  14. Initial ideas of reaction process Photooxidation of cyclohexanol in literature alcohols: 1-pentanol, 2-pentanol, 3-pentanol, cyclohexanol Product Reaction:under atmospheric oxygen.The catalyst (100 mg), alcohol (10 mL), at room temperature, using a cold mirror with a 500 W ultrahigh-pressure Hg lamp. www.themegallery.com

  15. Initial ideas of experiment project • Reactor condition temperature:25℃～27℃ pressure:1atm catalyst/solution=0.1%～0.2%w/v solvent/reductant=5～9 catalyst selection:determine electrode potential of cyclohexanone/cyclohexanol catalyst preparation:hydrothermal www.themegallery.com
