Description

A laboratory water separator

Technical field

The utility model belongs to the technical field of laboratory appliances, and specifically relates to a water distributor for a laboratory.

Background technique

The water separator is mainly used to separate the water generated by chemical reactions in chemical experiments. Since the presence of water in the chemical reaction during the experiment will have a certain impact on the reaction or prevent the reaction from proceeding forward, the water separator is usually connected to the flask. , the water generated in the flask needs to be brought out through a solvent that azeotropes with water, so that the reaction can proceed. After condensation, the solvent and water are separated into layers in the water separator, the water in the lower layer is discharged, and the solvent in the upper layer refluxes to continue the reaction. To produce water, toluene and water are usually used to azeotrope to take away the water generated by the reaction. At present, there are often some problems when using water separators. The gas in some water separators condenses prematurely, so that the water returns directly to the flask, and the water separation effect is poor.
