| titleOfInvention | A kind of technique of continuous synthesis β-isophorone |
| abstract | The technique that the invention discloses a kind of continuous synthesis β isophorone, including: with α isophorone as initiation material, with molecular sieve as catalyst, reaction rectification technique is used to carry out isomerization reaction in tower reactor reactor, overhead collection at tower reactor reactor obtains β isophorone, release heavy component in tower reactor, reclaim and obtain α isophorone and follow and carry out ring set use；Described isomerization reaction condition is as follows: reaction temperature is 180 290 DEG C, and reaction pressure is 0.05～0.30MPa, and the quality of described molecular sieve is the 0.3 5.0% of described α isophorone.In this technique, molecular sieve joins together with α isophorone in tower reactor and carries out being fully contacted, reacting, and the β isophorone obtained constantly is distilled off, and the selectivity of product is high, the consumption of molecular sieve catalyst is few, and catalyst and heavy constituent material all can be easy to reclaim and separate. |
