一般說明

氯仿-D(氘氯仿,CDCl3,氘代氯仿)是一种用于NMR(核磁共振)分析的标准纯度溶剂。由于其较高的化学和同位素纯度,在高分辨率核磁共振研究中得到广泛应用。关于氯仿-D在各种有机溶剂中碳-氘伸缩带的红外光谱定量研究已有报道。已有研究针对氯仿-d和液体氯仿的混合物进行了拉曼差分光谱研究,以评估CHCl3 和CDCl3的ν1 和ν2波段频移。

應用

1H NMR(质子核磁共振)光谱研究中,氘代氯仿被用作溶剂。31PPNMR(磷-31核磁共振)光谱研究磷酸三苯基和磷酸三(2-氯乙基)过程中,其用作溶剂。在2-(4-溴苄基)-3-羟基丙酸和3-羟基-2-(4-甲氧基苄基)丙酸的1H NMR谱研究中,它也用作氘化溶剂。此外,在3,3′-二羟基-4,4′-二氨基)-二联苯(HAB)和2,2′-双-(3,4-二羧酸)六氟丙烷二酐(6FDA)的1H NMR谱研究中,它也用作氘化溶剂。
