Versuchsvorschrift

A mixture of 5 g of chloral-hydrate, 10 ml of amyl-alcohol, 0.1 g of 4-methyl-sulphonic acid and 50 ml of benzene is kept at reflux temperature and the formed water is separated by means of a Dean-Stark apparatus. After a reaction time of 9 hours the benzene is washed with a sodium hydrogen carbonate solution and water, dried on magnesium sulfate, then it is vacuum-distilled.
