Potentiometric study of Cu (I) S-HMPT complexes in acetonitrile

Written by sctunisie no comments

Mixed complex formation reactions between CuCl and hexamethyl - thiophosphoramide (S - PMPT) have been studied, in acetonitrile at 25°C, by potentiometric measurements using a Cu (Hg) as indicator electrode. Results from graphical and numerical calculations methods demonstrated the formation of complexes. The superior order of which is equal to 3. However, the second method gives a better guarantee of precision. The results obtained by this method are β1 = 1,27.101, β2 = 1,89.102 and β3 = 3,97.103.
