Abstract

The deintercalation process for the first stage fluorinated graphite inclusion compound C2F0.92Br0.01·0.285CH3CN was studied under isothermal conditions. It was shown by a combination of gravimetric and X ray diffraction methods that the decomposition of the first stage inclusion compound into the second stage compound (and gaseous CH3CN) under isothermal conditions proceeds through the mixed-layer state that simultaneously consists of three main microphases: the first, the second and the fourth stages of filling with their identity periods 9.42, 15.50 and 27.8 Å, respectively, and of the second stage of filling in its labile extended state with the identity period of about 16.3 Å. It follows from structural properties that the C–C bonds of “guest” molecules are mostly coplanar with the fluorocarbon layers of the “host” matrix.
