実験手順

A solution of 155.5 g (1 mole) of 3,5-dichloro-2-pentanone with 83 g (1.024 moles) of sodium rhodanide in 1 litre of methyl-ethyl-ketone is boiled for 1 hour under stirring. Then the procedure described in Example 1 is followed. 171 g (96.2%) of 3-thiocyanato-5-chloro-2-pentanone are obtained, which after distillation identical in all respect with the product of Example 1.
