Beschreibung
Zusammenfassung:	The invention relates to a catalytic distillation technique for synthesizing methyl tertiary butyl ether. The catalytic distillation technique for synthesizing methyl tertiary butyl ether is characterized in that a catalytic distillation tower includes an upper tower and a lower tower serially connected with each other, the upper tower is composed of a rectifying section and a reacting section, the lower tower is a stripping section, pressure of the upper tower is the pressure in conventional catalytic distillation synthesis of methyl tertiary butyl ether, the pressure of the lower tower is lower than that of the upper tower, latent heat of top steam of the upper tower is used to heat a reboiler at the bottom of the lower tower, and the upper tower is provided with an auxiliary condenser. The catalytic distillation technique has the advantages that the catalytic distillation technique is low in energy consumption, energy is saved by more than 45% of that of a conventional catalytic distillation tower, product
