Versuchsvorschrift

A mixture of 0.70 g of 1-benzylideneamino-2-methylimino-3-propyl-imidazolidine in the form of a hydroiodide in 20 ml of water H2O with 10 ml of an anion exchange resin in chloride form (Amberlite IRA-400 (Cl)R) is stirred for ca. 3 hours at room temperature, the anion exchange resin is filtrated off and the filtrate obtained is treated with 3.6 ml of 2 M HCl. Benzaldehyde is distilled off from the mixture obtained by steam distillation. From the remaining mixture the solvent is evaporated off. 1-Amino-2-methylimino-3-propyl-imidazolidine in the form of a hydrochloride is obtained in the form of an oil.
