2,5-二叔丁基对苯二酚

2,5-二叔丁基对苯二酚用途

【用途一】
用作天然橡胶、合成橡胶及乳胶的抗氧剂
【用途二】
用作天然橡胶、合成橡胶及胶乳的抗氧剂。能延缓硫化胶及未硫化胶的氧化老化及紫外光老化，是一种不污染橡胶制品的、日光照射也不变色的无着色性、非污染性防老剂。耐氧化方面优于通常的防老剂，亦可提高橡胶制品的耐热性和耐屈挠龟裂性。有效配合量为0.5-1份。该品对胶粘剂的防老化效果亦好。容易分散，对硫化没有影响。该品宜用于制造浅色橡胶制品、医疗用品、胶乳制品和胶粘带等。亦可作为油类和合成树脂的抗氧剂。在塑料工业中可作为聚烯烃和聚甲醛的热、光稳定剂。
【用途三】
抗氧剂

2,5-二叔丁基对苯二酚制备

1.异丁烯的制备异丁醇经气化后，连续定量地通过触媒活性氧化铝，在(380±10)℃下进行脱水反应。生成的异丁烯气体。经冷却、分水、干燥，供烷基化使用。

防老剂Alba的制备在反应釜内加入对苯二酚和催化剂硫酸，搅拌下加热至65℃时通入异丁烯，进行烷基化反应。反应生成防老剂Alba,经60℃热水洗涤，再用碳酸钠中和，最后再用70～80℃的水洗至中性、冷却至10～15℃结晶，离心脱水后溶于热乙醇中进行重结晶，即得成品。

2.由对苯二酚与异丁烯反应制得。反应式如下：
