    摘要： Realized is a method for restoring the activity of a catalyst for producing a carbonate ester by a simple technique with no use of a complicated step such as calcining or the like to allow the catalyst to be reusable, and a method for producing a carbonate ester at a high yield by use of the catalyst thus regenerated. The above-described problem has been solved by a method for regenerating a catalyst containing CeO 2 , the catalyst being usable for a carbonate ester generation reaction of generating a carbonate ester from carbon dioxide and an alcohol, the method comprising (a) a separation step of separating the catalyst as a crude catalyst from a reaction solution of carbon dioxide and the alcohol; and (b) a catalyst processing step of washing the crude catalyst with a washing alcohol to provide a purified catalyst.

    摘要： An alkylene carbonate is produced by the reaction of an alkylene oxide with carbon dioxide in the presence of a phosphonium catalyst in a process in which (a) the alkylene oxide, carbon dioxide and the phosphonium catalyst are continuously introduced into a reaction zone from which a product stream containing alkylene carbonate and used phosphonium catalyst is withdrawn, (b) alkylene carbonate and a stream containing used phosphonium catalyst are separated from the product stream, (c) the alkylene carbonate, separated in step (b), is recovered as product, (d) at least a part of the stream containing used phosphonium catalyst is subjected to purification, to obtain purified phosphonium catalyst, and (e) purified phosphonium catalyst is recycled to the reaction zone, optionally in combination with another part of the stream containing used phosphonium catalyst.

    摘要： A process for the production of alkyltin alkoxides which comprises subjecting at least one alkyltin compound selected from among organotin compounds having tin-oxygen-tin linkages as the starting compound and a hydroxyl compound as the reactant to dehydration to obtain an alkyltin alkoxide corresponding to the starting compound and the reactant, characterized by continuously feeding the starting compound and the reactant into a reactor, discharging a water-containing low boiling point component from the reactor, and continuously withdrawing a reaction fluid containing an alkyltin alkoxide as the bottom from the reactor.
