炔烴

Acetylenes are an important and valuable class of compounds in organic synthesis. 乙炔是在有機的綜合過程中的一種化合物的重要和有價值的種類。

Butynediol produced from acetylen(?) and formaldehyde contains about 1% of an unknown byproduct which is separated by distillation, extraction, recrystallization and column chromatography. 甲醛炔化制1,4-丁炔二醇的反應副產物中未知物約1%25,采用蒸餾、萃取、重結晶、柱層析等方法分離出未知物,純度可達97%25左右。
