| titleOfInvention | Method for preparing 3,5,5-trimethyl-3-cyclohexenone with high purity |
| abstract | The present invention is selected from 0.1 to 30 parts by weight of metal sulfate and metal halide relative to 100 parts by weight of α-isophorone in a temperature range of 180 ° C to 300 ° C and a pressure range of 0 to 5 kg / cm 2 from α-isophorone. A step of obtaining β-isophorone through isomerization using a heterogeneous catalyst alone or in combination, separating the β-isophorone through a distillation reaction, and recovering unreacted α-isophorone to the reactor. It relates to a method for producing high purity β-isophorone. The catalyst system according to the present invention is not only economical as a general-purpose chemical, but also a heterogeneous catalyst system, which can be designed as a continuous process of continuously injecting reactants while maintaining the catalyst in the reactor because deterioration does not occur for a certain period of time.
