All of these compounds react rapidly with chlorine and we now record some observations on the products to which they lead. Chloro-4-butadiene-1, 2 in a series of experiments was chlorinated under various conditions and the combined distillable product was redistilled through an efficient column. Most of the material segregated into two fractions, one boiling at 40 to 41'at 10 mm. and the other at 64 to 65'at 10 mm. The lower boiling compound on ...
