| 摘 要： | 实验研究了以叔丁醇和对二苯酚为原料合成TBHO的主要工艺参数．结果表明，常压下以叔丁醇的过量系数为160％时，以85％的浓磷酸为催化剂，在130℃的温度下反应2．5h，采用重结晶法精致工艺，可以制备出纯度为80％的TBHO，而且产品收率可达30％以上。

| Abstract: | Main technical paramengs for synthesis of TBHQ(2 - tert - butylphend) from tert - butyl alcohol and hydroquinone were investigated in this paper. The results showed that TBHQ with purity of 80 % and yield more than 30% was synthesized from tert- butyl alcohol and hydroquinone under atmospheric pressure, when excess ratio of tert - butyl alcohol was 160% and the reaction was catalyzed by 85% H3PO4 for 2. 5 hours under the temperatuer of 130. Recrystallization was adapted to get the fine product. |
