摘要：

The paper shows that modification of amorphous silica with aluminum chloride leads to an increase in number of active sites on the surface of amorphous silica. The physical chemical and quantum chemical studies showed the chemical interaction between sulfur and aluminum (attached to the surface of amorphous silicate), as well as oxygen and silicon (a part of amorphous filler) using the donor-acceptor mechanism. It was shown that it was more efficient from the thermodynamic point of view when sulfur was added using the donor-acceptor mechanism due to vacant d-orbitals in the amorphous silica-aluminum chloride system.
