Laboratory Hot Melt Reaction Pot
The hot melt glue reaction kettle included a rotating column, a stirring blade, a torsion-type trigger device, a stirring blade driving mechanism, and other components. The stirring blades were fixed to the rotating column and were used to stir the reaction chamber. When the twisting force trigger device detected that the twisting force of the stirring blade exceeded the preset value, it would send a switching signal to the stirring blade driving mechanism, so that one end of the stirring blade would withdraw from the outside of the rotating column, and the other end would extend out from the inside of the column. In addition, the rotating column was provided with a rubber scraping mouth on the moving path of the stirring blade, which could scrape off the gel on the stirring blade, thereby improving the hot melt glue reaction regularity and the finished product quality. In addition, a number of stirring blades can be arranged in the vertical direction of the rotating column, and each stirring blade has a separate torsion-force trigger device and driving device. The torsion-force triggering device includes a base of the torsion-force triggering device, a push rod, a compression spring, a first microswitch, and the like. However, the special requirements for the laboratory hot melt glue reactor or the difference between it and other reactors were not mentioned, so it was impossible to answer accurately.

What is the reaction type of the laboratory preparation equation for alkyls?
Alkane can be prepared by the reaction of an alkyls and metallic Na (Wurtz reaction), which is a type of free radical reaction. The reaction equation used the synthesis of diethylethyldimethoxysane from trimethylethyltrimethoxysane, bromic ether, and metallic Na as raw materials: 2CH3CH2Br2 + 2Na → CH3CH2-CH2CH3 + 2NaBr2. This reaction was a free radical reaction. In addition, alkyls were generally obtained from natural gas and oil. If pure alkyls were needed, they could also be synthesized. The substitution reaction of alkyls was a free radical substitution reaction (for example, the substitution reaction between alkyls and halos, the reaction conditions were light or high temperature), but this was not the main reaction type of alkyls. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction conditions of copper and concentrated sulfuric acid in the laboratory
The reaction between copper and concentrated sulfuric acid required heating. Under heating conditions, copper gradually dissolved and bubbles were formed. The gas produced could turn purple litmus red or the fuchsia solution faded. After cooling, the solution diluted and turned blue. The reaction equation was: CuSO4 + SO2 → +2H2O. At the same time, there are side reactions such as 5Cu +4H2SO4 (concentrated)(heating)= 3CuSO4 + Cu2S +4H2O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
