Swelling and pillaring of the layered precursor IPC-1P: tiny details determine everything
Original language description
The influence of swelling (i.e. the size of tetraalkylammonium surfactant molecule, the presence of tetrapropylammonium hydroxide (TPAOH), pH) and pillaring (i. e. the ratio between the swollen precursor IPC-1P and tetraethyl orthosilicate) conditions onthe structure and textural properties of the resulting materials was studied in detail for IPC-1P, which is the layered precursor of zeolite PCR. The swelling of IPC-1P proceeds efficiently under basic conditions both in mixed CnH2n+N-1(CH3)(3)Cl/TPAOHsystems and in CnH2n+N-1(CH3)(3)OH (n = 8, 10, 12, 14, 16, 18) solutions at pH = 13-14. The intercalation of CnH2n+1N+(CH3) 3 in IPC-1P resulted in the formation of expanded materials with interlayer distances growing with increasing length of the alkylchain in CnH2n+N-1(CH3)(3) +: 1.59-1.86 (n = 8) < 1.89-2.11 (10) < 2.05-2.26 (12) = 2.08-2.26 (14) < 2.37-2.43 (16) < 2.57-2.71 (18) angstrom. IPC-2 zeolite was formed during calcination of IPC-1P samples swollen in CnH2n+1N(CH3) 3OH solu
