Creation of a variable-volume isobaric isothermal reactor - Application tothe study of the stoichiometry of monomethylhydrazine oxidation in aqueoussolution under stringent monophasic conditions

(T)he main object of this work was the conception and the building of an ex perimental device aiming at the study of chemical reactions in liquid mediu m under stringent monophasic conditions. Thus an isobar isotherm reactor ha s been made. Its original feature consists of a compensating piston which a llows reagents injection and sample withdrawal without appearence of gaseou s phase. The method has been successfully tested in the case of the oxidati on of the monomethylhydrazine in aqueous medium. The stoichiometry of the r eaction has been established.
