A study of Acetyleneglycols (VIII) : Synthesis of 2,5-dimethyl-3-hexyne-2,5-diol from carbide and acetone, introducing acetylene gas together

摘要

In a preparation of 2,5-dimethyl-3-hexyne-2,5-diol from calcium carbide powder and acetone in ethyl ether in presence of KOH, we have found that yield of the diol has teen increased when acetylene gas has been used together. The yield was 63.4%.
