phase optics


Something what was requested at least 100 times from the followers: separation of non miscible organic and aqueous phases. 

Since we have no money to buy optically pure BINOL ( [1,1’-binaphthalene]-2,2’-diol) I have to synthesize it from ß-naphthol in a 3 step synthesis. On the gif there is the last step of the synthesis, just after the resolution. Here I decomposed the diastereomeric salt with a lye solution and in the upper ethyl-acetate phase there is the optically pure (R)-(+)-1,1′-Bi(2-naphthol). I just need to separate the phases and evaporate to get the pure product.
