| Abstract: | A new antioxidant, i.e. 2,2＇ - ethylidenebis （4,6 - di - tertiary - butylphenol）, is synthe- sized with 2,4 - di - tert - butylphenol and paraldehyde as the materials, and the effect of reaction conditions on the synthesis reaction was studied. According to the results, the optimum process conditions are： n （2,4 - di - tert - butylphenol） ： n（paraldehyde） ： n（ dodecylbenzene sulfonie acid） = 1 ： 0.25 ： 0. 0336, the re- action temperature is 90 ~C, and the reaction time is 16 h. The product yield is 88.7% with the product puri- ty being 99.8% at the optimum conditions. It is confirmed by the techniques of melting point measurement, infrared analysis and nuclear magnetic resonance analysis that the target product is 2,2＇ -ethylidenebis （4,6 - di - tertiary - butylphenol）. |
