摘要:The present invention provides a catalyst substance that is stable and performs well in the synthesis of ammonia, one of the most important chemical substances for fertilizer ingredients and the like. The catalyst substance exhibits catalytic activity under mild synthesis conditions not requiring high pressure, and is also advantageous from a resource perspective. Further provided is a method for producing the same. This catalyst comprises a supported metal catalyst that is supported on a mayenite type compound including conduction electrons of 10 15 cm −3 or more and serving as a support for the ammonia synthesis catalyst. The mayenite type compound used as the support may take any form, including that of powder, a porous material, a sintered body, a thin-film, or a single crystal. Use of this catalyst makes it possible to increase the electron donating ability toward a transition metal.

摘要:A method for producing a compound of formula (I) or a pharmaceutically acceptable salt, solvate, tautomer or stereoisomer, such as compound 1 and compound 2 is disclosed. The method proceeds through an O-allylated tyrosine-based compound, such as compound 3 and preferably comprises [3,3] sigmatropic Claisen rearrangement and olefin cross metathesis reactions. In addition, a pharmaceutical composition comprising a compound of formula (I) a tumor necrosis factor (TNF) related apoptosis inducing ligand (TRAIL) and a pharmaceutically acceptable carrier or excipient is disclosed.

摘要:Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al 2 O 3 having a specific surface area of 5 m 2 /g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al 2 O 3 ; and a third step for performing a reduction process on the 12CaO·7Al 2 O 3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.
