Description

Technical Field

[0001] The utility model relates to the technical field of distillation experiments, in particular to an oil distillation experimental device. Background Art

[0002] Distillation is a thermodynamic separation process. It uses the different boiling points of the components in a mixed liquid or liquid-solid system to evaporate the low-boiling component and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, it has the advantage of not requiring the use of other solvents other than the system components, thus ensuring that no new impurities are introduced. The combined operation of first heating the liquid to boiling, then turning the liquid into steam, and finally cooling the steam and condensing it into a liquid is called distillation. In chemical experiments, the commonly used distillation apparatus is generally composed of a distillation flask, a thermometer, a condenser, a liquid receiving tube and a receiving bottle.

[0003] The existing distillation device does not have an ideal fixing effect on the distillation flask, and the distillation flask is prone to tilting or falling.

[0004] A chemical experiment distillation device is proposed in the patent document with the publication number CN213823483U, which includes a bottom plate, a heating block, a distillation flask and a receiving cup.
