Procedure
The catalyst stratum was heated and when the temperature of the catalyst stratum reached 280° C., a starting compound mixture gas consisting of catechol and methyl alcohol in a molar mixing ratio of 1:3.44 and evaporated in an evaporator was fed, at a feeding rate of 10.5 g/min, together with nitrogen gas, into the reaction tube for 14 hours, to cause a catalytic dehydration (etherification) reaction of catechol with methyl alcohol and provide monoalkyl ester of catechol, i.e., guaiacol.
