Beschreibung
Zusammenfassung:	The invention relates to a disperse dye compound as well as a preparation method and application thereof. The general formula of the disperse dye compound is shown in the formula (I), wherein in the formula (I), X1 is hydrogen, hydroxyl or acetamido; X2 is hydrogen, methoxyl or oxethyl; R1 is benzyl, C1-C4 alkyl or -CH2COOCH3; R2 is C1-C4 alkyl or-CH2COCH3, n is 1 or 2; when R1 is equal to -CH2COOCH3, n is equal to 1. The preparation method comprises the following step of coupling a diazotized compound shown in the structural formula (II) with a compound shown in the structural formula (III) to prepare the disperse dye compound in the formula (I). A disperse dye provided by the invention contains the disperse dye compound. The disperse dye is used for dyeing hydrophobic fiber materials like polyester fibers, has excellent various fastness properties, and particularly has outstanding acetate fiber stained color and nylon stained color fastness properties in washing fastness.
