    摘要： A method for preparing a molecular sieving metallosilicate is disclosed which comprises

    (A) providing a mixture comprising: water, an oxide of silicon source; a mineralizing agent and/or synthesis directing agent; and a heteropolymetallate of the formula

    wherein

    A is an ion selected from the group consisting of hydrogen; one or more of the Group I-A to VI-A or Group I-B to VI-B metals; one or more of the rare earth metals; ammonium, alkyl ammonium, alkyl phosphonium or aikyl arsonium; or a mixture of two or more thereof;
    M isZn, Ga, Ge, Ti, Cr, Mn, Fe, Co, B, Ni, Rh, Zr or a mixture of two or more thereof;

    L is P, As, Si, Al, H or a mixture of two or more thereof;
    J is Mo, W, V, Nb or a mixture of two or more thereof;
    a is a number which when multiplied by the charge of A will result in balancing the charge on the complex within the brackets;
    I is a number ranging from zero to about 20;
    m is a number ranging from zero to about 20;
    z is a number ranging from about 1 to about 50;
    y is a number ranging from about 7 to about 150: d is a number ranging from about zero to about 150; and

    (B) maintaining said mixture at a temperature of about 80°C to about 300°C for an effective period of to form said molecular sieving metallosilicate.
