PURPOSE:To obtain a crystalline porous body compsn. comprising crystals of aluminophosphosilicate having >=10mu length of one edge by selecting the compsn. of aq. mixture to be fed to the hydrothermal reaction and conditions of the hydrothermal reaction. CONSTITUTION:Aluminium hydroxide, and further morpholine and water are added to aq. phosphoric acid, and the mixture is stirred. After adding silica sol thereto, morpholine and water are added again and the mixture is further stirred. The mixture is charged in a ''Teflon'' vessel and the vessel is housed in a stainless steel vessel, and hydrothermal reaction is performed at ca. 200 deg.C for ca. 48hr. By this method, a crystalline porous body compsn. comprising aluminophosphosilicate crystal giving a spectrum of principal X-rays diffraction as shown in the Table-1 and having >=10mu length of one edge.
