The vapor phase Beckmann rearrangement of cyclohexanone oxime(CHO)over RBS-1 catalyst was carried out in a continuous flow fixed bed reactor under atmosphere pressure. 在常压连续流动固定床反应装置上,考察了反应温度、环己酮肟质量空速(MHSV)、溶剂种类、环己酮肟浓度、载气流量、水的质量分数等反应条件或...
An acyloin-type rearrangement is an acid-catalyzed reorganization of α-hydroxy ketones (13.31), also known as acyloins (Scheme 13.14). These acid-catalyzed [1,2]-alkyl migration reactions also can involve other types of molecules, such as glycols (pinacol rearrangement), α-diketones (benzil–...
