To determine the amount of methanol required to reduce the nitrate, one has to proceed iteratively, i.e. a certain amount of methanol is added step by step using the keyword REACTION (e g. 0.1 1 5 10 50 100 mmol/L) and according to the results the step width is refined. In this example a higher resolution was chosen between 1.3 and 1.35 mmol/L. The following result is obtained (Fig. 60). [Pg.165]

The phreeqc input file is shown in Table 8.1. Note that we use sulfate for charge balance, because it is the most abundant ion. The default definition of alkalinity in phreeqc is as calcite , which is what our analysis shows, so we simply enter that number (153 mg L-1). Under the keyword REACTION, a suitable combination of moles of HCl and number of steps is found with some calculation and a certain amount of trial and error. We specify the file name of the output file to ensure we get an output file with the essential data arranged for copying to a spreadsheet. The results are shown in Figure 8.2. [Pg.159]

With its flexible and logical search language, REACCS can retrieve molecular stmctures, the atoms and bonds that are transformed ia a reaction, relative and absolute stereochemistry, the role (reactant, product, solvent, or catalyst) of a molecule ia a reaction, reaction data (eg, temperature and yield), hterature references, and keyword descriptions of reaction types. [Pg.125]

The Subject Index of over 20 000 entries has been compiled from keywords, names and formulae in the text and tables. It covers general classes of compound, specific compounds, general types of reaction, specific and named reactions, spectral and other properties, and other topics in heterocyclic chemistry. More details are again given at the beginning of the index in Volume 8. [Pg.6]

In Gaussian, a reaction path calculation is requested with the IRC keyword in the route section. Before you can run one, however, certain requirements must be met. An IRC calculation begins at a transition structure and steps along the reaction path a fixed number of times (the default is 6) in each direction, toward the two minima that it connects. However, in most cases, it will not step all the way to the minimum on either side of the path. [Pg.173]

Perform the IRC calculation (requested with the IRC keyword). This job will help you to verify that you have the correct transition state for the reaction when you examine the structures that are downhill from the saddle point. In some cases, however, you will need to increase the number of steps taken in the IRC in order to get closer to the minimum the AAoxPoinb option specifies the number of steps to take in each direction as its argument. You can also continue an IRC calculation by using the lRC=(ReStorhMaxPointe=n) keyword, setting n to some appropriate value (provided, of course, that you have saved the checkpoint file). [Pg.174]
