PROCESS FOR PREPARING DICYANOBUTENE |
| abstract |
Dicyanobutene is prepd. by reacting butadiene with hydrogen cyanide and oxygen or an oxygen contg. gas in the presence of a catalyst comprising copper ions and halide ions and a catalyst solvent. The product, principally 1,4-dicyanobutene is an intermediate in the prepn. of adiponitrile and hexamethylenediamine. Previously processes have either been 2-stage involving a chlorination first or alternatively have used a Ni catalyst which results in the introduction of only 1 nitrile group. |
