Research output: Contribution to journalArticle


An industrial method of synthesizing p-diethynylbenzene is proposed which is based on the bromination of commercial p-divinylbenzene and the subsequent dehydrobromination of the 1,4-bis (dibromethyl) benzene formed. The proposed method differs from the existing one in that dehydrohalogenation is not carried out with an alkali solution but with a suspension of caustic potash in a hydrocarbon solvent. The reaction catalysts are aliphatic alcohols in amounts not exceeding 1% of the alkali mass.
