Chemical interaction between titanium and nitrogen during mechanical activation is studied. The results demonstrate that mechanical activation of titanium powder in a planetary mill leads to a thermal explosion and the formation of titanium nitride nanopowder.

Removal oxygenates from wastewater is an important problem of lots of chemical industry. At last decade pervaporation makes a good competitive ability to traditional water-oxygenates separation methods. The goal of this work is to find a new generation of membrane material that can provide increased selectivity oxygenate separation in an example of 1-pentanol and 1-hexanol from the water. In this work were studied following polymers: polyhexylmethylsiloxane, polyheptylmethylsiloxane, and polyoctylmethylsiloxane in comparison with the material, which is wildly used in hydrophobic pervaporation – polydimethylsiloxane. The sorption properties of these polymers were studied and direct correlation sorption and pervaporation properties were demonstrated. It was found that polyheptylmethylsiloxane has higher selectivity than other study polymers: 22 – hexanol/water, 7.3 – pentanol/water.
