“…Therefore, much attention has been focused on the application of different catalysts on the base of transition metal for the epoxidation process. [26][27][28][29][30][31] Among them, molybdenum compounds show much promise due to high catalytic activity. [32][33][34][35] In particular, molybdenum boride catalysts are quite effective in the epoxidation reactions of olefins with tert-butyl hydroperoxide.…”

The effect of Mentha Spicata oil and the mixture of BaCl2 and Mentha Spicata oil on corrosion of copper in 1M HNO3 have been investigated using weight loss methods and Raman spectroscopy. The study revealed that copper is more efficiently inhibited by Mentha Spicata oil in the presence of BaCl2 than pure oil. The inhibition efficiencies increased with increased concentration of the additives. The highest inhibition efficiency of 56.12 % was observed with single Mentha Spicata oil. An improved inhibition efficiency of 75.13 % was observed with the mixture of Mentha Spicata oil and BaCl2 at 298 K in 1M HNO3, an effect attributed to synergism between Mentha Spicata oil and BaCl2. Inhibition efficiency decreased with increase in temperature from 298-328 K. The adsorption of inhibitor molecules on metal surface followed Frumkin and Langmuir isotherm. Thermodynamic parameters such as enthalpy ∆H, free energy of adsorption ∆G and entropy of adsorption are obtained from experimental temperatures ranging from 298-328 K. Raman Spectroscopy and mapping were used to characterize the surface layers.

The regularities of Mo2B catalyst activation in the epoxidation reaction of alfa-ethylallyl ethyl acrylate with tert-butyl hydroperoxide have been studied. It has been shown that the catalyst activation process is described by the Avrami-Erofeev topokinetic equation and includes two successive stages – the nucleation and formation of a new phase active in the epoxidation reaction. The formation of epoxy only occurs in the presence of the activated form of the catalyst. The effective and topochemical process constants have been calculated.

During organochlorine wastes thermal utilization formed at direct chlorination of ethylene to 1,2-dichloroethane in the production of vinyl chloride at Karpatnaftohim LLC, the ash is formed, which clogs gas pipelines and heat exchange elements of the steam generator, causes disruption of normal technological process and leads to emergency shutdowns.The composition of this ash was determined by chemical methods of quantitative analysis and flame photometry for such macrocomponents as Fe2O3 (28%) and FeCl3 (5%), as well as magnesium chlorides (30%) and sodium (4%), the rest (about 32% ) probably resinous highly chlorinated unburned components of VAT residues, carbon particles and nitric acid-insoluble iron compounds. Utilization methods and possible ways to reduce the amount of ash from the organochlorine waste combustion formed at the production of vinyl chloride are briefly considered.
