Polymerization of ethylene by oxide-supported titanium halide catalyst: kinetic model with a deactivation of active species
2000
Abstract The effect of the calcination temperature of alumina, which was then used as a support for a titanium halide catalyst [TiCl4/Et2AlCl], on the catalyst activity in ethylene polymerization was investigated. α-Al2O3 was found to make a more advantageous catalyst support as compared to γ-Al2O3 despite the fact that the former offered a clearly lower specific surface area and its content of surface OH groups was inferior. The ethylene polymerization in the presence of the catalytic system on different alumina supports was investigated on the basis of a proposed kinetic model, taking into consideration the deactivation of active sites in the process. The improved activity was found to re…

Effect of titanium (IV) application on some enzymatic activities in several developing stages of red pepper plants
1994
Abstract The effect of two titanium (IV) compounds, titanium ascorbate and titanium chloride, on some enzymatic activities, such as catalase, peroxidase, lipoxygenase and nitrate reductase in seeds, embryos, and seedlings and adult plants of red pepper (Capsicum annuum L.), was studied. A stimulatory effect of titanium was observed for every iron‐depending enzyme studied at all developing stages as well as for nitrate reductase but only for whole plants. This occurs because Ti+3/Ti+4 catalizes the activity of iron and enhances iron‐dependent enzymes.
