| titleOfInvention | Modified hierarchical porous molecular sieve catalyst and preparation method thereof, and production method of 3-methyl-2-buten-1-ol |
| abstract | The invention belongs to the technical field of producing 3-methyl-2-butene-1-alcohol, and in particular relates to a modified hierarchical porous molecular sieve catalyst and a preparation method thereof, 3-methyl-2-butene-1-alcohol The production method comprises: a) purifying the isomerized raw materials to be reacted through a purification process, and controlling the content of impurities contained in the isomerized raw materials; the impurities include formaldehyde, nitrogen-containing substances, metal ions and formic acid One or more of the root, in the purified isomerization raw material: the formaldehyde content is below 100ppm, the nitrogen-containing substance content is below 20ppm, the metal ion content is below 10ppm, and the formate content is below 100ppm; b) in the catalyst Under the action of I, the purified isomerization raw material is subjected to isomerization reaction to obtain 3-methyl-2-butene-1-alcohol. The production method of the invention can greatly improve and prolong the activity and life of the catalyst. |
