Multifunctional experimental reactor

Abstract

The invention discloses a multifunctional experimental reactor which is characterized in that the opening part of an outer tube (1) is connected with the outer wall of the upper part of an inner tube (2); the bottom of the inner tube (2) extends to the part close to the bottom of the outer tube (1); the upper part of the outer tube is provided with opened branch tubes (3) and (4); the upper part of the inner tube (2) is provided with an opened branch tube (5); the openings of the branch tube (4) and the inner tube (2) are respectively plugged by a rubber plug (6) and a rubber plug (7). The multifunctional experimental reactor has the advantages that 1, the experimental reactor can be used for preparing gases (such as hydrogen, oxygen, carbon dioxide and ammonia gas) and performing an experiment of comparing the heat stability of sodium bicarbonate with the heat stability of sodium carbonate, and a single-hole rubber plug or a double-hole rubber plug do not need to be processed, so that the operation is convenient, and the time is saved; 2, when a silver mirror reaction experiment is carried out, less water is used, and the temperature needed by the silver mirror reaction can be easily reached, so that the time and the alcohol fuel are saved.

Description

technical field [0001] The invention relates to a multifunctional reactor for gas preparation and property experiment in chemical experiments. Background technique [0002] At present, in classroom demonstration experiments or student group experiments: 1. When preparing (hydrogen, oxygen, carbon dioxide, ammonia, etc.) gases, and comparing the thermal stability of sodium bicarbonate and sodium carbonate, it is often necessary to process single-hole rubber. The stopper or double-hole rubber stopper is time-consuming and labor-intensive, and the rubber stopper is easy to age, which is inconvenient for long-term use; 2. During the silver mirror reaction experiment, it is necessary to heat the silver ammonia solution in a water bath, which consumes a lot of alcohol and wastes alcohol fuel. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the present invention provides a multifunctional experimental reactor, which is used for producing ...
