A process for the manufacture of an acetylenically unsaturated alcohol comprising reacting formaldehyde, an aldehyde or a ketone (a carbonyl compound) with acetylene in the presence of ammonia and a strongly basic macroporous anion exchange resin, the latter preferably featuring a polystyrene matrix and quaternary ammonium groups, preferably of type I or Type II. The reaction products, which depending on the starting carbonyl compound are propargyl alcohol or 1-monosubstituted or 1,1-disubstituted derivatives thereof, are of use as intermediates in the synthesis of many useful end products, inter alia in the field of vitamins and carotenoids.
一种制造乙炔基不饱和醇的工艺,包括甲醛、醛或酮(羰基化合物)与乙炔在氨和强碱性大孔阴离子交换树脂(后者最好具有聚苯乙烯基质和季铵基团,最好是 I 型或 II 型)存在下反应。根据起始羰基化合物的不同,反应产物为丙炔醇或其 1-单取代或 1,1-二取代衍生物,可用作合成许多有用最终产品的中间体,特别是在维生素和类胡萝卜素领域。
