摘要
以二苯胺和含C12 的混合异构烯烃为原料 ,通过烷基化工艺 ,研制出了适于高温条件下应用的不含磷、锌元素的液态胺型无灰抗氧剂双十二烷基二苯胺 (HAO)。对HAO的组成、结构进行了分析 ,在实验室里考察了HAO的油溶性及热失重温度 ,并应用几种不同的氧化评定方法对其抗氧化性能进行了评定。试验结果表明 ,HAO抗氧剂具有油溶性好、热安定性好、高温抗氧化能力较强的特点。用 0 .5
A liquid amine ashless antioxidant HAO without phosphorus and zinc was prepared by alkylation of diphenylamine and 12 carbon iso olefin mixture, which can be applied at high temperature. The composition and structure of HAO was analyzed and its oil solubility and thermo gravimetric analyses were taken. Its anti oxidation performance was evaluated with various oxidation evaluation methods. The laboratory result showed that HAO possessed the features of good oil solubility, good thermal stability and high anti oxidation ability at high temperature.
