Description

Technical Field

[0001] This utility model relates to the technical field of n-butyllithium dispensing, and in particular to a n-butyllithium dispensing bottle. Background Technology

[0002] n-Butyllithium is a common hazardous reagent in organic synthesis experiments. It is flammable upon contact with air, soluble in hydrocarbon and ether solvents, and reacts violently with water and other protic solvents when used in ether solvents. Improper handling during experiments can easily lead to combustion or explosion. Currently, commonly used laboratory n-butyllithium is packaged in glass bottles sealed with rubber stoppers. It requires a syringe or double-needle syringe for dispensing, and nitrogen gas is needed to balance the pressure. This method of dispensing presents hidden risks. When the syringe is removed, the pressure balance is unstable, and the reagent can easily spill onto the bottle opening or table, posing a danger upon contact with air. When using a double-needle syringe, the connection may be loose; the syringe and the connected PTFE tubing can easily detach, potentially causing the reagent bottle to tip over or spill. Utility Model Content

[0003] To address the problems of inconvenience and easy spillage when using n-butyllithium in the prior art, this utility model provides a n-butyllithium dispensing bottle;

[0004] The present invention provides a n-butyllithium dispensing bottle using the following technical solution:

[0005] A n-butyllithium dispensing bottle includes a bottle body and a cap. The bottle body has a double-layer structure of glass and stainless steel, making it more resistant to drops and impacts, and preventing reagent spillage. The cap has an inlet pipe and an outlet pipe. The inlet pipe has an inlet valve, and the outlet pipe has an outlet valve and a clip. The outlet pipe and the dispensing pipe are connected by the clip. The dispensing pipe has an air bladder and a dispensing needle, allowing the reagent inside to be emptied by squeezing the air bladder.

[0006] Preferably, the bottle body is composed of a two-layer structure consisting of a glass layer and a stainless steel layer.

[0007] Preferably, the stainless steel layer has a long, narrow, visible scale hole. The visible scale hole allows for easy observation of the amount of reagent remaining in the reagent bottle. The bottom of the stainless steel layer has a rubber pad to prevent slipping, making the bottle less likely to tip over and preventing reagent leakage.

[0008] Preferably, the inlet valve controls the flow rate of nitrogen gas. The outlet valve controls the dispensing rate of the reagent.

[0009] Preferably, a filter is provided in the middle of the buckle. The filter is designed to filter solids in the reagent bottle, preventing them from affecting the experimental system.

[0010] Preferably, the air inlet pipe, liquid outlet pipe, feed pipe, and air bag are all made of polytetrafluoroethylene.

[0011] Preferably, the air intake pipe is connected to an external nitrogen source.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] The n-butyllithium bottle features a double-layered structure made of glass and stainless steel, making it more resistant to drops and impacts, and preventing reagent spillage. A rubber pad at the bottom of the bottle provides anti-slip properties and prevents tipping. The inclusion of an inlet valve and dispensing valve allows for precise control of the reagent volume. The integrated cap and dispensing device, along with the air bladder, further minimize reagent spillage and reduce the risk of accidents. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings:

[0017] This utility model discloses a n-butyllithium dispensing bottle, such as... Figure 1 As shown, the device includes a bottle body 1 and a bottle cap 2. The bottle body 1 has an inner and outer layer of glass and stainless steel structure. A rubber pad 10 is provided at the bottom of the bottle body 1. The double-layer structure of glass and stainless steel makes the bottle body 1 more resistant to drops and impacts, and the reagent inside the bottle is less likely to spill. The rubber pad 10 provides anti-slip properties and prevents the bottle body 1 from tipping over. The stainless steel layer has a long strip-shaped visible scale hole 9, which is designed to facilitate observation of the amount of reagent remaining in the reagent bottle. The bottle cap 2 has an inlet pipe 3 and a liquid outlet pipe 4. The inlet pipe has an inlet valve 3a, which can adjust the flow rate of nitrogen gas. The liquid outlet pipe 4 has a liquid outlet valve 4a, which can adjust the flow rate of reagent. The liquid outlet pipe 4 and the feed pipe 6 are connected by a buckle 5. The buckle 5 has a filter 51, which can filter out solid insoluble substances in the reagent to avoid affecting the reaction system. The feeding tube 6 is equipped with an air bladder 7 and a feeding needle 8. The reagent inside the tube is emptied by squeezing the air bladder 7, and the reagent is added to the reaction system through the feeding needle 6.

[0018] The implementation principle of this utility model embodiment is as follows:

[0019] When n-butyllithium is needed, remove the n-butyllithium bottle, connect the inlet pipe 3 to an external nitrogen source, insert the feeding needle 8 on the feeding pipe 6 into the experimental apparatus, first open the outlet valve 4a, then open the inlet valve 3a, and turn on the nitrogen source. Nitrogen enters the reagent bottle, and n-butyllithium flows along the outlet pipe 4 through the buckle 5, filter 51, and air bag 7 into the feeding pipe 6, and then into the system through the feeding needle 8. The remaining amount of n-butyllithium can be seen through the visible scale hole 9. After the n-butyllithium is added, first turn off the nitrogen source, then close the inlet valve 3a, and then remove the nitrogen source. Close the outlet valve 4a, squeeze the air bag 7 to expel the n-butyllithium from the feeding pipe 6, and then pull out the feeding needle 8 to complete the feeding process.
