Abstract: Catalysts for the epoxidation of alkene, especially ethylene, to the corresponding alkylene oxide, e.g., ethylene oxide, which catalysts contain a high silver content on carriers having a high surface area and a high pore volume are disclosed. Methods for making and using such catalysts are also disclosed.

Abstract: A method is disclosed for separating impurity components, UV absorbers and/or UV absorber precursors contained in an ethylene glycol-water stream thereby desirably allowing the recovery of the glycols contained in such stream in an economical and efficient manner. Specifically, these undesirable components are separated by contacting the ethylene glycol-water stream with a suitable semi-permeable membrane to effect such separation.

Abstract: A water-blown, polyurethane foam modified by incorporation of specific zeolites at levels of from about 0.5 to ten parts per hundred parts polyol exhibit superior combustibility with no halogen or phosphorus flame retardant additive in the foam. Conventional halogen/phosphorus flame retardants, while providing a level of combustion resistance, generally lead to increased smoke containing noxious, and potentially toxic, combustion products.

Abstract: A process for making low density and optionally low resilience, soft, flexible polyurethane slabstock foam having a substantially open cell structure without crushing, without requiring auxiliary inert blowing agents, by reacting under a condition which permits the foam to rise freely, a conventional hydroxyl-containing polyether polyol with a polyisocyanate at an isocyanate index of between about 60 and 95 in the presence of a foam processing aid comprising a low equivalent weight crosslinking agent and/or extending agent and, as needed, a cell opening agent.

Abstract: This invention relates to vicinal di(hetero)alkylene organometalate compounds comprising one or more metal oxides in association with an alkanolamine, an alkyleneamine, an alkylene glycol or mixtures thereof. This invention also relates to an alkyleneamines producers composition rich in triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA), and to processes for the preparation thereof using the vicinal di(hetero)alkylene organometalates.
