    摘要: Provided is a method for continuously producing a cyclic carbonate, by which generation of a glycol in a reaction for synthesizing a cyclic carbonate is suppressed, and a cyclic carbonate having a high purity can be efficiently obtained even by simple purification. A method for continuously producing a cyclic carbonate, including filling a catalyst in a fixed-bed tube reactor, and continuously feeding carbon dioxide and an epoxide to the fixed-bed tube reactor to thereby bringing the carbon dioxide and the epoxide into contact with the catalyst, while continuously withdrawing the reaction liquid in the fixed-bed tube reactor, wherein the method includes a pre-treatment step in which a pre-treatment liquid containing a cyclic carbonate is brought into contact with the catalyst before feeding the carbon dioxide and the epoxide to the fixed-bed tube reactor, and the generated glycol is removed out of the system.

    摘要: Provided are an apparatus and method for continuously producing a cyclic carbonate which are easily scaled up without requiring a large-sized reactor or excessive ancillary facilities even in the case of producing a cyclic carbonate by using an immobilized catalyst as a catalyst on an industrial scale, are able to produce a cyclic carbonate without impairing the expected catalytic efficiency and catalyst lifetime, are economical, and exhibit excellent industrial productivity. The apparatus includes an adiabatic reactor to be filled with a heterogeneous catalyst for reacting an epoxide with carbon dioxide, a circulation path for returning at least a portion of a fluid mixture in a liquid form flowed out through a reactor outlet into the reactor, a carbon dioxide supply means for continuously supplying carbon dioxide in a liquid form or a supercritical state into the circulation path, and an epoxide supply means for continuously supplying an epoxide in a liquid or solution form into the circulation path.

    摘要: A method for producing a hydrogenated petroleum resin by reacting dicyclopentadiene with a vinyl aromatic compound, subjecting the reaction product obtained by this reaction to thermal polymerization, and then hydrogenating the resulting product, including the following steps (A) to (C): (A) a preliminary reaction step of reacting a vinyl aromatic compound represented by the following Formula (1) (in the formula, R 1 is a hydrogen atom or the like) with dicyclopentadiene under the condition that selectivity for a phenylnorbornene derivative, which is a reaction product and is represented by the following Formula (2) {in the formula, R 1 has the same meaning as in the above Formula (1)}, is 90% or more to obtain a reaction liquid containing the phenylnorbornene derivative: (B) a polymerization step of heating the reaction liquid, which contains the phenylnorbornene derivative and is obtained in the preliminary reaction step (A), to a temperature of 240 to 300°C to polymerize the reaction liquid, thereby obtaining a polymerization reaction product; and (C) a hydrogenation step of hydrogenating the polymerization reaction product, which is obtained in the polymerization step (B), in the presence of a catalyst to obtain a hydrogenated petroleum resin.
