摘要:将二氮 (N 2 )工业还原为氨是一个能源密集型过程,消耗了全球能源供应的很大一部分.因此,几十年来一直在寻找能够在温和条件下结合 N 2并切割其强 N-N 键的物种.直到最近,已知支持 N 2固定和功能化的唯一物种是基于元素周期表中s和d区的少数金属.在这里,我们展示了 N 2的一锅结合,裂解和还原由主族物种转化为铵.该反应--一个复杂的多重还原-质子化序列--在室温下通过使用固相还原剂和酸试剂在单个合成步骤中进行.混合物的简单酸猝灭然后提供铵,存在于肥料中的氨的质子化形式.阐明了该过程中的基本反应步骤,包括关键的 N-N 键断裂过程,并分离了反应的所有中间体.

摘要:A mixed-bed catalytic system and its activation for direct synthesis of dimethyl ether from synthesis gas are described, comprising a catalyst for methanol synthesis and the zeolite ferrierite in its acid form as the methanol dehydrating component, the two being mixed physically in the form of powder of defined granulometry or as pellets. Another object of the present invention is a process for production of the acid form of the zeolite ferrierite. Another object of the present invention is a process for direct synthesis of dimethyl ether from a synthesis gas, using the catalytic system of the present invention.

摘要:Provided is a process for recycling waste residue from the synthesis of hexachlorocyclotriphosphazene. The process comprises: reacting waste residue separated out after a synthesis reaction of hexachlorocyclotriphosphazene is finished with an ammonia source, the ammonia source being liquid ammonia, ammonia gas, ammonia water, ammonium bicarbonate, ammonium carbonate or a combination thereof; adjusting the pH value at an end point to 6-10; subjecting the obtained reaction product to solid-liquid separation so as to obtain a filtrate and a filter cake; subjecting the filter cake to post-treatment so as to obtain a recovered metal chloride catalyst; extracting the filtrate by using chlorobenzene, i.e. an extracting agent, so as to obtain an extract phase and a raffinate phase; rectifying the extract phase to obtain chlorobenzene and recovered pyridine or pyridine derivatives; and dehydrating the raffinate phase to obtain recovered ammonium chloride. By means of the process, high-degree recycling and regeneration of waste residue from the synthesis of hexachlorocyclotriphosphazene are achieved, the recovery rate of pyridine or pyridine derivatives from the waste residue can reach 95-99% or higher, the recovery rate of ammonium chloride and the metal chloride catalyst can reach 98% or higher, and no new waste residue is generated throughout the whole process.

权利人:ZHANJIANG GIANT SUCCESS INVEST CO LTD
摘要:A method for synthesis of porous inorganic materials, preparation of a catalyst and catalytic cracking of petroleum hydrocarbons thereof includes processes for synthesis of porous inorganic materials and preparation of the catalytic cracking catalyst and catalytic cracking of petroleum hydrocarbons. The synthesis process is advantaged in low cost in raw materials; the porous inorganic material has various pore structures; and transitional metal used overcomes the defects of the catalytic properties. The porous inorganic material serving as the main active ingredient and containing crystalline aluminum silicate zeolite structures provides surface acidity required by the catalytic reaction. The surface acidity is flexibly adjusted. The hierarchical pore profile improves the accessibility of the active center of the zeolite structure and favors the reaction efficiency and benefits of the petroleum hydrocarbon cracking, and reduces the negative effects caused by diffusion limit. The catalyst containing the porous inorganic material has low manufacturing cost and better properties.

权利人:IDEC PHARMA CORP
摘要:The present invention provides a process for high yield regioselective synthesis of DTPA derivatives that eliminates the need for ion exchange chromotographic separation of intermediates. Moreover, as this process yields a single regioisomer of the chelate, it provides for the regiospecific synthesis of desired chelates useful as radiolabeling agents.
