摘要：Precipitation of nalkanes in diesel affects cold flow property With XRD pattern, shape of crystals is able to be studied But XRD pattern has not been applied to investigation of precipitation of crystals of nalkanes appearing in diesel In this paper, XRD pattern of a series of diesel flow improver(DFI), wax and mixture of wax and DFI are analyzed The relationship between character of XRD pattern and performance of DFI is studied When sharp peak between 10°～30° is little, shape of peak is ordered and curve of peak is smooth, performance of DFI is better XRD pattern of the mixture of wax and DFI shows noncrystalline structure has changed Hence it might be considered crystallization procedure of wax be affected by DFI This work is also helpful to the full understanding of the mechanism of
