The optimun reactions conditions are: molar ratio of ethylene oxide to phosphorous oxychloride=3.10∶1.00, catalyst amount 1.5%, 5 h and 30~45 ℃.展开更多
Solid complex of terbium nitrate with a novel tetrapodal ligand, 1,1,1′,1′-tetra(2-pyridinecarboxylester)-di(trimethylpropane) was prepared.

This new complex with the formula of [TbL(NO3)](NO3)2·2H2O was charact-erized by elemental analysis, molar conductivity, IR spectroscopy and thermal analysis. At the same time, the luminescent property of the complex was also studied.展开更多
