ACTIVATION OF Мо2В CATALYST IN OCT-1-ENE EPOXIDATION WITH TERT-BUTYL HYDROPEROXIDE

The activation of Mo2B catalyst in the epoxidation of oct-1-ene with tert-butyl
hydroperoxide was researched. Dependences of the initial rate of hydroperoxide consumption
on the initial concentration of octene-1, tert-butyl hydroperoxide and the amount of catalyst in
the reaction mixture in the presence of an unactivated form of the Mo2B catalyst were studied.
The activation process can be described by the Avraami-Erofeev topokinetic equation and
includes two successive steps, viz., the nucleation and formation of a new active phase. The

Дослідження кінетичних закономірностей димеризації 2,3-диметилбута-1,3-дієну

Kinetic regularities of 2,3-dimethyl-buta-1,3-diene dimerization as a second-order reaction taking place in two parallel directions have been researched. Experimental kinetic data were obtained by gas chromatography. The activation parameters obtained for 2,3 dimethyl-buta-1,3-diene dimerization indicate that the reaction takes place in the kinetic region. Досліджено кінетичні закономірності димеризації 2,3-диметилбута-1,3-дієну як реакції другого порядку, яка відбувається за двома паралельними напрямками. Експериментальні кінетичні дані були отримані методом газохроматографічного аналізу.
