The synthesis of myrtenal was carried out in the home-made photochemical reactor with α-pinene as raw material and halogen lamp as light source.The new preparation technology of high additional value myrtenal with photosensitive catalytic oxidation of α-pinene was studied.The influence laws of photosensitive oxidation reaction conditions on the conversion rate and selectivity of the reactions were investigated.Gas chromatography analysis showed that conversion rate of the materials and selectivity of the pr...
