Propargyl Alcohol

CAS RN:107-19-7

Reactivities / Incompatibilities

Addition of phosphorus pentoxide to propargyl alcohol caused the alcohol to burst into flame.

Phosphorus pentoxide, oxidizers.

If propargyl alcohol and similar acetylene compounds are dried with alkali before distillation, the residue may explode (probably owing to salt formation). Sodium sulfate is recommended as a suitable desiccant.

... Hydroxyacetone was being prepared on half the scale by treating propargyl alcohol as a 30% aq soln with mercury sulfate and sulfuric acid (6 g and 0.6 g/mol of alcohol, respectively). On stirring and warming the mixture to 70 deg C a violent exothermic eruption occurred. Quartering the scale of operations to 1 g/mol and reducing the amount of acid to 0.37 g/mol gave a controllable reaction at 70 deg C. Adding the alcohol to the other reactants at 70 deg C is an alternative possibility to avoid the suspected protonation and polymerization of the propargyl alcohol.

... Reacts violently with oxidants. Attacks many plastics.
