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.
As a result of the experiment, the output of the product is determined. Experiments are performed on different amounts of initial components:
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. Download 0.69 Mb.
