Ethanol → Canthaxanthin

참여 물질

반응 단계

Into a flask was charged 0.5 gm of β-carotene and 10 ml of chloroform. The mixture is stirred to form a solution. Into this solution was charged 1.6 ml of the oxidant solution described in example 1. The mixture was stirred for 1.5 hours to complete the reaction. The phases were separated and the organic phase was washed with water once and evaporated to yield a residue that was dissolved in 10 ml of warm ethanol. This ethanol solution was added slowly to 50 ml of water to form a precipitate which was filtered and dried to yield 85% yield of canthaxanthin of approximately 80% purity.
