[General Description]

4-Chlorobutyrophenone is a chloro ketone. Preparation of 4-chlorobutyrophenone is reported.
[Purification Methods]

Fractionate the ketone several times using a short column. It recrystallises from pet ether at -20o as glistening white rosettes and is filtered at 0o, and dried in a vacuum desiccator over H2SO4. The semicarbazone has m 136-137o. [Conant et al. J Am Chem Soc 46 1882 1924, Cloke J Chem Soc 1174 1929, Hart & Curtis J Am Chem Soc 79 931 1957, Beilstein 7 IV 711.]
