摘要： Large crystals of titanium silicalite or intergrowths of intergrown smaller crystals, having a mean particle size greater than 2 μm, have been found catalytically effective at commercially reasonable rates for the epoxidation of olefins in the presence of hydrogen peroxide. Crystals synthesized with a silica source having a low sodium content exhibit high levels of production and selectivity. The crystals have a low attrition rate and are easily filterable from a product stream.

摘要： An improved process for making allylic/ethylenic copolymers is disclosed. Increasing the reaction temperature during addition of the ethylenic monomer/initiator mixture results in a substantial increase in the polymer yield obtained compared with the yield from a conventional process in which a constant temperature is used. Copolymers made by the process include valuable coating resins such as styrene-allyl alcohol and hydroxy-functional acrylic copolymers.

摘要： Propylene is converted to propylene oxide in a highly efficient liquid phase process wherein temperature and pressure are both increased over the course of the epoxidation, which is preferably conducted in a continuous mode of operation. The catalyst used is a heterogeneous catalyst such as titanium silicalite or titania-on-silica. The oxidizing agent is an active oxygen species such as hydrogen peroxide or an organic hydroperoxide. When the desired yield of propylene oxide can no longer be maintained, the catalyst is replaced or regenerated. Regeneration by washing the catalyst with a hot solvent containing a source of ammonium or alkali metal cations is highly effective, especially where the catalyst is a titanium-containing zeolite.

摘要： Dispersion polyols which are liquid--liquid dispersions containing a first polyol having a substantially polyoxypropylene internal block having an equivalent weight in excess of about 700 Da and a high oxyethylene-content external block, and a second polyol which is a substantially polyoxyethylene polyol containing minimally 50 weight percent oxyethylene moieties. The dispersion polyols are stable and exhibit broad processing latitude when preparing hypersoft polyurethane foams. The dispersion polyols are advantageously prepared in situ, preferably in the presence of a double metal cyanide oxyalkylation catalyst.
