An experimental investigation of thermal cracking of n-nonane in a laboratory-scale flow reactor was carried out. The reactor was operated at atmospheric pressure. Experimental data were obtained for the temperature range of 650-750°C and the nonane flow rate varied from 0.13 mol/hr to 1.3 mol/hr. An analysis of the overall kinetics of decomposition indicated that the order of the decomposition reaction and the frequency factor and the activation energy for the decomposition rate constant are approximately 1.0, 2.01 X 1 014 sec-1 and 63 kcal/g-mol respectively. The measured product distributions agreed reasonably well with the ones predicted from Rice's theory. Woinsky's model has been found to correlate approximately with the results of the present study. The empirical method of severity function correlation applies well to the products of nonane decomposition.Cracking of hydrocarbons has been extensively studied since the beginning of this century. During the 1930's, interest developed significantly in these reactions. At this time,

different classes of alcohols generated in this work, it is now possible to predict reverse osmosis separations of many alcohol solutes from data on membrane specifications given in terms of A and Dam/K6 for NaCl only. This predictability is illustrated in this paper for the Ci to Cg alcohols using cellulose acetate membranes of different surface porosities. This prediction technique can be extended to a wide variety of organic solutes in aqueous solutions where reverse osmosis separations are governed by polar, steric, and/or nonpolar effects and preferential sorption of water at the membrane-solution interface. This possibility opens new areas of reverse osmosis investigations involving a wide variety of organic solutes many of which are of practical interest from the point of view of water pollution control.Literature Cited
