| titleOfInvention | Hydrogenation method for activation of hydroxy-terminated butyronitrile catalyst |
| abstract | A hydrogenation method for activation of a hydroxy-terminated butyronitrile catalyst belongs to the field of hydrogenation catalysis. Raw hydrogenation materials adopted by the method comprise liquid hydroxy-terminated butyronitrile without any termination protection treatment and liquid hydroxy-terminated butyronitrile using hexamethyldisilazane for termination protection treatment. An activation method of the catalyst mainly comprises the steps of adding organic compounds such as alcohol and ketone as promotors and conducting selective hydrogenation on unsaturated double bonds of a polymer at 80-100 DEG C and 0-5 MPa for 2-12 h. According to the hydrogenation method, few organic compounds such as the alcohol and the ketone are used as the promotors, so that the reactivity of the catalyst is improved effectively, and the hydrogenation degree is increased greatly. In addition, the catalyst consumption required for reaching the same hydrogenation degree is reduced greatly, and the cost is saved significantly. According to the hydrogenation method, the high hydrogenation degree of the liquid hydroxy-terminated butyronitrile without any pretreatment is achieved for the first time, which cannot be achieved by other catalyst systems at present. |
