The retention times of the components are summarized in Table 2. Anisole - the product of phenol O-alkylation was not included as a reference spectrum for the method of FTIR analysis, because preliminary tests with the GC-MS analyzer showed that it does not occur in the reaction products on the TZC-3/1 catalyst.
