Description

N-butyl lithium taking bottle Technical Field The utility model relates to the technical field of n-butyllithium taking, in particular to a n-butyllithium taking bottle. Background N-butyllithium is a common hazardous reagent in organic synthesis experiments. When the catalyst is contacted with air, the catalyst can catch fire, is dissolved in hydrocarbon and ether solvents, is used in the ether solvents, and can react violently when meeting water and other proton solvents. Such hazardous reagents are prone to combustion or explosion accidents during the course of the experiment if they are not properly operated. Currently, the common n-butyllithium in laboratories is packaged in glass bottles, and rubber stoppers are sealed. A syringe or double needle access is required, while nitrogen is also required to balance the air pressure. The taking mode has hidden risks, when the syringe is taken out, the air pressure balance is unstable, the reagent is easy to spill on the bottle mouth or the table top, and dangerous accidents are easy to occur when the reagent contacts with air. When using the duplex needle to get, adapting unit is not firm, and the duplex needle all easily drops with the polytetrafluoroethylene pipe of connection, can cause the toppling over of reagent bottle or unrestrained emergence accident. Disclosure of utility model In order to solve the problems that the taking of the n-butyl lithium is inconvenient and the n-butyl lithium is easy to spill during taking in the prior art, the utility model provides a n-butyl lithium taking bottle; The utility model provides an n-butyl lithium taking bottle which adopts the following technical scheme: The utility model provides a bottle is used to n-butyl lithium, includes body and bottle lid, its characterized in that, the body is equipped with inside and outside two-layer structure, and glass and stainless steel's bilayer structure makes the body more resistant fall, resistant collide with, and the reagent is difficult for spilling in the bottle leaks. Be equipped with intake pipe and drain pipe on the bottle lid, be equipped with the admission valve in the intake pipe, be equipped with drain valve and buckle on the drain pipe, connect drain pipe and charging tube through the buckle, be equipped with gasbag and charging needle on the charging tube, can make the reagent evacuation in the pipe through the extrusion gasbag. Preferably, the bottle body is formed by combining a glass layer and a stainless steel layer. Preferably, the stainless steel layer is provided with a strip-shaped visual scale hole, the setting of the visual scale hole can facilitate the observation of the residual amount of the reagent in the reagent bottle, and the bottom of the stainless steel layer is provided with a rubber pad, so that the reagent bottle has the function of skid resistance, and the bottle body is not easy to fall down, and the reagent in the bottle is not easy to scatter and leak. Preferably, the inlet valve controls the flow rate of nitrogen. The liquid outlet valve can control the liquid outlet speed of the reagent. Preferably, a filter disc is arranged in the middle of the buckle. The setting of the filter disc can filter the solid matters in the reagent bottle, so that the influence on an experiment system is avoided. Preferably, the air inlet pipe, the liquid outlet pipe, the feeding pipe and the air bag are made of tetrafluoro polyethylene.
