摘　　要：以酚醚和草酰氯为原料,经Friedel-Crafts酰基化反应来制得一系列苯偶酰类化合物,并通过^1HNMR、^13CNMR对目标产物进行结构表征。同时还考查了8种苯偶酰类化合物的紫外吸收性能和光稳定性能。结果表明,化合物Ⅲ1～Ⅲ8对UVB具有良好的吸收性能,而且化合物Ⅲ1和化合物Ⅲ6兼具对长波紫外线UVA和中波紫外线UVB的吸收性能。化合物Ⅲ1～Ⅲ8的光稳定性顺序为化合物Ⅲ1〉化合物Ⅲ8〉化合物Ⅲ5〉化合物Ⅲ7〉化合物Ⅲ4〉化合物Ⅲ2〉化合物Ⅲ3〉化合物Ⅲ6。A series of benzoyl compounds were obtained by Friedel-Crafts acylation using phenol ether and oxalylchloride as starting materials.The structures of the target products were confirmed by means of ^1HNMR,^13CNMR and their ultraviolet absorption characteristics and light stabilities were also investigated.The results showed that compounds Ⅲ1～ Ⅲ8 exhibit good absorbency as the UVB-type absorbents,and compounds Ⅲ1 and Ⅲ6 both functions as long-wave ultraviolet（UVA） and medium-wave ultraviolet（UVB） absorbents.The stability order of compounds Ⅲ1～ Ⅲ8 is Ⅲ1Ⅲ8Ⅲ5Ⅲ7Ⅲ4Ⅲ2Ⅲ3Ⅲ6.
