Abstract
The temperature dependence (300-400 K) of the quantitative adsorption of zinc (from reaction with diethyizinc) on Aerosilogel has been studi ed by the oilless high vacuum technique. Infrared spectra (3900-2700 c m-1) were obtained in situ for samples of Aerosilogel after treatment with diethylzinc. The temperature range (370-420 K) was established in which the zinc concentration was practically temperature independent. It is proposed from a comparison of results from analytical chemical and IR spectroscopic studies that the reaction of diethylzinc with sil anol groups determines the zinc content in the 370-420 K range.
