摘要
本文在水相中合成了11种稀土硝酸盐与蛋氨酸的配合物,其通式为RE(Met)_4(NO_3)_3·4H_2O(RE=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Er,Y:Met=D—L—Methionine),利用DSC技术测得了它们的熔化焓和熔点。
The eleven complexes of rare earth nitrates with methionine were prepare in aqueous media,and the general formula of complexes is RE (Met)_4(NO_3)_3.4H_2O (RE=La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Er,Yi,Met = DL-α-Methionine). The moltenen thaipics and M.P of complexes have becn detemined with DSC.
