| 摘 要： | 采用分光光度法研究了电子受体2,3-二氯-5,6-二氰基-1,4-对苯醌(DDBQ)与电子供体利多卡因(LD)的荷移反应,发现DDBQ与LD在乙腈中生成稳定的离子缔合物,并通过Job's plot确定DDBQ和LD的摩尔比为1:1.LD与DDBQ在587nm处形成强特征吸收峰.据此建立了一种测定注射液中LD含量的荷移分...

| Abstract: | The charge-transfer reaction of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone(DDBQ)as an electron acceptor with lidocaine as an electron donor was investigated by spectrophotometry.In acetonitrile,DDBQ was found to react with lidocaine and produce a stable charge-transfer complex,meanwhile the job's plot has been applied to establish the mole ratio of lidocaine to DDBQ with was found to be 1:1.The addition of lidocaine base to the DDBQ solution cause an immediate change in the absorption spectrum,with new chara... |
