    摘要: Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.

    摘要: The present invention provides an alkylene-carbonate synthesis catalyst comprising a compound insoluble to one phase containing alkylene carbonate produced when the alkylene oxide and carbon dioxide are reacted with the catalyst and soluble to the other phase substantially free of alkylene carbonate. The catalyst allows alkylene carbonate to be produced with high yield and selectivity and be readily collected. The catalyst also facilitates repeated or continuous reaction process in a cost-effective manner. The present invention also provides an apparatus for producing alkylene carbonate using the catalyst.

    摘要: An ion resonance condition is corrected accurately in an ion trapping device. Measurements are repeated by alternately applying and not applying a resonance frequency voltage while spectral data is obtained continuously. Data obtained in the absence of the resonance frequency voltage is used as reference data to correct the set data of a resonance condition. As a result, calibration can be made while taking into consideration the variations in the amount of ions that are introduced into the ion trap.
