    • Polyalcohols are produced by a process comprising hydrogenating polyketones, which are copolymers of carbon monoxide and at least one olefin, in the presence of a catalyst and a solvent. The catalyst is prepared from a ruthenium-containing compound and a trialkylphosphine. The trialkylphosphine is represented by the general formula (I):R.sup.1 R.sup.2 R.sup.3 P (I)wherein R.sup.1, R.sup.2, and R.sup.3 each represent an alkyl group having 1 to 12 carbon groups. The carbon groups may be substituted. The process requires minimal amounts of the catalyst, and the polyalcohols produced by this method have a high hydroxyl group content.
    • 多元醇通过在催化剂和溶剂的存在下氢化作为一氧化碳和至少一种烯烃的共聚物的聚酮的方法制备。 催化剂由含钌化合物和三烷基膦制备。 三烷基膦由通式(I)表示:R 1 R 2 R 3 P(I)其中R 1,R 2和R 3各自表示具有1至12个碳基团的烷基。 碳基团可以被取代。 该方法需要最少量的催化剂,并且通过该方法制备的多元醇具有高羟基含量。
