Partial Abrasion

Low-traumatic technology of grain separation from an ear is developed. It consists in influence of an air jet on an ear.It leads to rolling of an ear on a surface of the threshing device concave and causes its partial abrasion which is followed by grains separation. Process of wheat ears low-traumatic threshing in the experimental device yields satisfactory results, provides reduces grain endosperm damage on 10-12% in comparison with traditional technology. Germ of grain damage decreases by 5%.Crushing of grain made no more than 0,5%. Use of the developed technology of the low-traumatic threshing will allow to reduce grain damage of cereal crops in case of the harvesting. It is important by cereal breeding.

Mixed Carbonate

<p>Sodium aluminate is presented as a highly active heterogeneous catalyst able to convert a range of alcohols into the corresponding mixed carbonate esters, in high yield and under green conditions. The reaction is carried out using dimethyl carbonate both as a reactant and solvent, at 90°C. Allylic, aliphatic and aromatic alcohols are converted in good yields. The solid catalyst is shown to be truly heterogeneous, resistant to leaching, and recyclable. </p>
