The influence of the reaction conditions on the selectivity of the interaction of oct-1-ene with tert-butyl hydroperoxide in the presence of MoB was investigated. It is shown that the selectivity of 1,2-epoxyoctane formation can vary depending on the reaction conditions.With the participation of the activated form of the catalyst, the selectivity increases significantly, but does not reach 100%. The optimal reaction conditions under which the selectivity of 1,2-epoxyoctane formation exceeds 90% have been established.

The article analyzes the main ways of search promotion of commercial Internet resources and features of their implementation of the promotion process are provided. The analysis of the concept  "Internet resource conversion” is conducted, the algorithm of its level evaluation is developed and internal and external factors that contribute to the promotion in the commercial segment are provided. An evaluation of the features of online resources reputation and scheme is developed as well as recommendations for its use in the promotion are submitted.

A new experimental-computational method for designing the catalytic converters for gases purification contaminated with hydrocarbons based on researched mechanism of heterogeneous catalytic process which stages are described by mathematical models is developed.

The conversion of langbeinite into schenite has been investigated under isothermal conditions within 273–333 K in the presence of mirabilite, sylvine and water. The reaction rate has been determined at various temperatures and “apparent” activation energy has been examined within 293–303 K. The reaction order by langbeinite has been determined as well.
