Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Pyridylethylaminopropylpolysiloxane xerogel (PEAPPSX) was synthesized by sol-gel technology. The composition of the substance was determined via elemental analysis and 1H NMR spectroscopy. The surface structural characteristics of the xerogel were determined by electron microscopy and low-temperature nitrogen sorption; thermal analysis was also performed. It was established that the content of functional groups in PEAPPSX was 2.43 mmol/g, and that xerogel is a mesoporous substance with a developed surface (121.71 m(2)/g) \\\\Expert2\\nbo\\Russian Journal of Physical Chemistry A, Focus on Chemistry\\2011, V.85, N 3, p.478.pdf |
