  • Publication number: 20250123051
    Abstract: A storage box and a refrigerator are provided. The storage box includes an item container comprising a box body; a container lid comprising a lid body and a connecting rod fixedly connected to the lid body and hinged to the box body; and a first container lid connecting mechanism, comprising an elastic telescopic mechanism and/or a rotary push mechanism. The elastic telescopic mechanism includes a first telescopic rod hinged to the connecting rod and the box body and an elastic member tending to lengthen the first telescopic rod. The rotary push mechanism includes a rotating member rotatably connected to the box body and non-rotationally connected to the connecting rod, and a translating member disposed outside the box body in a translatable manner with respect to the box body. The translating member is configured to translate by rotational movement of the rotating member or to rotate the rotating member.

  • Patent number: 10793512
    Abstract: Disclosed is a preparation method for a racemic adrenaline as represented by formula II. The method comprises the following steps: compound 1 is directly racemized in an acidic solution to produce compound 2, the acid solution comprising neither sodium bisulfite nor salicylic acid; and specifically comprises (a), in the acid solution of which the pH is 0.5-1.5, compound 1 is placed under the protection of nitrogen gas and, with the reaction temperature being controlled at 75-95° C., stirred and reacted for 1-3 hours; (b) the reaction solution is controlled at a temperature of 5-20° C., into which an activated carbon is added, under the protection of nitrogen gas, stirred for 20-40 minutes, and filtered, then a filtrate is collected; the filtrate is controlled at a temperature of 5-20° C., the pH thereof is adjusted using ammonia to 8.5-9.5, and is filtered when the pH is stabilized, and a filter cake is washed and dried to produce a high purity racemic adrenaline white powder.
