Disclosed is a method for forming enals from corresponding alehydes in a single enclosed unit such as a divided wall reaction distillation unit. The method of the present invention includes (a) feeding an aldehyde feed stream comprising at least one aldehyde reactant into a reaction zone contained within said single enclosed unit; (b) reacting said at least one aldehyde reactant in said reaction zone in the presence of a catalyst to form an enal-containing reaction zone effluent comprising an enal; (c) purifying said enal-containing reaction zone effluent in a first separation zone within said single enclosed unit to form an enal-rich product mixture and a residual unreacted aldehyde mixture; and (d) collecting from said single enclosed unit at least a portion of said enal-rich product mixture. The method of the present invention results in high enal yields at a markedly reduced capital cost and energy consumption as compared to prior art processes.

Disclosed are a catalyst composition containing a phosphorous-based ligand and a hydroformylation process using the same. More specifically, disclosed are a catalyst composition containing a monodentate phosphite ligand, a monodentate phosphine ligand and a transition metal catalyst, wherein the total content of the entire ligand including the monodentate phosphite ligand and the monodentate phosphine ligand is 1 to 33 moles, based on 1 mole of the transition metal catalyst, and a hydroformylation method using the same. The present invention has an effect of providing a catalyst composition which reduces an N/I (ratio of normal to iso) selectivity of aldehydes produced by hydroformylation of an olefin-based compound and exhibits superior catalytic activity and stability, and a hydroformylation method of an olefin-based compound using the catalyst composition.

The present invention relates to a plant for performance of heterogeneously catalyzed gas phase reactions. The plant entails a reactor, at least one line leading into the reactor for introduction of reactants into the reactor, at least one first feed for providing at least one first reactant A, which leads into the line, at least one second feed for providing at least one second reactant B, which leads into the line, at least one third feed for providing a cycle gas G, which leads into the line, a temperature control unit which is disposed in the line upstream of the reactor and is for controlling the temperature of the first reactant A and/or second reactant B and/or cycle gas G prior to entry into the reactor and at least one outlet for products, by-products and/or unreacted reactants from the gas phase reaction.
