実験手順
Iodine is added portionwise to a mixture of 4 g of 3-dimethylaminopropylmercaptan in 60 ml of ether and 30 ml of 2-N sodium hydroxide solution until the solution is no longer decolorised each time (ca 4.2 g of iodine). After stirring for 1 hour, the ether phase is dried over magnesium sulphate, concentrated and fractionally distilled at 95°-100° C./0.025 mmHg. 2.7 g (68%) of 3-dimethylaminopropyl disulphide are obtained in the form of a clear colourless liquid.
