Reaction vessels are: ① test tubes, evaporation dishes, crucibles, burning spoons, etc.; ② can be heated but must be padded with asbestos mesh instruments beakers, flasks, conical flasks, etc.; ③ can not be heated instruments: gas cylinder, funnel, etc..
Reaction vessel is used to carry out chemical reactions of substances in a class of container equipment, common reactor, generator, reactor, decomposition tower, synthesis tower, polymerization kettle and other reactions. Most of the reaction within the container is at high temperature, high pressure, or even ultra-high pressure conditions, the raw materials involved in the reaction as well as catalysts are mostly flammable, explosive substances, the reaction process will cause fire and explosion if you are not careful, the incidence of accidents is high. Reaction vessel explosion generated by the powerful shock wave and toxic, flammable, explosive material leakage caused by the fire easily lead to the collapse of the building, a large number of casualties, and some even cause chain explosions, the entire workshop, plant leveled. Strengthen the research on the reaction vessel fire and explosion accidents, it is very important to prevent the occurrence of such accidents.
