摘要:A novel metal-organic framework (MOF) templated process for the synthesis of highly porous inorganic sorbents for removing radionuclides, actinides, and heavy metals is disclosed. The highly porous nature of the MOFs leads to highly porous inorganic sorbents (such as oxides, phosphates, sulfides, etc) with accessible surface binding sites that are suitable for removing radionuclides from high level nuclear wastes, extracting uranium from acid mine drainage and seawater, and sequestering heavy metals from waste streams. In some cases, MOFs can be directly used for removing these metal ions as MOFs are converted to highly porous inorganic sorbents in situ.

摘要:The present invention relates to the synthesis of a hydrazone β-keto ester by the reaction of an alkyl diazoester with a hydrazone aldehyde in the presence of a Lewis acid In a preferred embodiment, the hydrazone β-keto ester is then converted into a pyridazinone compound by the reaction with an alkyl acid chloride in the presence of a base, followed by acidification. A process for the production of a hydrazone aldehyde, which comprises contacting a hydrazine and glyoxal, is also described.

权利人:LITTLE INC A
摘要:Apparatus for the melt synthesis of inorganic compounds from elemental reactants, at least one of which is highly volatile at the temperature of the reaction. An enclosure means defining a reaction chamber and a reservoir-closure means containing the volatile elemental reactant form the reaction vessel which is sealed by a combination mechanical-liquid seal which is of a character to permit diffusion by high-pressure gas through it. Heating means are provided to effect at least three heating regimes: (I) liquefaction of a liquid sealant, (II) formation and maintenance of a molten reaction mass, and (III) heating of the volatile elemental reactant to vaporize it.

摘要:The present invention relates to the synthesis of a hydrazone β-keto ester by the reaction of an alkyl diazo ester with a hydrazone aldehyde in the presence of a Lewis acid. In a preferred embodiment, the hydrazone β-keto ester is then converted into a pyridazinone compound by the reaction with an alkyl acid chloride in the presence of a base, followed by acidification. The present invention also relates to a continuous process for the production of a hydrazone aldehyde comprising contacting a hydrazine and glyoxal, wherein the hydrazine and the glyoxal are added simultaneously to a reactor at a controlled rate.

摘要:The present invention generally relates to a process for the synthesis of selectively alkylated cyclodextrins. More particularly, the present invention relates to a process of cyclodextrin alkylation in a selective manner yielding hexakis(2,6-di-O-alkyl)-alpha-cyclodextrin, heptakis(2,6-di-O-alkyl)-beta-cyclodextrin and octakis(2,6-di-O-alkyl)-gamma-cyclodextrin.
