Preparation of of acetaldehyde ammonia trimer
A condenser filled with warm 30° C water is attached to reaction flask containing crude acetaldehyde. Acetaldehyde should fill no more than two thirds of the flask. To the top of the condenser, a glass tube is attached which is connected to a wash bottle filled with 50 ml of ether. In additional, a second wash bottle containing 50 ml of ether is connected to the first. The crude acetaldehyde is then gently boiled and the distilled vapors are absorbed by ether. When the distillation process is complete the ethereal solutions are combined and transferred in a beaker cooled with a salt-ice bath. To the ethereal solution of acetaldehyde, a dry ammonia is bumbled through a funnel or wide tube immersed near the bottom of the solution. When the solution is saturated with ammonia and (this can take 1 hour) acetaldehyde ammonia trimer is separated out. Acetaldehyde ammonia trimer is collected by filtration, washed with a small amount of ether, and allow them to dry in a desiccator or vacuum. The yield of is acetaldehyde ammonia trimer about 30 g.
