[Na.sup.+] ions with the higher energy state are more difficult to be exchanged, and organic cations enter gallery in three steps to occupy the positions of three kinds of [Na.sup.+] ions; intercalated organic cations are not bonded with oxygen in silica tetrahedron while locate stably above the hexatomic ring in tetrahedron (above octahedron that aluminum replaced by magnesium); organic cations intercalated latter have higher stability; no interlayer bonding water in organic intercalated Mt, rendering a stronger hydrophobicity than original Mt.
And then cyclodehydrogenation causes the particular sites C coupling to the other C end in a C-based hexatomic ring.
At high temperature, hexatomic ring was cracked into free radical I and II (Scheme 1(a)), and then free radical I and II recurred disproportionation reaction and generated 10-[(2-ethylhexyl)oxy]-10-oxodecanoate and 2-ethylhexene (peak 4, Scheme 1(b)).
