Synthetic route
In industry, it is mainly synthesized through the following two-step method
Condensation reaction: Citral (derived from Shan Cangzi oil, containing about 70% citral) is condensed with acetone in the presence of sodium hydroxide to produce pseudo violet ketone.
Cyclization reaction: Pseudo violet ketone is heated and cyclized in dilute sulfuric acid/glycerol solution to obtain a mixture of α - violet ketone (10-20%) and β - violet ketone (80-90%), which is then separated by distillation to obtain the target product.
