英文摘要 | Abstract This study reports the synthesis of diether compound from the reaction of α,α′-dibromo-o-xylene and 1-butanol under phase-transfer catalysis condition. The reaction rate is significantly affected by the active intermediate (QOR), which is produced from the reaction of quaternary ammonium salts (QX) and 1-butanol. This study investigates the effects of the amount of potassium hydroxide, temperature, and the amount of organic solvent on the biphasic distribution of QOR and reaction rate. |
