Abstract: Fourteen new rare earth para-aminosalicylates were synthesized and characterized by elemenial analysis, IR, UV, Molar conductance, TG-DTA, and X-ray powder diffraction, Their chemical formulae were proved to be RE(PAS)3nH2Owhere REare earth elements except Sc, Pm, Gd, PAS. para-aminosalicylate, n=1~3. The infrared spectra showed that rare earth elements are chelated by carboxyl group and hydroxyl group. Antituberculin and toxicity research showed rare earth para-aminosalicylates are less toxicity and alittle more efficient than sodium para-aminosalicylate in the inhibition of tuberculin.

Key words: Rare earth coordiation compound, Para-amino-salicylates, Synthesis, Charaeter
