Tổng hợp và nghiên cứu tính chất và khảo sát khả năng thăng hoa một số pivalat đất hiếm

Abstract

Some complexes between rare-earth elements and pivalic acid Ln(Piv)₃.HPiv (Ln: Sm, Gd, Ho, Yb; HPiv: pivalic acid) were synthesized and their sublimation ability  have been studied. The synthesized complexes were studied by IR, thermal analysis and mass-spectroscopy methods. The obtained results show that pivalates evaporate comparatively well. The thermal separation of the pivalates is supposed as follows: Ln(Piv)₃.HPiv Ln(Piv)₃ evaporate and separate
