酸催化合成对叔辛基苯酚甲醛的研究

Study on the Synthesis of Para-tert-octylphenol Fomaldehyde Resin By Oxalic Acid

以草酸为催化剂 ,研究了对叔辛基苯酚与固体甲醛合成对叔辛基苯酚甲醛的反应 ,结果表明 :用 1 0g草酸作催化剂 ,当对叔辛基苯酚与固体甲醛摩尔比为 1∶1 .2 ,在 1 0 0～ 1 1 0℃温度下 ,反应 3h,树脂产率可达 86.4 % ,该方法具有催化活性高 ,三废排放少等优点。

The synthesis of para-tert-octylphenol fomaldehyde resin using oxalic acid as catalyst was studied in this paper . The effect of the amount of catalyst ,the ratio of para-tert-octylphenol to solid fomaldehyde,and the reacting time was investigated,and the optimum reaction condition was obtained.
