developed for fats and oils double bond hydrogenation and the existence of reasonable proposals for reaction pathways for selective hydrogenation of carboxymethyl groups, no such studies are found in the literature. Scheme 1

Restricted access

reaction rate laws, derived from the most plausible reaction mechanisms suggested in the literature, were tested using the kinetic data generated under differential reactor conditions. The extent of agreement between the experimental and model predicted

catalysts with 1, 3, and 10% Ag doping as well as silver-free were characterized by H 2 -TPR to obtain information on interaction between VO X species and dispersed silver. The results are shown in Fig. 3 . According to the literature [ 23 ], V 2 O 5

regarding the disposal of the large excess of mixed acids and generating nitrogen oxide (NO x ) fumes apart from added expense. A variety of heterogeneous catalytic nitration methods in which sulfuric acid is not used are described in the literature

and dip coating from stable precursor sols. The sources for Ti 4+ and W 6+ ions are the respective metal chlorides, dissolved in ethanol. The choice of WCl 6 is based on literature data reporting that the photocatalytic activity of Ti(W)O x powder

method provides high selectivity and yields of m -PDA at low cost. Although limited information is available in the literature on the kinetics of the hydrogenation of m -dinitrobenzene, it is reasonable to assume that m -dinitrobenzene behaves
