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:A simple one pot sol-gel method for the synthesis of bi-metal nanostructures is based on non-noble metals (Fe, Co and Sn) and titanium. The method involves the synthesis of mixed metal nanoscale composites using low cost precursors which allow for the synthesis of desired nanocomposite materials with self-scarifying titanium or silica supports. The procedure does not require any surfactant or any need for pH controlled step. Applicants' method involves the in-situ generation of precursors and their simultaneous entrapment in a gel. This simple one pot synthesis allows for the synthesis of homogenous size, shape and distribution of targeted nanostructures. Further, this method can be applied for the preparation of various nanocomposite materials using different choices of metals and self-scarifying supports. Applicants also show that Pd, the noble metal based nanocomposite is feasible.

摘要:The invention relates to a method for synthesis of aliphatic isocyanates from aromatic isocyanates in substantially 3 stages. In particular, the invention relates to a method for synthesis of bis{4-isocyanatocyclohexyl}methane (H 12 MDI) from bis{4-isocyanatophenyl}methane (MDI). More especially, the invention relates to a method for synthesis of H 12 MDI with a trans-trans isomer content of <30%, preferably of <20%, particularly preferably of 5 to 15%.

摘要:The present invention relates to a process for microwave assisted synthesis of N-methyl pyrrolidone (NMP). Particularly the process relates to the synthesis of N-methyl succinimide or corresponding analogs by using microwave irradiation which on hydrogenation in the presence of a hydrogenating catalyst gives N-methyl pyrrolidone. Compared to the conventional heating microwave process requires less energy inputs and reduces the reaction time drastically from 5-6 h to 2-5 min.

摘要:This invention is related to a preparation method of a supported catalyst Mo—O—K-Me x O y for the synthesis of methanethiol from H 2 S-containing syngas. The catalyst comprises of an active component of Mo—O—K-based species, an active promoter and a support denoted as metal (or metals)-carrier. The support is prepared by electroless plating method in such a way that the metal or metals chosen are plated onto the surface of the carrier. Transition metal, especially Fe, Co or Ni are selected to be the plating metal, while SiO 2 , Al 2 O 3 or TiO 2 are selected to be carrier. The catalyst thus prepared is found to be efficient for the synthesis of methanethiol from H 2 S-containing syngasor carbon oxides/hydrogen mixtures, especially regarding a minor formation of the by-product CO 2 .
