Leader of the group:  

Galashina Valentina N.
Senior Scientist,  Institute of Solution Chemistry ;
Ph.D 1989, Ivanovo Institute of Chemical Technology

The main efforts are concentrated on the following problems:

bullet5.gif (101 bytes)   Theoretical foundation and creation of technological methods to promote structural transformations of cotton cellulose in sodium hydroxide solutions of high concentrations (4.0-4.5 M);
bullet5.gif (101 bytes)    Kinetics and mechanisms of hydrolytic and oxidation destruction of cellulose natural satellites;
bullet5.gif (101 bytes)    Correlations between the nature of complexing agents ( the derivatives of carboxylic and phosphonic acids) and their ability to influence the bleaching of cotton fabric in alkaline media at 70-1000C.
