The reduction of a nitrate, for example potassium nitrate, by iron(ll) sulphate in the presence of concentrated sulphuric acid gives reasonably pure nitrogen monoxide. The mixture is warmed and at this temperature the nitrogen monoxide produced does not combine with uncharged iron(II) sulphate (see below). 

If this reaction takes place in air, the evolved nitrogen monoxide is oxidised to the dioxide and this dissolves again as in equation (9.1) hence virtually complete conversion of nitrogen dioxide to nitric acid can occur (see nitric acid, below). With alkalis, a mixture of nitrite and nitrate is formed ... 

Nonporous silver membrane tube (99.99 wt.% Ag), (in double pipe configurationX thickness 100/im. Feed enters the reactor at shell side, oxygen at tube side. Oxidation of ammonia. Silver catalyst in membrane form (see previous column). Oxidation of ethanol to acetaldehyde. Silver catalyst in membrane form (see previous column). r- 250-380°C. The yield of nitrogen was 40%, the yield of nitrogen monoxide was 25%. r- 250-380°C. The yield of acetaldehyde was 83%. The yield with bulk powdered silver catalyst was 56%.

The signal transduction pathways that mediate the effects of the metabolic hormone insulin are of particular medical interest (see A). The mediator nitrogen monoxide (NO) is also clinically important, as it regulates vascular caliber and thus the body s perfusion with blood (see B). 

Nitrogen monoxide (NO) is a short-lived radical that functions as a locally acting mediator (see p. 370). 

The results obtained corresponding to the consumption of paraxylene and the formation of PTN (see Figs. 3 and 4) are interpreted by a redox mechanism which implies a stationary state whith equality between the rates of the two steps of reduction of the catalyst by paraxylene and its oxidation by nitrogen monoxide (ref. 3). Table 3 gives the values of the rate constants of the two steps and shows that Kq and calculated for the consumption of paraxylene or the formation of paratolunitrile, the main product, are very similar in agreement with the redox mechanism. 

Mass Balance around the Absorption Column The mass balance around this unit was refined due to the availability of better chemical equilibrium data (Ref. Al, see Chapter 9). This data predicted that the dissolved gas concentration in the red product acid stream flowing from the column would in fact be of lower concentration than initially thought, and the dissolved gas component tended to be nitrogen monoxide and dioxide rather than nitrogen tetroxide. Therefore,...
