    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: Ethylene oxide (EO) adducts of di- ard tri-functional starters, such as, trimethylolpropane and glycerine, provide unexpected improvements in the "wet compression set" properties of high resilience (HR) urethane foams. Heretofore, wet set improvements have been achieved through the use of EO adducts of tetrols because of the high degree of crosslink density which these materials impart to a urethane polymeric composition. One commercial wet set additive, which is an EO adduct of pentaerythritol and diglycerine, is an effective wet set improver. Surprisingly, EO adducts of di- and tri-functional starters provide improvements in foam wet set properties, which are comparable to those obtained with such commercial wet set additive. Specifically, EO adducts of glycerine in the 500 to 10,000 molecular weight range yield foam wet set improvements equal to those of such commercial wet set additive at as low as 20 percent of the use level on an equivalent weight basis. Moreover, the EO adducts of glycerine yield foams having improved elongation properties and improved processing (stability) characteristics as compared to those observed with such commercial wet set additives. An EO adduct of glycerine having a number average MW of 1,000 is particularly useful in the invention.
