This invention discloses an optimized extraction and purification process for total flavonoids from Hypericum perforatum and its application in photodamage protection. Belonging to the field of natural product extraction technology, the process includes the following steps: using Hypericum perforatum powder as raw material, ultrasonic-assisted extraction is performed, followed by centrifugation, collection of the supernatant, and repeated extraction of the residue twice. The supernatants are combined to obtain a total flavonoid extract from Hypericum perforatum. The extract is then purified by adsorption using a macroporous adsorption resin, and the eluent is collected, concentrated, and dried to obtain high-purity total flavonoids from Hypericum perforatum. This invention features a stable process, high extraction efficiency, and is environmentally friendly, making it suitable for industrial production. The prepared total flavonoids from Hypericum perforatum exhibit high purity and significant antioxidant and photoprotective effects, and can be widely used in antioxidant, skin protection, and sunscreen products.

This invention belongs to the field of reconstituted tobacco technology, and provides a reconstituted tobacco based on a functional compound of Phyllanthus emblica and its preparation method. The reconstituted tobacco includes a porous composite substrate and a coating liquid. The Phyllanthus emblica functional compound includes Phyllanthus emblica pomace pulp and Phyllanthus emblica extract. The porous composite substrate is prepared by mixing and molding Phyllanthus emblica pomace pulp and tobacco pulp, wherein the Phyllanthus emblica pomace in the pulp has a porous and loose structure. The coating liquid is prepared by mixing Phyllanthus emblica extract and tobacco concentrate. The reconstituted tobacco prepared by the method of this invention can enhance the fruity sweetness and aroma of the reconstituted tobacco, improve its aroma quality, reduce its irritation, reduce its woody smell, and effectively improve the comfort of the reconstituted tobacco.

This invention belongs to the field of lithium battery electrolyte technology, specifically relating to a method for directly synthesizing thionyl chloride from LiFSI byproducts. The method involves mixing sulfur, a passivating agent, a catalyst, and a dehydrating agent, pretreating the mixture at high temperature, and then introducing a byproduct gas containing sulfur dioxide and hydrogen chloride, along with oxygen. A one-step synthesis reaction occurs at high temperature. After the reaction, the solid is filtered off to obtain thionyl chloride. This invention directly utilizes the LiFSI byproduct mixed gas without further treatment, converting it into the core raw material SOCl2, which can then be recycled for LiFSI production, achieving high-value utilization of the byproducts. The reaction in this invention is a one-step synthesis in a single reactor, eliminating the need for a high-temperature oxidation reactor and Cl2 storage and transportation system. This significantly simplifies the process, makes operation convenient, and reduces costs considerably. The reaction temperature does not exceed 130°C, making it easy to control and resulting in low energy consumption.

This application relates to a treatment device for ferric phosphate wastewater evaporation mother liquor, with a height-to-inner-diameter ratio ≥2.5, comprising: a shell; the shell including a cylindrical section and a conical bottom; a cap at the top of the cylindrical section; a stirring mechanism on the cap; an overflow port on the upper side wall of the cylindrical section; an overflow ring corresponding to the overflow port inside the cylindrical section; one end of a feed pipe communicating with the cap; the conical bottom communicating with the cylindrical section; a discharge port on the side wall of the conical bottom; and a volume ≥0.5 m³. 3 A heat exchange mechanism is fitted onto the outer surface of the cylindrical section and the conical bottom; the heat exchange mechanism is located between the overflow port and the discharge port; the height difference between the overflow port and the discharge port is ≥800mm. This device improves crystallization efficiency and crystallization effect by optimizing the shell structure.
