乙醚

It is involved in the synthesis of triphenylcarbinol. In this pater, based on the principle of the ultrasonic wave radiation and its advantages, triphenylcarbinol was synthesized by ultrasonic irradiation. We have researched the influence on the synthesis of triphenylcarbinol for the solvent of different purity.
