PROCESS FOR EQUILIBRATING ALLENE AND METHYLACETYLENE AND FOR RECOVERY OF PURE ALLENE FROM THE EQUILIBRIUM MIXTURE

摘要

Methylacetylene and allene are equilibrated by contact with potassium hydroxide in an inert solvent such as t-butanol. When mixtures of methylacetylene and allene are used in a chemical reaction such as the preparation of isopropenyl stearate from stearic acid and zinc stearate is the sole catalyst, methylacetylene is selectively absorbed by the stearic acid leaving behind highly purified allene. Alternatively, when potassium stearate is present with the zinc stearate and sufficient stearic acid is present, the allene-methylacetylene mixture is completely absorbed. The zinc stearate-potassium stearate co-function synergistically.
