摘要:The Partial Hydrolysis Of A Mixture Of Molybdenum And Tantalum Methoxides (Mo:Ta = 1:2) With Stoichiometric Amounts Of Water Yields A New Bimetallic Complex Mo2Ta4O8(Ome)(16) (I) On Crystallization From Toluene. The Molecules Of I Appear To Be A Combination Of Two Moo2((Opr)-Pr-I)(2) Units With The Earlier Described Ta4O4((Opr)-Pr-I)(12) Core. The Thermal Reduction Of A Mixture Of Moo((Opr)-Pr-I)(4) And Ta-2((Opr)-Pr-I)(10) (In A 1:1 Mo:Ta Ratio) Followed By Oxidation Of The Products By Dry Oxygen,Provides Access To Mo4Ta4O16((Opr)-Pr-I)(12) (II). The Same Procedure,Using Limo2O4((Opr)-Pr-I)(4)(oc2H4Ome) Instead Of Moo((Opr)-Pr-I)(4),Yielded Trimetallic Limo4Ta3O14((Opr)-Pr-I)(9)(oc2H4Ome)(3) (Iii) In Minor Yields. The Molecular Structure Of Ii Can Be Described As A Distorted Cube,The Corners Of Which Are occupied In Turn By [((Pro)-Pr-I)(3)Ta(Mu-O)(3)] octahedra And [moo(Mu-O)(3)] Tetrahedra Sharing Common Vertexes. The Molecular Structure Of Iii Can Be Derived From That Of Ii By Replacing One [(Ipro)(3)Ta(Mu-O)(3)] octahedron With An [li(Mu,Eta(2)-oc2H4Ome)(3)] Trigonal Prism (The Coordination Number Of The Three Mo Atoms Is Then Increased To Six).

摘要:The present invention relates to a production method of sol-gel ( 100 ) comprising tantalum metal and a method ( 200 ) concerning use of the sol-gel produced for enrichment of phosphopeptides by means of a microextraction syringe. The syringe which is filled with the sol-gel comprising tantalum metal enables to make analysis of natural samples, that comprise low amount of phosphoprotein, with high precision and in a very short time and it shows compliance with mass spectrometric techniques. Thus, it can be used for application of fast and practical analytical methods for the analysis made in phosphoproteomics studies wherein mass spectrometric techniques are used.

摘要:The present invention addresses the problem of providing a bonded body which has a high airtightness and exhibits excellent durability under high-temperature and high-pressure conditions. This problem is solved by a bonded body in which a complex of a zeolite and an inorganic porous support, and a dense member are bonded together by an inorganic glass or an inorganic adhesive. The inorganic glass or the inorganic adhesive has a thermal expansion coefficient of 30×10−7/K to 90×10−7/K, and the inorganic glass has a softening point of 550° C. or lower. The present invention also addresses the problem of providing a method of efficiently producing an alcohol by installing a separation membrane in an alcohol synthesis reactor based on a bonding method that gives good sealing performance and durability under high-temperature and high-pressure conditions and in the presence of methanol vapor. This problem can be solved by an alcohol production method of obtaining an alcohol by allowing a raw material gas, which contains at least hydrogen and carbon monoxide and/or carbon dioxide, to react in the presence of a catalyst in a reactor. In the reactor for carrying out the reaction, an alcohol-selective permeable membrane bonded with a dense member is installed, and an alcohol generated by the reaction permeates and is recovered through the selective permeable membrane.
