以二丙酮醇为有机物Ce~(3 )为催化剂的BR型化学振荡反应的研究

BR型化学振荡反应目前研究很少。该反应机理大多参照BZ反应中较为公认的FKN机理。有些文献已作了报导以.二丙酮醇(CH_3)_2C(OH)CH_2C(O)CH_3(Diacetone alcohol,以下简称DA)为有机物,Ce~(3 )为催化剂的BR型反应还未见报导。     

以二丙酮醇为有机物Ce3+为催化剂的BR型化学振荡反应的研究

The oscillatary behavior of diacetone alcohol(DA)-KIO_3-H_2O_2-H_2SO_4-Ce~(3+) system has been studied.The system may oscillate in the concentration ranges of H_2SO_4 0.11—0.24, KIO_3 0.019—0.048; Ce~(3+) 5.95×10~(-4)—3.57×10~(-3), DA 0.4—3.22 and H_2O_2 0.40—1.99 mol·dm~(-3) respectively. Using Hg_2SO_4 electrode as the reference electrode, the potential of I~- and the redox potential show oscillatary wave behavior in XWT balance recorder. According to our expreimental results, We may said seen that ...
