| titleOfInvention | A kind of composite modified molecular sieve catalyst, its preparation method and its application |
| abstract | The invention provides a modified molecular sieve catalyst of 3-methyl-3-butene-1-alcohol and a preparation method thereof. The 3-methyl-3-butene-1-alcohol catalyst, with molecular sieve as the parent body, is treated with steam, acid washing, and compound modified by alkaline phosphate, and can be used for the synthesis of 3-methyl from isobutene and paraformaldehyde -3-butene-1-alcohol in the reaction. Compared with the traditional process, the catalyst provided by the present invention has the advantages of suitable acidity and alkalinity, suitable pore size, and simple preparation method. At the same time, the catalyst carries out the condensation reaction of isobutene and formaldehyde in the pressure reactor, which effectively reduces the reaction temperature and reaction pressure, and the catalyst is easy to separate after the reaction, which reduces the operation and energy consumption in terms of separation, and is an isobutene condensation method to produce 3- Methyl-3-butene-1-alcohol offers great application prospects. |
