乙炔的, 炔属的,与乙炔相象的
The principal synthetic methods, production and application about the tertiary acetylenic alcohols in domestic and abroad are introduced in this paper. 本文介绍了国内外叔炔醇的合成方法、生产及应用。
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. 研究了烯丙基溴化锌、苄基溴化锌、芳基氯化锌、烷基氯化锌等有机锌试剂与炔基砜的碳锌化反应。
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-丁炔二醇的反应副产物中未知物约1%25,采用蒸馏、萃取、重结晶、柱层析等方法分离出未知物,纯度可达97%25左右。
