Photolytic. The vacuum UV photolysis (X = 147 nm) and y radio lysis of ethylenimine resulted in the formation of acetylene, methane, ethane, ethylene, hydrogen cyanide, methyl radicals, and hydrogen (Scala and Salomon, 1976). Photolysis of ethylenimine vapor at krypton and xenon lines yielded ethylene, ethane, methane, acetylene, propane, butane, hydrogen, ammonia, and ethylene-imino radicals (Iwasaki et al, 1973).

Table 3.3 gives the total uses of hydrogen. Ammonia production is by far the most important application, followed by methanol manufacture. Hydrogenations in petroleum refineries are an important use. Many other industries utilize hydrogen. Miscellaneous uses include hydrogenation of fats and oils in the food industry, reduction of the oxides of metals to the free metals, pure hydrogen chloride manufacture, and liquid hydrogen as rocket fuel. 

This device has shown stable gas sensitivity to hydrogen, ammonia, hydrocarbons, and CO up to temperatures of 500°C. Detection of hydrocarbons up to a temperature of 775°C has been demonstrated [65], but a slow drift was detected in the response at temperatures above 600°C. 

In the reductive amination of acetone carried out in the temperature range of 169-210°C the focus was laid on the selectivity changes at high conversion level. Experimental conditions, characteristic features of catalysts and corresponding activity and selectivity data obtained in the reductive amination of acetone are given in Table 2. It is noteworthy that in order to decrease the formation of isopropylalcohol by-product a relatively low hydrogen/ /ammonia molar ratio (H2/NH3 = D.5) has to be chosen. As seen in... 

A mixture of reactants and products in the equilibrium state is called an equilibrium mixture. In this chapter, we ll address a number of important questions about the composition of equilibrium mixtures What is the relationship between the concentrations of reactants and products in an equilibrium mixture How can we determine equilibrium concentrations from initial concentrations What factors can be exploited to alter the composition of an equilibrium mixture This last question is particularly important when choosing conditions for the synthesis of industrial chemicals such as hydrogen, ammonia, and lime (CaO).
