Zusammenfassung:PROBLEM TO BE SOLVED: To provide a material which is useful as a base material of a catalyst, an adsorbent, a separation agent, etc., which requires excellent high temperature heat resistance, high structural stability, high solid acidity, etc., using a mordenite type zeolite synthesized by a seed crystal addition method and having a high SiO2/Al2O3ratio as it is synthesized without dealuminum treatment. SOLUTION: This synthetic method of a mordenite type zeolite with SiO2/Al2O3=40-100 comprises addition of 0.1-10 wt% (to the weight of silica component) of a mordenite type zeolite as a seed crystal to a reaction mixture with compositions represented in molar ratio of oxides of 40
