摘要： A cracking process for a reaction distillation of chlorosilane slurry includes feeding a chlorosilane slurry into a phase separator, drying a solid phase, feeding a chlorosilane polymer into a plate distillation column, returning kettle materials of the plate distillation column, and dividing a material produced from a top of the column. The process adopts an ionic liquid catalyst, which is environmentally friendly and reusable. The cracking and distillation of chlorosilane polymer are carried out simultaneously to shorten the time and increase the utilization rate of raw materials, which can reduce energy consumption and save costs and facilitate industrial production. A plate column is used as a distillation column, in which the two phases of the gas and liquid are sufficiently contacted. Therefore, the transfer of mass and heat is good, the production capacity is good, and the tower is not easily blocked, thereby making it easy to clean.

摘要： The present application belongs to the field of life health, and discloses a sugar chain and a composition thereof, and use in the prevention and/or treatment of coronavirus infection. The sugar chain contains any one or more of Neu5Acα2-N1Gal building blocks, and/or any one or more of xFuc-N1Gal-N1(xFuc-N1)GlcNAc building blocks, at the non-reducing end, where, x=0 or 1, and N1=1, 2, 3, 4 or 6. A glycosidic bond formed between Neu5Ac and Gal is an α2 glycosidic bond. In the xFuc-N1Gal-N1(xFuc-N1)GlcNAc building blocks, a glycosidic bond formed between any two adjacent monosaccharides is an α1 or β1 glycosidic bond. The specific building block contained at the non-reducing end of the sugar chain blocks the binding of the virus to the host, thereby blocking virus invasion and infection of the respiratory tract/lung, and achieving the specific prevention and treatment.

摘要： The disclosure provides a device and method for extracting a clean liquid from a slurry reactor in an environment-friendly and energy-saving manner. The method mainly includes the following steps: S1. siphoning slurry in the slurry reactor into a material collecting pipe, and then spraying the slurry into a settling tank, so that solid particles settle in the settling tank and return to the slurry reactor through a discharging pipe; S2. making supernatant in the settling tank flow upward along a settling pipe, and then flow downward at a pipe intersection into a clear liquid pipe and flow into a clear liquid transition tank; S3. discharging liquid from the clear liquid transition tank in an overflow manner to keep the constant liquid level and a pressure required for siphoning; and S4. introducing gas in the material collecting pipe into an escape pipe and continuously discharging the gas to ensure that the liquid level in the escape pipe is always higher than the pipe intersection so as to ensure that the slurry reactor and the clear liquid transition tank are always communicated and the liquid levels are the same. The device according to the disclosure is simple in structure, and the process is simple, safe and reliable, and is not prone to failure. It is easy to implement large-scale continuous operation and adjust separation efficiency and precision. The device requires low equipment investment and is low in operation cost and environmentally friendly.

摘要： A method for extracting palladium includes: (1) mixing a palladium-containing material with nitric acid and an alkali metal ion-containing catalyst to obtain a mixed solution, heating the mixed solution, and removing a resulting residue to obtain a palladium-containing leaching liquor; and (2) subjecting the palladium-containing leaching liquor obtained in step (1) to separative extraction to obtain metallic palladium or at least one palladium-containing product, and reusing a residual solution for step (1) in a subsequent extraction. The alkali metal ion-containing catalyst of the present disclosure can leach palladium at a higher rate than that when pure nitric acid of the same concentration is used and does not volatilize, such that the recycling of a mother liquor can be realized. The method involves simple operations, has low production costs, greatly shortens the palladium extraction time, does not lead to secondary pollution, and meets the requirements of environmental protection.

摘要： A method for cleanly extracting metallic silver includes: mixing an acidic solution containing Ce4+ and NO3− with a silver-containing material for leaching; after the leaching is completed, carrying out a solid-liquid separation to obtain a leaching solution containing Ce3+ and Ag+; and electrolyzing the leaching solution, wherein an oxidation reaction of Ce3+ occurs at an anode to realize a regeneration of Ce4+ and an electrolytic reduction occurs at a cathode to reduce Ag+ to obtain the metallic silver. Ce4+ is used as a leaching agent and an intermediate oxidant to implement a cyclic operation of solution leaching and electrolytic regeneration on the silver-containing material. Almost no NOx and waste liquid are caused by the extraction process, and the invention is clean and environmentally friendly.
