以β-环糊精包合间苯二酚双(二苯基)磷酸酯阻燃剂的制备与表征

Preparation and characterization of resorcinol bis( diphenyl phosphate) flame retardant included by β-cyclodextrin

以β-环糊精和间苯二酚双（二苯基）磷酸酯（RDP）为原料,在65℃DMAC溶液中形成β-环糊精/RDP包合物。利用核磁共振（^1H NMR）、X射线衍射（XRD）、差示扫描量热（DSC）、扫描电子显微镜等方法对包合物进行鉴定。结果表明,β-环糊精与RDP已形成包合物,当β-环糊精与RDP投料摩尔比为1∶2时,包合率最高为55.17%。

β-Cyclodextrin / resorcinol bis（ diphenyl phosphate）（ RDP） inclusion complex was prepared in DMAC solution at 65 ℃. The formation of inclusion complex was proved by1 H NMR,XRD,DSC and SEM. The result showed that the inclusion ratio of RDP reached highest value of 55. 17%,when the mole ratios of β-cyclodextrin to RDP was 1∶ 2.
