Synergistic Effect of BaCl2 on Corrosion Inhibition of Copper by Mentha Spicata Oil in 1M Nitric Acid: Gravimetric and Raman Spectroscopy Studies

“…[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. [36][37][38][39][40][41] By using these catalysts, the rate of hydroperoxide consumption flow rate increases over time.…”

“…[36][37][38][39][40][41] By using these catalysts, the rate of hydroperoxide consumption flow rate increases over time. 32,33,38,39,42 While in the case of Mo 2 B 5 catalyst such an increase in the reaction rate is associated with partial dissolution of the catalyst and formation of an active homogeneous form of the catalyst in the reaction mixture, 42 in the case of Mo 2 B, MoB, and MoB 2 catalysts it results from the catalyst surface activation. 33,38,40 The process of the epoxidation of octene-1 and ethylallyl ethylacrylate in the presence of the activated forms of these catalysts has been studied in sufficient details.…”

The effect of reaction conditions on MoB activation in 1-octene epoxidation with tert-butyl hydroperoxide

“…The most efficients catalysts for this process are molybdenum containing compounds, including molybdenum borides [4][5][6][7][8]. It was shown earlier [9][10][11][12][13][14] that 1 octene and ethylallyl ethylacrylate are easily epoxidized with a selectivity of more than 90% in the presence of molybdenum borides. The cata lytic activity of these catalysts increases with time, and this change is described by the Avrami-Erofeev topok inetic equation.…”
