A series of porous composite SiO2-TiO2 and pure TiO2 spherical particles were prepared via the peroxo route and subsequently used as the support for catalyst. Aminopropyltrimethoxysilane (APTMS) was grafted to the surface of support in the strictly unhydrous media leading to bonding of free amino groups to the support surface covalently. Procedure of APTMS grafting is easy to perform and may be spread for grafting other different functional groups to the inorganic surfaces of the catalyst support. The support samples were calcined at various temperatures in order to optimize the preparation conditions and boost the density of surface amino groups. It has been found that the quantity of grafted APTMS varies insignificantly for the different support samples. Grafted amino groups would be applied as active catalytic sites in different reactions of organic chemistry such as acylation of amines and alcohols, polymerization of lactones with hydroxyl groups, isomerization of unsaturated co...
A new peroxo-method for Mg-Zr mixed oxide preparation has been applied. It has been established that this precursor after being heated up to 700 ºC is in the form of poorly crystalline Mg-Zr oxide. Thermal and X-ray diffractional analyses have shown that the oxide phase is formed directly from amorphous peroxocomplex, avoiding formation of intermediate Mg(OH) 2 phase. The peroxocomplex-mediated route allows achieving high degree of molecular homogeneity in the mixed oxide and high distribution of the active sites due to its low crystallinity. The prepared material is a potential catalyst for aldol condensation reaction.

для логистики на данном уровне характерен комплекс услуг, в основе которого лежит механизм субподряда: набор услуг предоставляется в конечном итоге одним оператором, но комплексность достигается тем, что в процессе участвуют несколько компаний, «сторон», интегрируемых им по всей длине распределительной цепи.
