Abstract
PRODUCED on the plan now familiar to organic chemists and biochemists, the latest addition to this series contains details of thirty preparations. Among the open-chain substances are γ-aminobutyric acid, made by a modification of Gabriel's method ; ε-aminocaproic acid, prepared from 2-ketohexa-methylenimine ; and 1,3-butadiene. It is stated that between 25 gm. and 30 gm. per hour of crude butadiene may be produced by passing the vapour of cyclohexene over a cracking element, in an ingenious apparatus which is here fully described with the aid of a diagram.
