Abstract

The invention provides a chemical experiment distillation apparatus. The apparatus comprises a flask mounted on a first support, a condensing tube mounted on a second support, a thermometer, a liquid catching bottle, and a gas pipe through which the flask is connected to the condensing tube, an infusion tube through which the condensing tube is connected to the liquid catching bottle, a heater mounted on the first support, located right below the flask and provided with a heating cavity with an opening towards to the flask, and electric heating wires arranged on the inner peripheral side of the heating cavity; the heating cavity is matched with a flasket body at the lower end of the flask, and covers at least 2/3 of the flasket body; the flask, the gas pipe, the condensing tube, the infusion tube and the liquid catching bottle are sequentially arranged along the gas flowing direction; the thermometer is installed in the gas pipe in a sealed mode, and the lower end of the thermometer is placed in the flask. During the distillation experiment process, the lower end portion of the flask, containing liquid, is covered by the heating cavity of the heater, therefore, heating is even and efficient, and the heating efficiency of the liquid is improved. The way of using the electric heating wires to heat is adopted, thus open flames and polluting gases are not produced.

Description

technical field [0001] The invention relates to the field of chemical experiments, in particular to a chemical experiment distillation device. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the difference in the boiling points of the components in the mixed liquid or liquid-solid system to evaporate and recondense the components with low boiling points to separate the entire components. Therefore, distillation is a two-way process of evaporation and condensation. Compared with separation processes such as extraction and crystallization, distillation has the advantages of not introducing other solvents and maintaining the cleanliness of separated components, so it has been widely used. [0003] In the process of teaching chemistry, teachers need to use the chemical experiment distillation device to show students the distillation process. At present, the chemical experiment distillation devices used in many schools are relatively...
