Abstract

The physico-chemical characteristics of manganese soaps (caproate, caprylate and caprate) in solid state were investigated by infrared (IR), x-ray diffraction, magnetic and TGA measurements. The IR results revealed that the fatty acids exist in dimeric state through hydrogen bonding and manganese soaps possess ionic character. The x-ray analysis showed that manganese soaps have single-layer structure with molecular axes slightly inclined to the basal plane. The magnetic results suggested the presence of five unpaired electrons with octahedral geometry and possesssp 3 d 2 hybridization. The thermal decomposition of these soaps is kinetically of zero order and the energy of activation for the decomposition process lies in the range 9.2–12.8 K Cal mol−1.
