Abstract

Ketene was prepared from acetoneK by pyrolysis. Instead of distilling the acetone into the reaction tube it was dropped in directly from a separatory funnel. In this way, such a rapid flow of acetone was maintained that the extent of decomposition at 700” was limited to &6%. Thus, from 108 g. of acetone 102 g. was recovered in an experiment lasting thirty minutes. The other 6 g. gave rise to a 72y0 yield of ketene since 10 g. of acetanilide was produced ...
