Abstract

The behaviour of tetramethyleneglycol towards aldehydes and ketones has been compared with that of ethyleneglycol and trimethyleneglycol. There is a certain disinclination to form the seven‐membered 1,3‐dioxepane ring. In several instances, open‐chain acetals have been obtained; many ketones did not react at all or only under relatively stringent conditions.

The infrared spectra of the condensation products have been determined and compared with those of the 1,3‐dioxolanes and 1,3‐dioxanes.

## Abstract With the aid of the molecular refraction and the infrared absorption, the structure of the condensation products of 3‐aminopropanol with 14 carbonyl compounds has been investigated. In some cases, tetrahydro‐1,3‐oxazines, in some Schiff bases, and in some, mixtures of these two possible
