SYNTHESIS, CHARACTERIZATION AND PROPERTIES OF MAGNESIUM DI(EPSILON-CAPROLACTAMATE)

The various synthetic routes to the magnesium di(epsilon-caprolactamat e), CL2Mg, were investigated, primarily to establish reproducibility o f the route and purity of the products. The reactions of epsilon-capro lactam, CL, with diethylmagnesium, Et2Mg, in diethyl ether have proved to be the most favourable preparative method. The products, primarily CL2Mg and CLnMg, the later representing CL2Mg solvated with (n-2) CL, were characterised by IR, Raman, mass and NMR spectroscopies, includi ng methods of thermal analysis (TGA and DSC), and colligative properti es of their benzene solutions were studied as well. A particular atten tion was paid to the reactions of the products with water. (C) 1998 El sevier Science S.A. All rights reserved.
