Abstract

Synthetic saponite derivs. useful for hydrocarbon conversion such as olefin oligomerization have the general formula Ax/nn+[(Mg3-yMy)(Si4-xAlx)O10(OH2-z)Fz], A = alkyl-substituted NH4 ion and/or metals having basic or amphoteric properties, M = bivalent metal ion having ionic radius 0.050-0.085 nm, n = valence of A, x = 0.05-1.5, y = 0.05-2.95, and z = 0-1.8. Adding amorphous silica-alumina 40, Mg(OAc)2.4H2O 36.5, and Ni(OAc)2.4H2O 84.7 g to 75.4 g H2O, stirring with 13.9 g 25% aq. NH3, heating at 240 Deg for 60 h, and treating with NH4Cl soln. gave 46.0 g Ni saponite (I). I was calcined at 550 Deg and used in the oligomerization of C2H4 giving oligomers (up to C10) with 54% conversion and 99.5% selectivity
