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.

权利人:COVESTRO DEUTSCHLAND AG
摘要:The present invention relates to a process for preparing a polyester carbonate on the basis of cycloaliphatic diacids and at least one 1,4:3,6-dianhydrohexitol and at least one additional aliphatic dihydroxy compound, to the polyester carbonate prepared according to the process and to a molding compound and a molding body containing the polyester carbonate. The process according to the invention is a direct synthesis, in which all structural elements forming the subsequent polyester carbonate are present as monomers already in the first process step. It is characterized in that a specific ratio of 1,4:3,6-dianhydrohexitol and the at least one additional aliphatic dihydroxy compound is advantageous.

发明人：KNIFTON JOHN F
权利人:TEXACO DEVELOPMENT CORP
摘要:This invention concerns the improved preparation of glycol esters, such as ethylene glycol diesters, by reaction of carbon monoxide and hydrogen in the presence of a ruthenium or osmium-containing catalyst and a liquid phase medium containing a carboxylic acid co-reactant. The improvement which comprises the invention here also involves use of a co-catalyst species selected from the group consisting of one or more alkali metal salts, alkaline earth metal salts, quaternary ammonium salts, iminium salts and quaternary aliphatic phosphonium salts.
