| titleOfInvention | One prepares N, the method for N-dimethyl tetrahydro chaff amine |
| abstract | The invention provides one and prepare N, the method for N-dimethyl tetrahydro chaff amine, makes catalyzer with Raney's nickel, the aqueous solution of raw material furfural and dimethylamine, at 40 ~ 80 DEG C, passes into hydrogen reaction under 1.5 ~ 10MPa pressure, obtain N, N-dimethyl tetrahydro chaff amine reaction mixture.The method has that raw material is easy to get, technique is simple, product yield higher than 65%, the feature such as production cost is low, the product purity more than 99.0% of the N of production, N-dimethyl tetrahydro chaff amine, can be directly used in synthesizing polybutadiene rubber. |
