摘要
研究了利用DSC快速测定柴油冷滤点的方法。在N2氛围下以 10℃ min的降温速度进行测试。结果表明 ,DSC法测定的冷滤点与常规法测定的冷滤点接近 ,说明此方法可行 ,两种测定方法拟合的较好。对测定方进行重复实验 ,标准偏差 <4。本方法操作简单、快速 ,试样量少 。
The cold filter plugging point (CFPP) of disel fuel was determined by DSC analysis at the colding rate of 10 ℃/min in nitrogen. the CFPP of disel fuel by DSC shows some correlation with the CFPP by standard method. The relative standard deviation of analytical results is less than 4 %.The method is simple,rapid and accurate for determination of disel fuel contained wax.
