Synthesis of Silicon Dioxide Xerogels and Their Sorption-Desorption Properties with Respect to Nicotine and Glycols

Composites based on silicon dioxide xerogels, containing glycerin and nicotine, were prepared by means of tetraethoxysilane hydrolysis using the single-stage synthesis and two-stage sorption procedures. In the single-stage synthesis, glycerin sorption 3 : 1 by weight with respect to the sorbent was achieved. The kinetics of the release (desorption) of nicotine from an aerosol mixture with glycols has been studied. The synthesized sorbent is promising for use in aerosol generating systems, and also as carriers and means of delivery of biologically active compounds and medicines.
