実験手順
To a solution of 50 g whey lactose in 150 ml of water there is added 1 ml of concentrated hydrochloric acid and 1/2 g of bromine. The mixture is heated to about 35° C. on a water bath. After a reaction period of about 1 hour under stirring, the solution becomes completely clear. The D-galactose is separated by evaporation in vacuo and is precipitated in the form of white crystals.
