Method of producing 4-biphenyl p-tolyl ether |
| abstract |
The use of 1,3-dimethyl-2-imidazolidinone or sulfolane as a reaction promoter is effective in the production of 4-biphenylyl p-tolyl ether, which is useful as a sensitizer for heat-sensitive recording paper, by reacting p-phenylphenol with a p-halotoluene in the presence of a copper catalyst. |
