seen that the errors in the parameters are much smaller than the
actual values of the parameters indicating the model provides a
concentration, catalyst loading and temperature. There was no sys-
tematic pattern in the residual plot indicating that there were no
systematic experimental errors. For sake of brevity, only one plot
is shown in Fig. 18. Previously for the calculations of activation
energy, i.e. Arrhenius plot we are not using significant number of
digit. We take more significant number of digit and plotted a new
Arrhenius plot; from this plot we calculate the activation energy
32.29 kcal/mol. Thus, the model is valid.

2-Methoxynaphthalene was prepared by catalytic methylation
of 2-naphthol using dimethyl carbonate as a greener alterna-
tive. A novel catalyst calcined-hydrotalcite (CHT) supported on
hexagonal mesoporous silica (HMS) was developed. Effects of var-
ious parameters on conversion and selectivity were systematically
studied in a batch autoclave. 20% (w/w) CHT/HMS was the best
catalyst which was fully characterized. Conversion of 2-naphthol
was 92% with 90% selectivity toward 2-methoxynaphthalene.
The catalyst was easily recovered and reused without any sig-
nificant loss in activity. A kinetic model was developed for
this reaction. The reaction follows zero order kinetics based on
Langmuir–Hinshelwood–Hougen–Watson mechanism with strong
adsorption of reactants. The activation energy for the reaction is
32.29 kcal/mol indicates that the reaction is intrinsically kinetically
controlled.
