Reaction Steps
When the temperature of the catalyst stratum reached 280° C., a starting compound mixture consisting of catechol and methyl alcohol in a molar mixing ratio of 1:3.44 was evaporated in a evaporator, and the resultant starting compound mixture gas was fed in a feeding rate of 10.5 g/min. together with a nitrogen gas into the reaction tube for 14 hours, to etherify catechol with methyl alcohol and to produce a dihydric phenol compound monoalkylether, i.e., guaiacol. The reaction mixture gas discharged from the reaction tube was cooled to a temperature of 40° C. The resultant liquefied product was collected from the reaction mixture.
