| titleOfInvention | Catalyst for synthesizing N,N-diethylpropynylamine and preparation method thereof |
| abstract | The invention discloses a catalyst for synthesizing N,N-diethylpropynylamine. The catalyst uses coarse-porous microsphere silica gel as a carrier and supports a mixture of copper salt, bismuth salt and cerium salt. The catalyst provided by the invention uses coarse-pore microsphere silica gel as a carrier, which increases the specific surface area of the catalyst. The specific surface area of the catalyst is dozens or even hundreds of times that of conventional catalysts, and can fully contact with the reaction raw materials, increase the reaction rate, and shorten the reaction time. time, reducing the probability of side reactions, while greatly reducing the amount of catalyst used; and the catalyst is a mixture of copper salt, bismuth salt and cerium salt as an active ingredient, copper salt, bismuth salt and cerium salt The synergistic effect can effectively inhibit the side reaction in the process of synthesizing N,N-diethylpropargylamine, improve the selectivity of the reaction, and improve the yield and purity of N,N-diethylpropynylamine. The invention also provides a preparation method of the catalyst. |
