogenation step of at least 40.degree. C. to provide a hydrogenation product mixture comprising 1,3-propanediol.

    摘要： This invention relates to a process for making 3-hydroxypropanal by intimately contacting(a) ethylene oxide,(b) ditertiary phosphine-modified cobalt carbonyl catalyst, said phosphine being a hydrocarbylene-bis(monophosphabicyclononane) in which each phosphorus atom is joined to hydrocarbylene and is a member of a bridge linkage without being a bridgehead atom and which hydrocarbylene-bis(monophosphabicyclononane) has 18 to 50 carbon atoms, 8 carbon atoms thereof together with a phosphorus atom being members of each of the two bicyclic skeletal structures,(c) a catalyst promoter comprising an acid and a metal salt promoter selected from a salt of a metal of Group IIA, Group IIB, Group IIIB and the Rare Earth Series of the Periodic Table of the Elements (CAS version),(d) carbon monoxide, and(e) hydrogen, the molar ratio of carbon monoxide to hydrogen being from about 4:1 to about 1:6,in liquid-phase solution in an inert reaction solvent, at a temperature of from about 30.degree. C. to about 150.degree. C. and a pressure of from about 50 psi to about 10,000 psi. The use of the acid/metal salt promoter enhances the activity of the catalyst.
