    摘要： A molecular sieving metallosilicate is disclosed which comprises a complex represented in terms of mole ratios of oxides by the formula: ##STR1## wherein A is an ammonium, alkyl ammonium, alkyl phosphonium or alkyl arsonium ion; D is an alkali or alkaline earth metal ion or a mixture of two or more thereof; E is selected from the group consisting of Al, B, Mo, W, Fe, or a mixture of two or more thereof; M is a tetravalent metal selected from the Lanthanide or Actinide series; a is a number ranging from zero to about 25; b is a number ranging from zero to about 1.5; c is a number ranging from zero to about 0.3; d is a number ranging from about 20 to about 500; e is a number ranging from zero to about 200. The X-ray diffraction pattern for these metallosilicates indicates a ZSM-5 like crystalline structure. A method for making these metallosilicates, and a method for dehydrating and reforming methanol using these metallosilicates are disclosed.

    摘要： A method for preparing synthetic oils characterized by a high viscosity index and prepared from 1-olefin is described. The method comprises polymerizing a 1-olefin or a mixture of 1-olefins in the presence of(a) at least one transition metal halide catalyst,(b) at least one alkyl aluminum compound containing up to about 15 carbon atoms in each alkyl group and up to about 40 carbon atoms per molecule as a co-catalyst, and(c) a saturated alkyl fluoride.The homopolymers and copolymers prepared in accordance with the method of the invention generally are characterized by a high viscosity index such as between about 100 to 300. The homopolymers and copolymers are useful as synthetic lubricants and as additives to synthetic or mineral oil lubricants for modifying the viscosity index characteristics of the lubricants.
