The invention relates to a nano-copper-graphene composite catalyst for directly hydroxylating benzene to prepare phenol and a preparation method of the nano-copper-graphene composite catalyst. The composite catalyst is composited by nano-copper and grapheme with a mass ratio of (0.05-30):1. The ...
How would you prepare diphenylmethane, (Ph)_2CH_2, from benzene and an acid chloride? How would you synthesize 2-ethylhex-2-en-1-ol from butanal? Why do we use a mixture instead of only ether or only hexanes in a Wittig reaction? Explain how you would prepare a 1.135 m solution of...
