Abstract: The present invention provides methods of forming dialkyl carbonate wherein catalyst buildup in the reaction equipment, the separation equipment, and transfer lines there between is reduced and even eliminated. In one embodiment, the method includes introducing alkanol, carbon monoxide, oxygen, and a catalyst to a reactor having a gaseous head space and a liquid body space. The reactor is operated under conditions to form dialkyl carbonate and water. A product stream containing dialkyl carbonate, water, and residual reactants is removed from the head space of the reactor and introduced to a cyclone with a flushing stream. A liquid bottom stream is captured from the cyclone and introduced to the reactor. The gaseous top stream contains product dialkyl carbonate.

Abstract: Hardenable and hardened dental compositions that include radiation-to-heat converters, and articles including such hardenable and hardened compositions, are provided. Upon irradiating, the hardened compositions increase in temperature, which can be useful for reducing the bond strengths of orthodontic appliances adhered to tooth structures with the hardened compositions.

Abstract: A method for joining sections of coated pipe comprises providing two sections of metal pipe, each section of metal pipe having at least a first polymeric coating on its outer surface. The first polymeric coating comprises a first polymer coating selected from the group consisting of a first epoxy/olefin interpenetrating polymer network (IPN) layer, a thermoplastic layer, and a thermosetting layer. The sections of metal pipe are aligned end-to-end and bonded together to form a desired closure. A second polymeric coating comprising a layer of epoxy/olefin semi- or full-IPN is applied to the closure and to any desired additional area of coated pipe to form a seam and to secure the joint. A method for patching a damaged coated pipe using a patch comprising a polyolefin/epoxy semi-or full IPN is also disclosed.
