标 题 :Combinatorial synthesis of particulate materials
发明人：KODAS TOIVO T; HAMPDEN-SMITH MARK J
摘要:Methods for fabricating and analyzing particulates having a varying material property such that particulates having a selected desirable material property can be identified. The particulates can be analyzed to determine the particulates having the best properties for a particular application. The particulates can be metals, inorganic compounds, organic compounds and composites. The method of the present invention enables the rapid and economical fabrication and screening of a large number of different compositions.

摘要:The present application provides a process for the preparation of α-methylene-γ-butyrolactone, said process comprising the steps of:a) acetylating the C1-hydroxyl group of isoprenol to yield isoprenyl acetate;b) forming 4-acetoxy-2-methylene-butan-1-ol from said isoprenyl acetate by whole cell biotransformation, said step comprising:i) contacting a cell (CB) with a culture medium containing said isoprenyl acetate or with a culture medium contiguous with an organic phase containing said isoprenyl acetate under conditions that enable the cell to form 4-acetoxy-2-methylene-butan-1-ol from isoprenyl acetate; and,ii) optionally isolating the resultant 4-acetoxy-2-methylene-butan-1-ol, wherein said cell (CB) exhibits activity of at least one alkane monooxygenase enzyme which catalyzes the formation of 4-acetoxy-2-methylene-butan-1-ol from isoprenyl acetate;c) oxidizing said 4-acetoxy-2-methylene-butan-1-ol to yield 4-acetoxy-2-methylene butyric acid; and,d) converting said 4-acetoxy-2-methylene butyric acid to α-methylene-γ-butyrolactone by hydroxylysis to γ-hydroxy-α-methylenebutyric acid and subsequent cyclization of said γ-hydroxy-α-methylenebutyric acid.

摘要:The synthesis of fluoropolyarylene ether with a high degree of polymerization is enabled, by using a copper complex catalyst with an oxidation potential in the range of -1V to 2V, for the oxidative polymerization of fluorophenols that contain at least one hydrogen atom as well as a fluorine atom bonded to the carbon atoms constituting the benzene ring.
