Abstract

ALDEHYDES and ketones decompose in the gas phase in two main ways1. Type I, predominant with short chain compounds, may be represented RCOR' → CO + (RR + RR' + R'R'). Type II, predominant with long-chain compounds, involves a cracking of the long hydrocarbon chain in a position α–β to the carbonyl group, giving a lower carbonyl compound and an olefine.
