running water and 10 mL of methanol containing the GC
standard naphthalene were added. The resulting solution was
analyzed as described in the next paragraph.

Determination of the reaction products
Determination of the composition of the final reaction mixture
was made by GC and GC/MS. Qualitative analysis was ac-
complished by GC/MS using where possible authentic samples
for comparison. Quantitative evaluation of product distribution
was performed by GC with the aid of an internal standard refer-
ence (naphthalene), using response factors determined by use of
standard solutions; several specimens of such standard solutions
at different concentrations allowed quantitative analysis which
were reproducible within ±1%.
In the quantitative analysis of the catalytic reactions, the sum
of final amounts of acetophenone and phenyethanol exactly
corresponded to the amount of acetophenone initially loaded;
moreover, no other product derived from acetophenone was
detected.
