Abstracts

EN

Investigation was carried out on the optimal conditions of the synthesis of NaVO3 and Cl2 from NaCl and V2O5 in the presence of the atmospheric oxygen. The influence of the excess of NaCl relative to V2O5 was investigated. Also the effect of the quartz sand introduced into the reaction mixture on the yield of the NaVO3 synthesis was determined. The obtained product of synthesis was isolated from the post-reaction mixture.
