    Abstract: A method for hydrogenation of a conjugated diene polymer is provided. The conjugated diene polymer in an inert organic solvent is brought into contact with hydrogen in the presence of a hydrogenation catalyst composition to selectively hydrogenate the unsaturated double bonds in the conjugated diene units of the conjugated diene polymer. The hydrogenation catalyst composition includes: (a) a titanium compound; (b) a compound represented by formula (II) or formula (III): wherein R is C1-C12 alkyl, C3-C12 cycloalkyl, aryl or alkyl aryl, M is C1-C12 alkyl, C1-C12 alkoxy, aryl, alkyl aryl, phenoxy or hydroxyl, and n=1˜3; and (c) a alkylaluminum compound.

    Abstract: Ruthenium-cobalt- or cobalt-containing catalysts which have been promoted with phosphonites or phosphinites effectively catalyze the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers. Methylal, for example, may be reacted with syngas, i.e., CO and H.sub.2, in the presence of these phosphonite- or phosphinite-promoted cobalt or ruthenium- cobalt catalysts to form the monomethyl ether of ethylene glycol. In a like manner acetaldehyde may be converted to the corresponding propylene glycol monoether. The process may advantageously be carried out with high yields and selectivities in the presence of a polar or non-polar organic solvent in combination with the catalyst system of this invention.The invention is also directed to the phosphonite- or phosphonite-promoted cobalt and ruthenium-cobalt catalyst system per se.
