    • A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises:(I) forming a reaction mixture comprising:(a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with:(i) a triorganophosphine, and(ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution and said electron withdrawing group being substantially non-reactive in said process;(b) an alpha-olefin having 2 to 5 carbon atoms,(c) carbon monixide, and(d) hydrogenwith the proviso that the reaction mixture has mole ratio of said carbxoylic acid to rhodium of at least about 2; and(II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.

    • Novel polymethylol polyphosphonates are prepared by reacting a trisubstituted polyphosphite having at least one alkyl group and formaldehyde. The phosphite reactant may contain the requisite hydroxyl functionality [e.g. - heptakis (dipropylene glycol) triphosphite] or the hydroxyl functionality may be introduced by carrying out the reaction in the presence of a polyol, e.g. - glycerol, as a protic solvent. The resulting reaction product is a water-soluble liquid of relatively low viscosity and may be employed without any refining. The thus-formed polyphosphonates can be readily incorporated into either rigid urethane foam formulations to impart flame retardancy or phenolic resins to improve flexibility.
    • 通过使具有至少一个烷基的三取代多亚磷酸酯和甲醛反应来制备新的多羟甲基多聚膦酸酯。 亚磷酸酯反应物可含有必需的羟基官能团[例如 - 七(二丙二醇)三亚磷酸酯]或羟基官能团可以通过在多元醇的存在下进行反应来引入。 - 甘油,作为质子溶剂。 所得反应产物是相对低粘度的水溶性液体,可以不经任何精制而使用。 如此形成的聚膦酸盐可以容易地并入刚性聚氨酯泡沫制剂中以赋予阻燃性或酚醛树脂以改善柔韧性。
