    摘要: The invention is a process for epoxidizing an olefin with hydrogen and oxygen in the presence of a catalyst comprising a noble metal and a titanium or vanadium zeolite in a solvent mixture comprising water, methanol, and a C3–C6 aliphatic ketone. This process surprisingly gives significantly reduced by-product glycol and glycol ethers formed by the unwanted ring-opening of epoxides.

    摘要: Disclosed is an improved process for the preparation of carbamates by heating an organic carbonate and an aromatic urea or polyurea in the presence of aluminum as catalyst and a promoter comprising a combination of iodine and a mercury salt.High reaction temperatures are avoided by the process and conversions to carbamate products are high. Additionally, the process is economically attractive because even the common aluminum foil can be used as the catalyst.The products prepared by the process can be used in the production of insecticides, and, particularly, as intermediates in the preparation of organic mono- and polyisocyanates.

    摘要: Allyl carbamates are disclosed. The allyl carbamates are prepared by reacting an isocyanate with an allylic alcohol or alkoxylated allylic alcohol. Suitable isocyanates are selected from hexamethylene diisocyanate (HDI), HDI biuret, dimer, HDI trimer, HDI allophanate, isophorone diisocyanate (IPDI), IPDI trimer, IPDI allophanate, bis(isocyanatocyclohexyl)methane, and mixtures thereof. The allyl carbamates have at least two allyl functional groups per molecule. UV-curable and air-drying coatings formulated from the allyl carbamates show excellent chemical resistance and physical properties.
