PURPOSE:To produce ferrierite effectively with few loads of an organic compound at a comparatively low temp. by adding the specified organic compound and allowing to react each other in manufacture of the ferrierite due to a hydrothermal synthesis method. CONSTITUTION:Tetramethylammonium salt (for example, tetramethylammonium hydroxide) is used as an organic additive. Namely, an alkaline metallic salt (A) (for example, sodium hydroxide), an alumina source (B) (for example, aluminum chloride), a silica source (C) (for example, silica sol) and said organic additive are contained so that the relation shown by the formula (expressed in terms of oxide) (M is alkaline metal; R is an organic additive; a=1.6-5; b>15; c=0.05- 1) is satisfied and an aq. mixture (amount of water is about 100-1,000mol times per 1mol Al2O3) is produced and the aq. mixture is allowed to react with each other by maintaining it at 100-200 deg.C for about one day or more under self- pressure. |
