乙炔的, 炔屬的,與乙炔相象的

The principal synthetic methods, production and application about the tertiary acetylenic alcohols in domestic and abroad are introduced in this paper. 本文介紹了國內(nèi)外叔炔醇的合成方法、生產(chǎn)及應(yīng)用。

Firstly, we studied the carbozincation of acetylenic sulfones with organozinc reagents, which include allyl zinc bromide, benzyl zinc bromide, aryl zinc chloride, alkyl zinc chloride and diethyl zinc. 研究了烯丙基溴化鋅、芐基溴化鋅、芳基氯化鋅、烷基氯化鋅等有機(jī)鋅試劑與炔基砜的碳鋅化反應(yīng)。

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(yīng)副產(chǎn)物中未知物約1%25,采用蒸餾、萃取、重結(jié)晶、柱層析等方法分離出未知物,純度可達(dá)97%25左右。
