実験手順
A mixture of 42 g (0.2 mol) 3,4-dichlorobenzoyl chloride and 200 ml ethanol was heated to boiling for 2 hours, evaporated, the residue taken up in ether, the solution washed with NaHCO3 -solution and water, dried and evaporated. The distillation yielded 32 g (73% theor.) ethyl-3,4-dichlorobenzoate with a BP of 84° C./0.13 mbar and a mp of 33° to 35° C.
