- W2616893319 abstract "A comparison between the initial reaction rates of nano- and commercial NaH has been studied in four test reactions: (1) hydrogenolysis of chlorobenzene; (2) selective reduction of cinnamaldehyde to cinnamyl alcohol; (3)metallation of dimethyl sulfoxide; (4) catalytic hydrogenation of 1-octene. The experimental results indicate that when NaH is used as a chemical reagent in the first three reactions, the initial reaction rates of nano-NaH is 230, 120 and 110 times higher than those of the commercial ones respectively, and it is in agreement with the difference in specific surface areas between these two forms of NaH. When NaH is used as a catalyst component together with Cp2TiCl2 in the fourth reaction, catalyst with nano-NaH gives extremely high activity in the hydrogenation of 1 -octene, while the one with commercial NaH gives no activity at all even if a large amount of the commercial NaH is used to make the total surface area equivalent to that of nano-NaH. Thus, it is evident that although large specific surface area is important for nano-NaH to be used as a catalyst component, high surface energy with surface defects seems to be more important. The large specific surface and the activated surface of nano-NaH with high surface energy should be the main factors for their extremely high chemical reactivity, while whether the former or the latter one plays a leading role depends on the type of reactions it is involved." @default.
