    摘要: A process for producing a 1,3-diol, e.g., 1,3-propanediol, and/or a 3-hydroxyaldehyde, e.g., 3-hydroxypropionaldehyde, is disclosed which comprises contacting a combination of an epoxide, carbon monoxide and hydrogen in the presence of a rhodium-containing.catalyst composition effective to promote the hydroformylation of the epoxide at conditions effective to form at least one of a 1,3-diol and a 3-hydroxyaldehyde. The rhodium-containing catalyst composition comprises an anionic rhodium-containing complex. A promoter component is preferably provided to enhance at least one of the rate and selectivity of the epoxide hydroformylation reaction. Rhodium-containing compositions and a processes for producing rhodium-containing compositions are also disclosed.

    摘要: A process for producing a 1,3-diol, e.g., 1,3-propanediol, or a 3-hydroxyaldehyde is disclosed which comprises contacting a combination of an epoxide, carbon monoxide and hydrogen in the present of a rhodium-containing catalyst effective to promote the hydroformylation of the epoxide at conditions effective to form at least one of a 1,3-diol and a 3-hydroxyaldehyde, the contacting occurring in the substantial absence of a promoting amount of alkali metal ions, and at least a portion of the rhodium-containing catalyst being formed substantially without incorporation of the epoxide. A process for producing such rhodium-containing compositions is also disclosed.

    摘要: The invention relates to a process for preparing cyclic polyethers from cyclic alkylene carbonates in the presence of a solvent, wherein the process is carried out in the presence of a solvent selected from the group containing a carbonyl moiety, nitrile moiety or mixture thereof. In addition, ionic catalysts may be employed to increase the selectivity to cyclic polyether.
