Description
Technical field
The utility model relates to a kind of reaction unit for the experiment of hydrogen peroxide decomposition kinetics, belongs to experimental instrument and equipment technical field.
Background technology
The experiment of hydrogen peroxide decomposition kinetics has the features such as equipment is simple, intuitive is good, is a conventional teaching experiment of integrating theory with practice.But existing reaction unit is all to test under the condition that approaches room temperature, and hydrogen peroxide is widely used the bleaching of woods material as a kind of bleaching agent of green non-pollution, the industrial circles such as association with pulp bleaching, in actual applications, serviceability temperature is generally between 60-90 DEG C, existing reaction unit is tested under this temperature conditions, there is following problem: the data that read from the eudiometer tube of reaction unit at ambient temperature (1) are the volume of the oxygen that generates under constant temperature and pressure, decompose and generate oxygen volume and between the resolving time, have relation curve, but while at high temperature reaction, the oxygen of collecting not is the moment to keep constant temperature, when reaction starts, owing to having emitted hot oxygen, volume reading increases fast, then along with emitting the minimizing of gas, the gas cooling of initially emitting is shunk simultaneously, make volume reading increase partially slow, the above-mentioned relation curve of therefore making is nonsensical, (2) in whole mensuration process, the volume of air of wireway and eudiometer tube expands owing to being heated, even if the sample in reaction bulb has reached constant temperature, the reading on eudiometer tube also can constantly increase, and is difficult to read accurately a V
0value.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of simple in structure, handling safety is provided, is used in the reaction unit that carries out the experiment of hydrogen peroxide decomposition kinetics under higher temperature.
For achieving the above object, the utility model adopts following scheme:
A kind of reaction unit for the experiment of hydrogen peroxide decomposition kinetics, comprise reaction bulb, described reaction bulb is positioned at constant temperature water bath, and reaction bulb top is provided with rubber plug, and rubber plug is provided with sample feeding pipe and wireway, the other end of wireway is connected with cooling bottle, and extend in cooling bottle, cooling bottle is connected with eudiometer tube by conduit, and eudiometer tube lower end is connected with water level bottle by conduit, conduit is provided with cock, and described constant temperature water bath and cooling bottle are all placed on magnetic stirring apparatus.
