摘要
本文利用红外光谱法对胆红素－氟化钡体系的固相研磨反应进行了研究。结果表明该固相研磨反应具有氧参加的自由基反应机制，并且反应产物中胆红素与钡离子的络合形式与液相反应合成的胆红素钡络合物不同。
Bilirubinate complexes are the main component of pigment gallstones and the recent researches suggested that bilirubin free radical plays a role in some biological processes.In this paper the solid state reaction of bilirubin on BaF 2 was examined by FT IR.The solid state reaction was produced by grinding the crystalline bilirubin and single crystals BaF 2 together in an agate mortar.From the results the free radical mechanism is suggested in the solid state reaction of bilirubin on BaF 2.The replacement of H on NH of pyrrole by Ba 2+ was prior to that of H on COOH.The sturcture of the resultant complex from the solid state reaction is different compared with that from the liquid state reaction.
