CATALYST SYSTEM CONTAINING NI(0) AND PROCESS FOR PREPARATION THEREOF |
| Abstract |
A catalyst system containing a) Ni (0), b) 4 -10 mol per mol Ni (0) according to a) a compound (1) of formula P (X<SUP>I</SUP>R<SUP>1</SUP> (XR<SUP>2</SUP> RR<SUP>2</SUP> ) (XR<SUP>3</SUP> RR<SUP>3</SUP> ) (I) wherein Xl, XR<SUP>2</SUP> , XR<SUP>3</SUP> independently represent oxygen or a single bond RR<SUP>1</SUP> , RR<SUP>2</SUP> , RR<SUP>3</SUP> represent independently, the same or differ-lint ozganic radicals; and c) 1 -4 mol per mol Ni (0) according to a) a compound (1 i) of formula (II) wherein XR<SUP>11</SUP> , XR<SUP>12</SUP>2, XR<SUP>13</SUP> , XR<SUP>21</SUP> , XR<SUP>22</SUP> , XR<SUP>23</SUP> independently represent oxygen or a single bond, RR<SUP>11</SUP> ' RR<SUP>12</SUP> independently represent the same or different individual or bridged organic radicals, RR<SUP>21</SUP> , RR<SUP>22</SUP> independently represent the same or different, individual or bridged organic radicals, Y represents a bridge group. The invention also relates to a method for the production of mixtures of monoolefin C<SUB>5</SUB>-mononitrils with an-conjugated C=C and C=N bond by .hydrocyanation of a hydrocarbon mixture containing -1 ,3butadiene in the presence of at Il7ast one such system and to a method for the production of a dinitrile by hydrocyanation of a mixture of monoolefin Cs mononitriles with a non-conjugated C=C- and C=N bond in the presence of at least one such System |
