权利人:SHOWA DENKO KK
摘要:A technique to synthesize complex oxide ceramic powders which offers advantages of both the coprecipitation and sol-gel routes while doing away with the disadvantages is disclosed. Namely, the ability to achieve chemical homogeneity and crystallite size on the namometer length scale at a nonprohibitive cost is provided by the disclosed method. In one embodiment of the invention, a method for the synthesis of a mixed metal oxide powder is provided including (a) combining a liquid absorbent resin with at least one solution selected from the group consisting of solutions containing at least one organo-metallic compound and solutions containing at least one metallic salt compound, such that at least two metals are present in the liquid absorbent resin after the combining is completed; (b) after the combining, allowing the liquid absorbent resin to swell and gel and thereby form a swollen gel; (c) preparing a precursor material by changing at least one of the pH and temperature of the swollen gel; (d) pyrolyzing the precursor material to form a pyrolyzed precursor material; and (e) calcining the pyrolyzed precursor material to form a mixed metal oxide powder.

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:Preparation of azo pigments with low pcb content by coupling in the presence of olefins
发明人：RIEPER WOLFGANG
权利人:HOECHST AG
摘要:The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls. n According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR 1 , --CONHR 2 or --NR 3 COR 4 ) n in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.
