Synthesis method
1. Use phenol and isobutylene to carry out tert-butylation reaction in the presence of aluminum trichloride, and then use Rede’s Nickel W7 to catalyze hydrogenation to obtain compounds with two geometric structures, of which the trans structure accounts for more than 70%.
2.Using phenol and isobutylene to carry out tert-butylation reaction in the presence of aluminum trichloride, and then catalytically hydrogenating it, a mixture of two geometric structures can be obtained .
Purpose
1. Because patchouli essential oil is easy to change color, adding this product can overcome the disadvantage of discoloration. Since this product was developed in the 1960s, its ortho-isomers and corresponding ester compounds have been widely used in the formulation of daily chemical fragrances, and the direct dosage can now reach 10%.
2.Patchouli essential oil is easy to change color, and p-tert-butylcyclohexanol can replace patchouli oil that has discoloration problems in essence. It has been widely used in the formulation of daily chemical fragrances, and the direct dosage can reach 10%.
