标 题:Direct synthesis of organic polymer-inorganic oxide composites
发明人：TAYLOR LYNN JOHNSTON
权利人:TAYLOR LYNN JOHNSTON
摘要:There is disclosed an in situ process for the preparation of a composite material consisting essentially of an organic polymer or copolymer having dispersed therein an inorganic oxide or mixture of oxides, said process comprising the simultaneous or sequential synthesis of the organic polymer from at least one non-polymeric organic precursor and of the inorganic oxide or oxide mixture derived from at least one inorganic-oxide precursor.

标 题:Process for the synthesis of alpha-methylene-gamma-butyrolactone
发明人：TADEN ANDREAS; BECK HORST; MYRTOLLARI KAMELA; KOURIST ROBERT; NIGL ANDREA
权利人:HENKEL AG & CO KGAA
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.

标题:Synthesis of plate-like sapo-34 crystals
发明人：FICKEL DUSTIN; KULKARNI NEETA
权利人:SABIC GLOBAL TECHNOLOGIES BV
摘要:Disclosed is a SAPO-34 molecular sieve having platelet morphology with the smallest dimension on the order of a few nanometers. Also disclosed are methods and systems of using said molecular sieve for catalyzing the reaction of alkyl halides to light olefins. These methods and systems have been shown to have maximum combined selectivity of ethylene and propylene of at least 90% or ranging from 90% to 98%.
