ABSTRACT:
A process permitting hazard free purification by distillation of compounds which are distillable per se but which present the risk of explosive decomposition under the effect of elevated temperatures. A desensitizing substance is added to the compounds to be distilled.
Aliphatic alcohols for instance are suitable additives for alkinols.
Examples are provided for the distillation of butinediol-1,4 together with the additive glycerin.
