Computed Properties of Al2H8O13S3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about Study on the structure and composition of anodic oxide films of aluminum. Author is Xu, Tao; Zhao, Jiazheng; Cheng, Jianming; Dang, Hongxin.
The structure and composition of the porous anodic oxide films of Al (abbreviated AOFAl) formed in oxalic acid (I) and H2SO4 (II) solutions, resp., were studied by TEM, IR and TGA. The porous anodic oxide films consist of a large number of hexagonal cells with an irregularly round pore in the center of each cell which penetrates vertically from surface to bottom, while a barrier layer under the film directly contacts with an Al substrate in a scallop shape. The content of Al2(C2O4)3 and Al2(SO4)3 in AOFAl (I) and (II) are ∼4.9% and ∼14.2%, resp.; ∼3.5% H2O of crystallization of Al2(SO4)3.xH2O which can be evolved at rather low temperature (∼85°) enriches between the cells and under the barrier layer of AOFAl (II); after irradiation by the electron beam of TEM the H2O of crystallization is removed and voids are formed.
