Abstract
The catalytic influence of various Cu(II) salts and Cu(II)-chelate complexes of certain phenols and naphthols on potassium monopersulphate decomposition and vinyl polymerization of acrylonitrile has been investigated in aqueous medium. From the knowledge of the comparative rate data, the CuSO4/α-naphthol chelate complex was chosen for a detailed study of the kinetic aspects of acrylonitrile polymerization. The polymerization was studied at various concentrations of the reacting components and over a temperature range of 35—50°C. The rate of polymerization was found to be Rp=K[Cu(II)]0.169[α-N]0.512[KHSO5]1.1[AN]1.1The overall activation energy was computed to be 3.118 kcal mol−1 (13.03 kJ mol−1) and other thermodynamic parameters were evaluated. From the kinetic results and spectrophotometry studies on the interaction of KHSO5 and α-naphthol with Cu(II), the mechanism of KHSO5 decomposition and initiation of acrylonitrile polymerization are suggested.
