I made the Grignard reaction with phenylmagnesiumbromide react with ethyl acetate to give 1,1-diphenylethanol. After drying with sodium sulfate, all in the solution was ether and crude oil solid. After all the ether evaporated or remove by simple distillation, I have is the product. Do I need to all do the simple distillation again to get the product 1,1-diphenylethanol which has the boiling point 165°C and the melting point 77 - 81°C. The product is white crystals from the literature, but it does not mean literature has everything to explain. All I want to know then how can I get the white crystals from the crude brown oil solid? For the recrystallization, I tried acetone as solvent and boil the solution with it. Also, after cooling I add the norit, decolorizing charcoal to decolorize the solution. After that I let the solution cooled, but I do not get the crystals. Please, I need help a lot in getting the product 1,1-diphenylethanol. I need step by step help what I did wrong and what can be done right to get the product.© BrainMass Inc. brainmass.com October 9, 2019, 11:15 pm ad1c9bdddf
