Procedure:

To obtain butyl-vinegar ether, carefully mix 22 ml of butyl alcohol and 10 ml of concentrated acetic acid in a spherical round-bottomed 250 ml flask (1), carefully cooling under the tap. Carefully mix 5 ml of concentrated sulfuric acid into the resulting mixture. Once the mixture has cooled, an inverted (opposite) air cooler (2) dies on it and is mounted on an electric hob and boiled for 1 hour. Care should be taken to ensure that the condensing vapor layer is approximately in the middle of the refrigerator during boiling.

When the synthesis process is complete, the flask is cooled under water and diluted with water until two layers - water and ether layer - are formed. Using a separating funnel, the product-ether is separated and washed with a 10% soda solution to neutralize the unreacted H2SO4. Again the ether layer is separated and it is dried from the residual water with granular calcium chloride. The ether is then filtered and driven around a temperature of 123-1250S. The resulting pure ether tube (4) is collected.

As a result of the experiment, the output of the product is determined. Experiments are performed on different amounts of initial components:

	CN3SOON	S4N9ON	N2SO4
ML	10 20 10	22 22 10	5 5 -

The output of the product is determined by the following equation:

Gnaz is the theoretical amount of ether formation (calculated by the stoichiometric equation).
The first productthe weight is derived from its size and density, the density being determined using a densimeter.
Ga- the amount of ether produced in practice.
