【摘要】 用二醛1,7—=（2′—甲酰基苯基）—4—苄基—1,7—二氧杂—4—氮杂庚烷,以 NaAc 为中和剂,乙醇为溶剂和盐酸羟胺（NH₂OH·HCl）反应制得了开链聚醚1,7—=（2′—肟甲基苯基）—4—苄基—1,7—二氧杂—4—氮杂庚烷（L）。用元素分析、红外光谱、核磁共振氢谱及质谱等手段对它进行了表征,并较详细地讨论了基质谱的裂解机理.更多还原

【Abstract】 By the reaction of the dialdehyde respectively with NH₂OH·HCI and NaAc in ethanol,a new open-chain polyether is obtained with two oximido groups at the end of the chain. The dialdehyde is 1,7-bis（2’-formy lphenyl）-4—benzyl—1,7—dioxa—4—aza heptane（A）. The open-chain polyether is 1,7—bis（2’—oximido methylphenyl）—4—benyl—1,7—dioxa—4 —azaheptane（L）.The structure of L was characterized by IR,HNMR,MS and elemental analy- sis.The mass spectrum data for L has been discussed in detail.更多还原
